Abstract:
|
University departments in the STEM fields often work to develop partnerships and collaboration with K-12 school districts and other community partners. What are the issues with building a bridge from current research and practice in physics and other science and engineering to inquiry-based activities for the K-12 classroom? What are challenges to be addressed when working with teachers or students? How can one go from one-shot, feel-good demonstrations to sustained support and student achievement? What are the possible sources of funding for developing programs? How can university faculty and students be engaged in outreach work? Examples from The Science House at NC State University and other programs will be presented. See http://www.science-house.org/ for information and resources.

Abstract:
|
Over the past year, Cornell's Laboratory for Accelerator Based Sciences and Education has been field-developing its science outreach mobile programming. An iterative process based on existing models, our expansion includes a theatrical kid-powered physics demonstration show, the use of informal venues for science experiences, and bringing science into family conversations with make-and-take exploration. Each component is driven by core motivations: illuminating the simple intrinsic beauty of physical phenomena, making physics familiar and accessible, and bringing people together in the context of science. Practical considerations include: the use of cheap and available resources, establishing a brand, building and maintaining a enthusiastic team of volunteers, and building a following. There are also challenges: how to teach without being didactic, how to provide problem-solving experiences that aren't frustrating, and how to measure success.

Abstract:
|
The LIGO Lab in Livingston, LA, searches for gravitational waves or ripples in space-time caused by massive objects undergoing incredible accelerations -- such as colliding neutron stars. LIGO Science Education Center seeks to connect this active scientific research to the public through simple science activities and demonstrations. At LIGO-SEC students of all ages learn about gravity waves by developing their understanding of mechanical waves, sound waves, light waves, and general wave properties. Kathy Holt, LIGO Science Educator, will provide an overview of several low-cost demonstrations and activities that LIGO-SEC uses to explain wave properties and how an interferometer works. Demonstrations will bridge the gap from interference in a hanging wave machine to lissajous patterns from a membranophone. Material will be provided for participants to build at least one demonstration.

Opportunities are expanding for physicists and physics technicians to be involved in outreach efforts in the media. There is a growing interest amongst the general public to truly understand physics concepts and to see it presented in an interesting way. Improving the public's understanding of physics can lead to a greater appreciation for science. This will be illustrated with snippets from recent projects and other colleagues' involvement at USC.

Abstract:
|
Many physics departments have made significant changes to their graduate programs in the last few years. These changes were partly driven by the increasing specialization of the field and the increasing number of interdisciplinary programs. Changes included modifications of the core curriculum and the comprehensive exams. Are these changes effective? Are the students better prepared for non-academic/industry careers? Are these changes improving the traditionally high drop-out rates? It is still too early to answer these questions, but the departments are encouraged to document and analyze the results of the implemented changes carefully so that the "best practices" can be implemented in other departments.

Abstract:
|
It is particularly challenging in the context of physics PhD programs to construct objectives and schemes to systematically assess whether these objectives are met. This is for two reasons. The first is that these programs focus on research. It is probably true that there is broad agreement the purpose of these programs is to train students to become independent and highly competent researchers. The challenge is to articulate in a precise and measurable way precisely what skills and/or knowledge an independent and competent researcher needs to acquire. The second challenge is related to the great diversity of research subfields that exist in Physics PhD programs. Students who work on experimental "big science'' such as an LHC experiment need to learn a radically different set of skills than students working in say biophysics or computational plasma physics. Given the disparate needs of these subfields, it is particularly difficult to construct meaningful objectives that apply to all of these.

Three decades of my industrial partnerships with more than 10 companies have led to significant publications, patents, start-ups, and jobs. My 20 graduated PhD students have upwards of 150 patents and 200 publications and abstracts, and have worked in remarkably diverse areas, from radiation, imaging, and heat transfer physics, to magnetic particle ferrofluids, and sensor development for contaminated industrial fluids. I am connected to three new manufacturing companies with more than 100 employees, 20% of whom have been trained in my computational laboratory. This is aligned with a national award-winning master's program in physics entrepreneurship, where I've been co-advisor for 25 graduates. As an outgrowth of a unique imaging course, my former students and I have co-authored a 900-page textbook referred to as the "daily companion of the MRI scientist." I discuss the relevance of all of this to general physics graduate education, especially in today's funding climate.

Abstract:
|
Physicists acquire data from a multitude of sources, ranging from their own experimental equipment or numerical simulations to the outputs of large experimental collaborations. However, the mere acquisition of this data is not enough: it is essential to know how to analyse and interpret it once it has been gathered. We expect that physics degrees will equip our students with the necessary analysis skills, but do they? We have formulated a diagnostic test of data-handling skills, and have deployed it in a number of universities across the UK and Ireland. Our findings suggest that student abilities in data handling are not being strongly developed by typical laboratory instruction, and that explicit tuition of the required techniques is needed. Furthermore, we find that part of the problem may be that the graduate teaching assistants we rely on may themselves not possess fully developed skills in this area.

Abstract:

We describe a pilot study undertaken in a first-year physics class at the University of Edinburgh, in which students were tasked with creating their own assessment content in the form of multiple- choice questions. Using the PeerWise online system, a regular homework assignment was substituted for one in which students were required to author at least one original question, answer five others contributed by their peers, and rate and comment on a further three. The question repository was not moderated during the assignment, with tutors merely observing. The talk will discuss the scaffolding we provided for students in order to help them create questions and illustrate examples of engagement with the task and the exceptionally high quality of questions and comments provided by the student community. We also present correlations of degree of engagement with the task with end-of-course assessment performance.

Abstract:
|
In the last decade, physics researchers around the world have studied student perceptions and beliefs on physics and learning physics. Several instruments have been used to measure these perceptions and to identify how close they are to perceptions of experts. Recently, we have administered a newly developed Arabic version of the Colorado Learning Attitudes about Science Survey (CLASS) to a sample of senior physics-major students at King Saud University (KSU) in Riyadh, Saudi Arabia. The survey was distributed to about 100 male and female students over a three-year period (2009-2011). We will present our findings of perceptions and beliefs of undergraduate physics majors about physics and learning physics at KSU. We will take a closer look at how their perceptions compare to those of experts. An analysis of how these perceptions compare to the perceptions of a sample of freshmen students will also be presented.

Abstract:
|
Most post-secondary physics courses in Brazil offer no meaningful formative assessment opportunities. We implemented online homework with immediate feedback in two courses, one with traditional learners at a public university, and one with nontraditional learners at a private university. In addition, at the public university, clickers were used in lecture. While surveys showed broad acceptance of these techniques by the students and the belief that they helped in learning, grades did not significantly improve - instead, we observed a narrowing of the grade distribution toward mid-range grades at the public university, and no difference at the private university. Our study also identifies a number of logistical and organizational hurdles that need to be overcome before a hopefully more successful implementation of these techniques should be attempted.

Abstract:
|
Mathematics is a gateway for learning science and thus limits the number of students choosing physics as a discipline of study. In Cameroon, this limitation is exacerbated by the introduction of algebra and early math and science tracking in secondary school. Textbooks prescribe classroom practices and relationships between content, teachers, and students, especially in Cameroon where they have strong foundations in European pedagogy and are often the sole resource in the classroom (Fonkeng, 2007). In this study, we examined how a mathematics textbook served to mediate the structure and interactions for two classes at a secondary school in Yaoundé, Cameroon. This research provides insight into how a textbook informs algebra instruction in an effort to better understand its role in supporting or constraining access to the fields of math and science.

Abstract:
|
We create a new Japanese version of the Force Concept Inventory (FCI) by combining three existing versions administered at three universities in Japan. The new version is for distribution to high schools and universities to assess students' preconceptions. The three existing versions are quite dissimilar because of differences in the interlingual translation stemming from large variation of expression in the translator's personal sense of language. We identify three elements of the interlingual translation that can alter the context of the questionnaire. The first element is the coining of scientific terms, such as velocity and acceleration, for school use so as to differentiate from everyday language. The second element is the use of gender expression, which is not necessary to describe in questionnaires in Japanese. The third element concerns lifestyle and cultural differences. For example, a car pushing a truck at cruising speed does not occur in Japan.

Abstract:

The Physics Education Group at the University of Washington has been investigating student learning in an upper-division laboratory course in analog electronics. Our findings indicate a need for research-based instructional materials that are expressly designed to help deepen student understanding and to address specific difficulties identified through research. As we begin this curriculum-development effort, we plan to draw on our extensive experience designing research-based and research-validated materials for use in special laboratory-based, inquiry-oriented courses for K-12 teachers.1 In this talk, I will highlight the role of experiments in instructional strategies that have been shown to strengthen the conceptual understanding of K-12 teachers. I will also reflect on how such approaches may be implemented in upper-division laboratory courses.

Abstract:
|
Physical optics combines with computational physics to make three experimental project areas especially rich in experimental breadth (optics, electronics, acoustics, fluid dynamics, along with structural and magnetic properties of materials), in addition to facilitating year-to-year student/faculty creativity. Stroboscopic holography techniques with a high (130 - 160) dB gas resonator allow real-time imaging of sound patterns at resonance as gas density variations impact the index of refraction and produce quantifiable fringe motions at pressure antinodes. A steel tuning fork is rich in torsional and transverse modes that yield to spectral analysis and computational FFT work with COMSOL. Stroboscopic holography produces quantifiable video images of these modes that may be compared to spectral and COMSOL predictions. Rapidly changing magnetic fields in a material produce Faraday-effect induced interferometric phase shifts between circularly polarized beams, and real-time fringe readouts can measure rapidly changing fields at the level of a few gauss in TGG.

Abstract:

I report on an undergraduate course on quantum mechanics with a lab component. The lab consists of five experiments with correlated photons for students to learn applications of quantum mechanics. Optical components are represented by matrix operators. Hilbert spaces can be momentum modes (propagation along x or y directions), polarization modes (horizontal or vertical), or combinations of these for one or two photons, forming two or four-dimensional spaces. The experiments explore basic quantum mechanical operations such as basis projection, basis rotation, superposition and measurement. Experiments also touch modern themes such as the concepts of qubits and entanglement. We use two optical layouts, each set up on a 2' x 5' optical breadboard.

Abstract:
|
Many students have a difficult time grasping quantum mechanical models and, particularly given that the most popular undergraduate text on quantum (Griffiths) forgoes references to real experiments, a new generation of instructional experiments is deemed to provide the absolutely critical visualization and tangible proof that are needed to convince students of key elements of quantum theory. Such instructional labs have been featured highlights of the 2009 Advanced Lab Topical Conference in Ann Arbor and of the 2010 Gordon Conference on Physics Research and Education, and have also been incorporated into the ALPhA Immersion Program, which provides hands-on training for lab instructors (e.g., in demonstrating the existence of photons, single-photon interference, indistinguishability and the quantum eraser, entanglement and tests of Bell's inequalities, etc.). This led us to establish a group focused on furthering efforts to make these sorts of labs more affordable.

Abstract:
|
The University of Colorado Boulder is in the early stages of a 2.5-year research-based redesign of our upper-division physics lab courses. There has been a nationwide resurgence of interest in advanced physics labs among instructors and faculty, but the PER community to date has focused on introductory and lecture-format classes. Little research has been conducted on these uniquely sophisticated and resource-rich learning environments in terms of goals, measurements of learning, and outcomes of modification. We are applying the existing research-base and methods of PER as a tool to make our labs better with the dual purpose of finding generalizable lessons about effective instruction in advanced lab courses. We will report preliminary outcomes that include our process of modification, learning goals, assessment frameworks, and a revised lab example.

Abstract:
|
Over the last several decades, research has challenged the efficacy of the traditional lecture-based instructional model of undergraduate physics education. As a result, a large number of reform-oriented instructional innovations have been developed, enacted, and studied in undergraduate physics courses. While previous work has shown that the impact of course innovations on student learning has been overwhelmingly positive, it has also been highly variable. The purpose of this analysis is to investigate this variability. For this analysis 170 published studies on undergraduate physics course innovations were coded with respect to the characteristics of the innovations as well as the methodological characteristics of the study designs. The findings of this analysis have indicated that nearly half of the variability can be accounted for by study design characteristics rather than by characteristics of the innovations used. However, a subsequent analysis has highlighted some of the critical characteristics of more effective innovations.

Abstract:
|
As the rest of the world catches up to the U.S. in industrial output and technological sophistication, our continued economic prosperity will depend on strengthening our historical success in generating new ideas. While there are limited efforts to foster creativity and innovation through formal and informal instruction in the business world, few efforts exist in science or engineering education. To address this, the Colorado School of Mines has recently created a dedicated Tablet PC classroom where we hold an elective physics course for the purpose of improving creativity in our students. In this talk, we report on the structure of the course and the technologies used. The latter include pedagogical implementations of InkSurvey, a free web-based software package that enables detailed, real-time interactions with the instructor. We assess student progress via the Torrance Test of Creative Thinking, and discuss early work towards developing a physics-specific instrument for measuring creativity.

Abstract:
|
Clickers are widely used for formative assessment in physics classrooms, but current clicker systems have numerous limitations. In particular, most clicker systems have limited question formats beyond multiple-choice, and provide only limited ways for instructors to use data to improve instruction. We will introduce a new web-based system we have developed that allows students to use laptops and smartphones to answer many different kinds of questions (e.g., indicating the direction of a vector, or entering an algebraic expression) and allows instructors to use the data in real time to automatically group students for peer instruction based on their responses and their reported geographical locations in the classroom. Based on an initial deployment of this system in an introductory electricity and magnetism course, we will show some examples of what can be learned about student understanding from non-multiple-choice items and what can be learned about peer instruction from automatic grouping.

Abstract:
|
Students in an algebra-based physics course were required to complete a compare and contrast activity each week. The treatment was used to examine whether direct problem comparisons are useful for facilitating student awareness of physical, deep-structure problem characteristics. Students were expected to write detailed arguments as to how two problems of their own selection from the weekly homework assignment were similar and different from one another. Handwritten feedback was offered after each assignment, and students were deducted points if their responses were considered too vague. Pre- and post-treatment similarity ratings surveys were used to evaluate the emphasis students placed on deep-structure. The survey required students to rate the similarities between eight pairs of problems of varying similarity, and write a description that supported their numerical rating. This talk will summarize student survey responses before and after treatment, and compare any trends with previous semesters where no immediate feedback was offered.

Abstract:

There is great potential in adapting, for the middle-school classroom, instructional strategies and curricular materials developed and validated for use with college students. Substantial modifications in content, format, and instructional design are needed and must conform to a variety of constraints such as time availability for instruction and grading, equipment and administrative resources, etc. I will describe my experiences in adapting PER-based materials and methods for weekly science classes taught to grades 5, 6, 7, and 8 during the 2010-2011 academic year. The context was a one-hour class taught each week to five different classes, all in the setting of a university instructional laboratory.

Abstract:
|
We have implemented peer instruction in an introductory level conceptual physics course for non-science majors, based on the success that others report with this method.(1) We expected to see that learning from peer conversation, as evidenced by answering conceptual questions correctly following discussion, would correlate with course grade, but did not observe any link. We did, however, note moderate correlation between answering a conceptual question correctly prior to peer conversation and course grade, indicating that while peer conversation improves the interactivity of a lecture course, interaction may be more important than arriving at the correct answer to student success.

Abstract:
|
Research has shown that students have several misconceptions about pulleys. To construct a mental model of how pulley systems work, students must elicit and confront these misconceptions. We report on a study with students in a conceptual physics laboratory investigating pulley systems using physical or virtual manipulatives. Written materials guided students through a sequence of activities designed to scaffold their model construction process. The activity sequences facilitated students' sense making by requiring them to make predictions about different pulley systems and testing these predictions by building and comparing different systems. At the end of each of the two weeks of the activity, students were given the task of designing the best pulley system for lifting a piano. We investigate the ways in which students use the manipulatives while navigating scaffolding activities and how the students' mental model development of pulley systems compares between the physical and virtual treatments.

Abstract:
|
Physics education research suggests that students' beliefs in their ability to complete physics tasks successfully--that is, their physics self-efficacy--may play an important role in explaining their learning and success in undergraduate physics classrooms (Fencl & Scheel, 2005; Kost, Pollock, Finkelstein 2005). Following this line of research, we introduce a new self-efficacy construct, Peer Instruction Self-Efficacy (PISE), which describes students' beliefs in their abilities to engage in specific Peer Instruction activities. For example, PISE includes physics students' beliefs that they can successfully convince their neighbors of the validity of their responses to conceptually based questions during Peer Instruction. In this talk, we will introduce our instrument for measuring PISE, as well as data on how students' PISE changes over the course of one semester of an introductory undergraduate electricity and magnetism course at one major research university. We will also report initial findings about the relationship between students' PISE and their eventual learning outcomes in the course.

Abstract:
|
As part of a larger research study, we focus on the investigation of barriers to instructional change. One significant barrier that has emerged is that neither faculty nor their institutions know how to evaluate student learning (or teaching effectiveness) in introductory physics courses. In this talk, we will present results from telephone interviews with 70 physics faculty related to how faculty and their institutions evaluate teaching effectiveness. We will focus on the following research questions: 1) What information is gathered about instructors? teaching and students? learning? 2) How is this information used? 3) How are different sources of information perceived or valued by faculty? Helping faculty (and possibly institutions) make judgments about whether their instruction is working may be an integral part of supporting efforts to improve undergraduate physics instruction.

We present data comparing an inquiry-based, algebra-based introductory physics course to courses taught traditionally and by interactive engagement. The inquiry-based course was taught in a hands-on, laboratory-based classroom. It was taught without a text, using materials developed explicitly for the algebra-based population, supported by two NSF grants.(1) We present data both from conceptual inventories and written pre- and post-tests administered to all of the classes.

Abstract:
|
"Troubleshooting Tasks" require students to detect an error in a statement describing a situation, explain it, and correct it. Such tasks can serve as a context for refining interpretations of scientific concepts if designed appropriately. In particular, statements should include mistaken reasoning reflecting alternative conceptions known from the research literature, and feedback should highlight how a mistaken interpretation differs from the scientific one. "Troubleshooting Tasks" were presented in an in-service program for high school teachers from the Arab sector in Israel. We report how these tasks were implemented in the classrooms. Data sources consist of statements and sample solutions composed by the teachers, teachers' assessment of students' performance, and their reflections regarding their experience. In particular, we answer: To what extent did actual implementation confirm with the aforementioned guidelines? What challenges did teachers face when implementing these tasks? The results can inform the design of in-service programs presenting teachers with similar tasks.

Abstract:

This session will address the question: What are learning progressions (LPs) and how can they be used in the classroom to determine the "next steps" for instruction? Several hands-on activities will illustrate how classroom teachers can use science LPs to: (1) evaluate the scope of current assessments across the year; (2) plan curriculum sequences using research-based learning continua; and (3) use ongoing assessment data to monitor student progress. Examples of how teachers in several states are designing assessments to determine where students are along the continuum of learning using LPS will be shared.

Abstract:
|
To improve conceptual learning, the Paradigms in Physics program has reordered material from the subdisciplines and incorporated modern pedagogical strategies. In the quantum part of our curriculum, we adopt a "spins-first" approach by introducing quantum mechanics through the analysis of sequential Stern-Gerlach spin measurements. The aims of the spins-first approach are: (1) To immerse students in the inherently quantum mechanical aspects of physics, and (2) To give students experience with the mechanics of quantum mechanics in the forms of Dirac and matrix notation. To facilitate our spins-first approach, we use Stern-Gerlach simulation software to study measurements, interferometers, spin precession in a magnetic field, and "which-path" detection. We build upon the spins-first approach by using the spin-1/2 example to introduce perturbation theory, the addition of angular momentum, and identical particles. We use Dirac notation and matrix notation throughout our five quantum courses, emphasizing the importance of fluency in multiple representations.

Abstract:
|
Efforts have been under way for many years to introduce active engagement strategies in the teaching of introductory physics. More recently there have been attempts to expand the use of active engagement into upper-division physics courses. In this talk I will discuss my efforts to employ active engagement in an upper-level quantum mechanics course, using a series of tutorial activities covering many of the standard topics in quantum mechanics. I will discuss some of the challenges of using active engagement to teach quantum mechanics, as well as my process for creating the tutorials, most of which were simply adapted from the derivations and sample problems that I had previously presented in lecture format. In addition, I will comment on the overall success of this approach, mention some topics for which I still make use of traditional lecture, and share the reactions of my students to the tutorials and the class as a whole. The tutorials (in pdf and LaTeX format) can be found at http://facultyweb.berr.edu/ttimberlake/active_quantum/.

Minds-On Audio Guided Activities (MAGA) are Podcast-delivered instruction designed to engage students in all-body experiments and foster long-term conceptual learning. These Podcasts guide students through experimentation, prompt group discussion, and lead students toward connecting daily experiences with the activity. Instruction by MAGA has undergone preliminary testing in an introductory physics course at Central Michigan University. The experiment is designed according to the standard protocol of learning assessment and involves pre- and post-tests and student interviews. Topics are currently focused on mechanics and range from discovering the differences between distance and displacement to momentum to the Coriolis effect. The session will include details of the approach and a discussion of preliminary results.

Abstract:
|
In the lecture setting, clickers make the collection of student-generated input quick and easy. Though traditionally employed in conjunction with conceptual questions and peer instruction, clickers can also be used to perform statistical experiments in real time. We describe an activity that combines clickers and a simple paper prop to conduct rapid and multiple statistical experiments. The eponymously named Monty Hall problem is an excellent exercise in conditional probability for students as it has a counterintuitive solution, but the actual outcomes can be dramatically demonstrated. Here we describe the problem and its solution and then discuss the results of an in-class implementation conducted during a lecture on probability. In addition to expanding the activity to include variations on the initial problem statement, instructors can also model radioactive decay using students, clickers, and a random number generator.

Abstract:

For the past few years we have been using online simulations to help students prepare for their Introductory Physics labs. We have written online animations allowing students to simulate the lab before arriving, which, ideally, more effectively prepares students for the lab. To test whether the simulations are more effective than traditional pen-and-paper questions as pre-lab exercises, we attempted to measure the "level-of-preparedness" of our students. Using our preparedness measure, we compare the preparedness for the two forms of pre-lab exercises. A statistically significant change in "preparedness" is found with the use of online simulations over the pen-and-paper pre-labs.

For the last two years, I have been using Multimedia Learning Modules (MLM)* developed by University of Illinois at Urbana Champagne as online Pre-lecture assignments in introductory physics courses at Cal Poly Pomona. By exposing students to the key ideas of lecture prior to class, MLMs allow instructors to focus on more in-depth application of the physics concepts during class. I will discuss the impact MLMs had on student preparation for class discussion and exam performance.

Abstract:
|
Math Machines is a unique technology that establishes explicit links to mathematics and engineering within physics labs and student-focused classrooms. Students design and test free-form mathematical functions to control engineering-style physical systems and complete immediate, physical and dynamic tasks. Examples include programming a light to follow an accelerating object, programming an astronomical clock to replicate the motions of the Moon, programming motions of a platform to simulate earthquakes of arbitrary magnitude, and programming red, green, and blue lights to display oscillating colors in various combinations. Equipment is inexpensive, consisting primarily of such things as a hobby servo motor and a 3-color LED in combination with a SensoDAQ or NI myDAQ computer interface. Schools are encouraged to build similar equipment and share it with math, science, engineering and technology teachers in their region.

Abstract:
|
Students in introductory physics often need significant support to develop the thought processes to be successful in physics. A TabletPC, similar to a SMART Board, can be used to create screencasts (videos) of worked out problems or even complete problem-solving sessions. If the instructor records the audio with the writing, students can watch the videos or replay parts they don't understand. The TabletPC can also be used to record Interactive Lecture Demonstration (ILD) results using the screen capture function or screencasts of complete video analysis demonstrations. Since ILDs particularly focus on helping students develop concepts, these videos are effective reinforcements for what occurs during the ILD in class.

Abstract:
|
We present the rationale and results driving Florida International University's (FIU's) new physics teacher preparation program, a program designed to cultivate success for all students. FIU implemented yhe University of Colorado's Learning Assistant (LA) model in 2008 through a PhysTEC Grant. The LA model is an experiential teaching program for undergraduates that recruits and prepares future teachers while driving departmental reform, as LAs must experience research-validated curricula in order to make informed decisions about their future in teaching. The program now supports 45 LAs, impacts over 2,000 introductory physics students per year, and is now fully sustained by department funding. The LA program's success has prompted a spread to chemistry, earth science, mathematics, and biology. The impact is most compelling as FIU is a minority-serving urban public research institution in Miami, serving over 42,000 students, of which 64% are Hispanic, 13% are black, and 56% are women.

Brigham Young University restructured the physics teaching program in 2004. Since that time, this year we will reach our 100th physics-certified teacher. The highlights and heartaches of this program will be discussed. The efforts of the College of Math and Physical Science to bring the Physics Teaching Program back to the Department of Physics and the support this came with from the College of Education will be discussed. The working relationships between the two colleges and the local school districts will be shared. How we fund a teacher in residence and the value of the mentor teacher network to develop our students as teachers will be highlighted as one of the strengths of the program. We will also share the efforts that are made with mentoring and induction of new physics teachers as part of this talk.

We present the results of a cogenerative teaching experience in an elementary science content and methods course. This course implemented the Physics and Everyday Thinking (PET) curriculum, which we adapted to meet student and programmatic needs. In this talk we will discuss the cogenerative mediation process for learning environments (CMPLE) by which those adaptations occurred. Implementing CMPLE helped us to identify the needed course changes and effective teaching practices for this student population. Having done so was worthwhile, and provided us with a valued experience.

We present the results of a cogenerative teaching experience in an elementary science content and methods course. This course implemented the Physics and Everyday Thinking (PET) curriculum, which we adapted to meet student and programmatic needs. In this talk we will be discussing a specific adaptation we made to the PET curriculum. This change was achieved by uncovering the students' needs using the Cogenerative Mediation Process for Learning Environments (CMPLE) and then creating an extension from the infrared portion of the PET curriculum. This extension connected PET and physics in general to biological concepts. This extension was a result of cogenerative discussion regarding the needs of the students.

Abstract:
|
Physics education is an essential part of science education. Physical and biological sciences should be introduced to young students as early as possible in elementary schools and kindergardens. Then physical science will be divided into physics, chemistry, astronomy, geology, etc. in senior high schools. Later, at the college/university level, they are sharply divided as different fields and highly specialized to particular topics. For high school teachers-to-be, it is challenging to teach with some areas combined at high school level due to the sharp specialization at college studies. How do we help new teachers apply physics laws to chemical, geological, and biological processes. And above all, how to apply physics laws to environmental issues. This task is for both teachers, high school and college levels.

VCalc is an RPN vector calculator for the iPhone/iPod designed to help in performing various vector-intensive computations on a portable device. VCalc was created out of a need to perform vector calcuations like those required in intro physics courses, particularly the great "Matter and Interactions" curriculum developed by Ruth Chabay and Bruce Sherwood. This talk is a "behind the scenes" view of the development of an iPhone application intended for student use and the likely potentialities and limitations of such an approach. Alternative approaches and related apps are also discussed.

Abstract:
|
Clickers are a powerful tool for classroom instruction, but like any tool, they may be used skillfully or clumsily, for more or less fruitful purposes. What purposes are fruitful? Why do some teachers give up, some muddle along, some succeed, and some entirely transform their teaching? Based on personal teaching experiences, mentoring of others, and several years of research with teachers learning to use clickers, we offer some hard-won answers to these questions. Clicker use is best aimed at supporting question-driven instruction, dialogical discourse, formative assessment, and meta-level communication in the classroom. How teachers *frame* classroom activity -- their deeper attitudes, models, and professional thought habits -- is the most important factor determining their results. Explicit, concrete yet flexible "question design patterns" for creating clicker questions and "pedagogical patterns" for using them in class help teachers avoid common traps, get unstuck from ruts, and take full advantage of clickers' potential.

It's really hard to believe but, I've never taught a physics lab without using some sort of computer interfacing equipment. As a 25-year veteran teacher, doing labs with Vernier data-collection technology has been a career-long process. In my small college setting, I can have students do very traditional problem solving labs, PER-Activity Based Labs or I can even have them create their own student designed and driven experiment. Computer Interfaced Lab Equipment has enhanced and supplemented my lab activities for the past 25 years. This talk will discuss the origins, the changes, the advancements and what I now consider the best practices for using computer technology in the introductory physics laboratory.

Abstract:
|
Students in introductory-level physics encounter several difficulties when solving physics problems involving differentiation and integration. Physics instructors tend to assume that students have the prerequisite mathematical skills for success in the course, however, research has shown that most students do not know how to apply mathematical tools in a physics context. Based on the knowledge of the difficulties students with the use of differentiation and integration in physics encoutered from previous studies, we are developing instructional materials aimed at facilitating students to address these difficulties in several topics in introductory physics. We have implemented these materials in group problem-solving sessions aimed at enabling students to learn the mathematical concepts of tangent lines, slope, Riemann sum, and approximation in a physics context. We present a discussion about student difficulties on those concepts and the development of our instructional materials.

Abstract:

We consider physics problems that require students to combine their existing resources in new ways. When students do this in the context of integration and differentiation, they have many procedures, concepts, and representations to choose from. In addition, they may have varying degrees of understanding about the procedures they invent. We examine students' resource selection in problem solving situations, using an online environment to control and monitor their progress through a series of hints. Over the course of a 30-minute testing period, students work through a single problem; initially inventing their own strategies, then following our suggestions toward particular solutions. We will present results from our assessment of students' naïve understanding, as well as the impact of cues and training after a 50-minute practice session prior to the test. We will also describe students' ability to learn new ways of thinking about the problem.

Abstract:
|
Many researchers and textbooks have promoted the use of rigid prescribed strategies for encouraging development of expert-like problem-solving behavior in novice students. The UBC Physics 100 course has been using context-rich problems with a prescribed five-step strategy since 2007. We have been analyzing audio recordings of students during group problem-solving sessions to analyze students' epistemological framing based on the implicit goal of their discussions. By treating the goal of "understanding the physics situation" as "sensemaking," we analyze the effectiveness of structured prompts intended to promote a shift to a sensemaking discussion. This talk will describe the setting and research methods, and a subsequent talk will discuss the analysis and results.

This study focused on the effect of varying the sequence of problem solving and laboratory activities on the students' ability to solve subsequent biomedical contextual physics problems. A series of laboratory and problem solving activities were designed using concrete physical situations. Following the introduction of specific physics concepts, students worked in groups to complete related laboratories and problem solving activities. The order of problem solving and laboratory activities was regularly altered throughout the semester. Subsequently, the students were asked to solve related contextual biomedical physics problems. The result of the study indicated that altering the sequence of activities had a measurable impact on students' contextual problem solving performance and strategies.

Abstract:
|
It is well known that transfer from worked examples to new problems can be very hard for students. The goal of this research is to promote transfer by improving the quality of the example solution. According to our experience, elaborate verbal explanation often seems to have little, if not negative, effects on transfer. Therefore, we focus on designing a better visual representation. Based on knowledge from grounded cognition research, we designed several animated multimedia solutions for some difficult physics problems, in which the underlying logic is illustrated through visual perception. When compared to two other very similar versions of animated solutions that lack the critical perceptual elements, the designed solutions significantly improved transfer of the underlying physics principles to harder problems. Moreover, transfer is improved even when the target problem involves largely abstract logical reasoning, and little visual-spatial reasoning.

Abstract:
|
Item Response Theory is a useful tool for analyzing quantitative data. The sample size will impact the uncertainty of the estimated parameters. It is then important to find out the approximate minimum sample size, with which reliable results can be calculated. In this study, we choose R (with its LTM package) to estimate the parameters with different sample sizes, which are randomly selected from the college students' FCI data collected at The Ohio State University. The total number of the data is 3139. The results show an exponential relationship between sample size and the mean difference of the results obtained with subsets of the data. When sample size is larger than 1600, the difference is tolerable for most items and the mean total difference can be controlled within 5%. This can provide useful guide for future data analysis using IRT.

Abstract:
|
We developed a web-based tool to provide students with access to old exam problems and solutions. By controlling the order in which students saw the problems, as well as their access to solutions, we obtained data about student learning by studying old exams problems. Our data suggest that in general students learn from doing old exam problems, and that having access to the problem solutions increases their learning. However, the data also suggest the depth of learning may be relatively shallow. In addition, the data show that doing old exam problems provides impor-tant formative assessment about the student's overall preparedness for the exam, and their particular areas of strength and weakness.

Abstract:
|
The Physics Education Group at the University of Minnesota has been developing Internet physics coaches to help students improve their problem-solving skills in introductory physics. In this talk, we analyze keystroke data collected from students' usage of the computer programs, including the identity and timing information for all students' keystrokes and mouse clicks while using the programs, as well as derived information such as the average time spent on each module. We use the data to try to determine how students use the computer programs, where they might have the most difficulty, and details of their decision-making behavior during the problem-solving process. Other data sources such as students' written solutions will be used as a consistency check.

From three years developing over 400 physics applications from the NY Times I will show the best applications rich in data verifying physics concepts. Most applications are on mechanical concepts. The site is: http://CisePhysics.homestead.com/files/NYT.htm. The site lists 12 pages with 40 single one page applications per page. Each single page application contains: brief edited text and graphics from the NY Times, introduction,questions,hints, and answers. I use these pages as: introduction to new concepts in general college physics, extra credit for students, and quiz questions. Students enjoy verifying physics concepts using NY Times current physics applications as seen at this site: http://CisePhysics.homestead.com/files/NYT.htm

Abstract:
|
Einstein's Dreams by physicist/author Alan Lightman has for years been a popular selection for high school and college summer reading programs and for student presentations as narrative theater. The book describes a number of "dreams" that the young Swiss patent clerk Albert Einstein might have had during the "miracle year" of 1905. While the dream narratives can be read for their entertainment value by people with little knowledge of physics, any physicist reading them will find numerous references to relativity theory, quantum theory, thermodynamics and cosmology. A few of the dreams also reflect aspects of physics student culture and quips that Einstein is believed to have made. These references can be used for teaching and to demonstrate the creative element in physics, which clearly bridges C. P. Snow's two cultures or the alleged left brain/right brain duality. It provides an opening for interaction with literature and history teachers as well. The presentation will discuss a number of the "dreams" and their allusions to physics, and will provide some suggestions for further reading.

In a Sherlock Holmes adventure "The Sign of Four" the culmination is the race along the Thames. The relative speeds could be analyzed to discuss the possibility and feasibility of this part of the story. Also a discussion of projectile motion could be made from the data mined from Sir Arthur's description. The exercise is well within the grasp of introductory physics students.

Abstract:

Once upon a time your students' imaginations and curiosity were unleashed through the fantasy of their first picture books. We can recapture some of that excitement if we reopen the classic books and allow them to guide us as we explore the real world in our high school classes. Let us examine some new examples of how children's books can model science processes, lead to science investigations and even act as assessment. This paper is follow-up to the "Seuss Science" presentation given at the Portland Summer Meeting. Additional books not mentioned in that paper will be used.

Physics is Phun! Physics needs everyone and everyone needs physics! With physics, the UNIVERSE is the limit! These statements are the underlying principles that we, the physics faculty at Morehouse College, embed in our students through experiences in the classroom, laboratory, advisement, mentoring, and outreach programs. How are we making a positive difference by consistently increasing the number of under-represented minorities, especially African American males, in physics? We will present our antidote which includes curriculum, research, advisement, and a few hidden ingredients.

The Timbuktu Academy is a comprehensive, systemic mentoring program at Southern University and A&M College in Baton Rouge, LA (SUBR) (www.phys.subr.edu/timbuktu.htm). To date, the Academy has assisted in the production of 170 minority undergraduate scholars who have earned a Bachelor of Science degree. Seventy of 83 physics graduates, 20 of 29 chemistry graduates, and 22 of 49 engineering graduates have earned graduate degrees or are successfully enrolled in graduate school, with an emphasis on the pursuit of the PhD. The aim of this presentation is to discuss key factors that explain the success of the Academy. They include the rigorous implementation of the Ten-Strand Systemic Mentoring model of the Timbuktu Academy, with extensive research participation on and off campus. They also include standard-based curriculum, teaching, and learning (i.e., SBC, SBT, and SBL). The Timbuktu Academy received several national awards for the above model and results.

Abstract:

Physics provides a fundamental foundation for nearly all major technical innovations, groundbreaking research, and policy recommendations. Physics also ranks at the bottom when considering the fraction of students completing either baccalaureate or doctoral degrees. In addition, the fraction of PhDs awarded to underrepresented minorities has not increased in the past decade despite the growing population of such groups. This talk will discuss some data on the current situation and describe a number of actions by the American Physical Society (APS) and its partnering organizations in addressing these issues, primarily the Minority Bridge Program, a new national initiative that seeks to dramatically increase the number of underrepresented minorities who receive PhDs in physics.

Abstract:
|
John Archibald Wheeler was a radical conservative: Take the laws of physics seriously, then drive them to their limits. He drove general relativity to its limits with the black hole, our "little jugged apocalypse." Wheeler's Rules of Writing include "Simplify! Simplify! Simplify!" For undergraduate general relativity this means (1) Describe curved spacetime with the metric instead of the field equations, which reduces required mathematics to simple calculus. (2) Command the moving stone to obey the Principle of Maximal Aging, a simple extension of the Twin "Paradox." A second edition of Exploring Black Holes with cosmologist Edmund Bertschinger treats the wealth of recent cosmological observations and repairs the first edition's neglect of the dark side of General Covariance: We can choose global coordinates with (almost) complete freedom, so they need have no direct relation to physical measurements and observations.

Special relativity for the nonscience student: In an introductory freshman seminar course “Einstein for Everyone” Yes! We know that the physics of special relativity does not require mathematics beyond high school trigonometry, but how often do we offer nonscientists the chance to explore the intuitive and nonintuitive implications of the ideas at the core of spacetime physics? Using one course as an example, we will explore questions of its depth of coverage and its role in the curriculum. This will include examples of sample assignments, student projects as well as simulations that stand at the heart of the course and serve as the course "laboratory."

Abstract:

In my experience, successfully teaching special relativity to introductory students is much easier if one extensively uses (1) the geometric analogy for spacetime, and (2) visual aids based on that analogy, including (but not limited to) multiple-observer spacetime diagrams. In this presentation, I will describe some of these visual aids and how such tools can help students reason more intuitively about relativity and thus avoid many common errors and misconceptions, and describe resources one can use in special relativity courses at any level.

Abstract:
|
A large demand for energy in Pennsylvania is for space heating. Unfortunately, this demand coincides with low winter solar insolence making traditional solar thermal energy impractical for space heating. However it is possible to collect this solar energy in the summer and to store it for later use in the winter using a seasonal thermal energy storage system (STES). Existing STES systems have had a variety of problems due to cost, thermal losses, and/or slow thermal time constants of the storage field. This research has focused on designing and locating a potential site for a solar STES system using an abandoned coal mine that solves many of these problems. The design, dynamic simulation, and estimated performance of such a system will be presented. Construction estimates and return on investment will also be presented for a potential site in which a favorable abandoned mine has been found very close to a K-12 school.

Abstract:

From the dawn of civilization, energy density and power density has been sought and fought after. This talk will walk through the foundation civilization has built for ourselves throughout the technological and nontechnological world and compare it to how nature has evolved. We will ponder if economics has broken a historical global symmetry by making the lowest energy state not the preferable state and ask ourselves why? Ten interactive Societal Ragone Plots will be presented and passed out: from vehicles to robots to hummingbirds. Results from an agent-based model of African electricity microgrids will be presented and juxtaposed to policy implications in the U.S. for our centralized grid with and without nuclear power. Monte-carlo simulation results for a designed U.S. military forward operating base in Afghanistan will be presented to discuss the risk that explains an amazing quote that "the U.S. loses one person, killed or wounded, for every 24 fuel convoys it runs in Afghanistan to run air-conditioners and power diesel generators." Energy and power density engages with society -- from African health care to U.S. military risk to everyday U.S. civilian activities.

Having consulted a broad sweep of educators teaching about energy for several years for EnergyTeachers.org, Mr. Reeves will comment on the integration of energy curriculum into the physics curriculum as well as the possibility of energy becoming its own field to rival the importance of physics. Learning new and even traditional energy concepts presents a challenge in the world of standardized or traditional curriculum, especially concerning sequence and rigor. Textbooks, professional development, lesson plans, field experiences, workforce training, and academic pathways need to be developed further. The content and structure of EnergyTeachers.org represents the wide range of answers to such challenges for K-16 and informal educators, but there is much work to be done. What role will physics educators have in this work?

Because they are used carelessly and indiscriminately, the words "sustainable" and "sustainability" have lost their meaning. The reasons for this loss of meaning range from simple carelessness to commercial greed. The ultimate contradiction is the oxymoron "sustainable growth." We will examine the definition of "sustainability" and then will look at what it has to mean in terms of growth, population, and the extraction of mineral and fuel resources from the Earth.

New physics teachers need mentoring! In addition to the need to know and understand their content, they need direction deciding upon appropriate demonstrations, analogies, examples, and labs, pacing of topics, seniors in the spring, classroom management, lab supply budgets, and much more. This talk will explore the role that mentors play in attracting new physics teachers, in helping them through those critical first years, and in retaining them in the profession. As a former mentee, I can speak to the value of all of these.

As I near retirement I am beginning to panic. Who will take my place? Will they care as much as I do? Will teaching be their passion not just a job? With the diminishing number of science teachers entering the "pool" and even fewer in physics, what can veteran teachers of science do to encourage beginning teachers to enter the profession and remain in the profession when the going gets tough?

Abstract:
|
Mentoring from a master teacher during student teaching may be the most important semester in the preparation of a new teacher. But even this mentoring does not prepare a student for what happens during the first year when they have a classroom full of their own students. I want to follow the story of two students who without induction after they graduated most likely would not be teaching now. Retention of these new teachers is as important as training new teachers. I think our role in helping with the mentoring and induction of these new teachers is as important and on par with the efforts that we make to help these students get their teaching licenses. I know these students have graduated from our teacher preparation programs but they still need to see that friendly face, hear that friendly voice. These students just need to know you as their teacher preparation mentor are still there and care.
I will try to show how I think that the two students I have talked about above may not be teaching if they had not been confident that a university mentor would help.

Abstract:

In this talk I will describe how the Rutgers Physics Teacher Preparation program connects pre-service training to post-graduation professional development and practice. The key here is to use social networks and face-to-face meetings as two components of a professional learning community. I will show how one can maintain such a community with very little time investment and no additional funding. The learning community not only supports beginning teachers during their most difficult years of teaching but also allows pre-service teachers to have high quality student teaching experience. I will share the achievements of the community and the difficulties that arise. Rutgers has been producing large numbers of physics teachers for the past eight years. Over 90% of these teachers remain in the profession.

Abstract:
|
Brigham Young University's "15-Week University" course brought together students and faculty with diverse backgrounds and wide-ranging ability to experiment with learning principles as they applied to physics, calculus, English, and music. The challenge was to explore core ideas with enough depth and rigor to ensure that gains in learning could be retained, improved, and applied for long-term growth. A learning community emerged as everyone became a learner and teacher engaged in: 1) identifying key elements and core ideas, 2) maximizing resources through innovative use of technology, and 3) solving challenging problems that connected fundamental pinciples to concrete skills and personal values. Results included substantial (in some cases dramatic) increases in quantitative skills and writing ability, and enthusiasm for learning in general. The synergy of this wide-ranging learning experience happened as participants rotated their teacher/learner roles, connected ideas and information, and reframed their knowledge from multiple perspectives.

Abstract:
|
The 15-Week U was an experience of re-imagining classroom relationships, content, and time. Rather than treating the inevitable spread in ability and background as a hindrance, this class emphasized and heightened the differences by shifting learner and teacher roles. Teachers from the various disciplines of the course became model learners as the topics shifted. Students with certain strengths became teachers as the course emphasis changed. Such shifts created a rich source of individualized input for every member of the community and multiplied the sources of energy and motivation for learning. The interdisciplinary nature of the course meant that content was viewed from multiple perspectives. Rather than dilute content, this framework intensified both quantitative and non-quantitative thinking. Students with little science background made surprising leaps forward in their engagement and competence, and students with a stronger background consolidated the magnified their grasp of skills and subject matter.

Abstract:
|
The Physics of Theatre project was started to address a clear need within the theatrical community for better understanding of physics concepts in order to design and build increasingly more complex and potentially dangerous equipment safely and efficiently. My efforts within the project are in two main areas: 1) experimentally studying the properties of materials commonly used in theatre and 2) educating theatre technicians about the principles of physics through lectures, workshops, and the development of pedagogical materials. Through this project, we have developed lecture materials and labs that I use in both introductory and advanced undergraduate classes. I have also been able to expand my research interests into areas which are accessible to undergraduates as early as their sophomore year. The physics in these projects is not particularly advanced, but students can develop a much deeper understanding of what they did and have true ownership of their projects.

Abstract:
|
Traditionally, introductory physics courses require a good handling of mathematical manipulations. Many students come to college with a desire to learn physics, and they say that they like it. But when they take college physics they find the mathematics involved in it challenging. However their desire to do well is not enough sometimes to solve problems. Many students have a good feeling for the concepts and like laboratory experiments. In an introductory physics class at a small college, the student population is very diverse in background and expectations. Talking with my colleagues from other disciplines I learn about their type of assignments, and I offered my students choices. I will present different types of choices for in class and at home assignments.

Abstract:
|
The physics education research literature provides a wealth of information on active-learning procedures, such as interactive lecture demonstrations (ILDs), peer instruction facilitated with clickers, or tutorial systems. However, much of this material has been focused on their use in courses that cover the canon of topics, such as introductory physics courses designed for science majors or conceptual physics courses. Courses that investigate the connections between physics and music are common in physics department course offerings for general education purposes, and they provide an important opportunity to instruct students who may not otherwise take a course in the field. A suite of these tools has been developed for a course on physics and music. Discussion will include clicker ILDs, clicker questions, and lab-based activities, all designed to enhance the learning of students in topics such as motion, oscillations and waves, and sound.

Abstract:

Columbia College offers an introductory, algebra-based mechanics course called "Physics for Filmmakers." The course is for students who wish to learn how to use the laws of physics in making more accurate and/or artistically deliberate choices in their filmmaking. We debunk common movie errors and misconceptions, and students must also complete a film project that demonstrates correct physics in some way. In this talk, I will discuss how we use Tracker (http://www.cabrillo.edu/~dbrown/tracker/) in our labs to teach both filming ideas and physics concepts, some final film projects we have seen, and how we use PER-influenced ideas to further support our learning goals.

The College of Idaho (C of I), located in Caldwell, ID, runs a cooperative summer program with Syringa Middle School (Caldwell, ID). This program, titled The C of I/Syringa Math and Science Summer Institute (MSSI), is now in its third year. MSSI is an educational enrichment program for Caldwell 7th and 8th grade students that specifically targets students who demonstrate potential for academic success but who are at risk for dropping out of school. The MSSI provides enrichment activities in science/engineering with a strong mathematical component. The 8th grade students spend the week-long program studying near-Earth asteroids and probability. The students discover what types of asteroids pose a risk to civilization, and apply their knowledge of probability to determine whether civilization is, indeed, at risk. This talk will focus on the misconceptions MSSI students have about probability and asteroid collisions, as well as the benefits of a summer enrichment program for these students.

The University of West Georgia has acquired several astronomical cameras and guided telescopes to accommodate an increasing number of introductory astronomy students and projects that are being conducted by students. This equipment was purchased using local Tech Fee grants. Beginning in the fall semester 2010, honors astronomy students are required to image two celestial objects and to process those images. A majority of these students are non-science majors. Students are given a CD with their images and the images made by their classmates. During the first two semesters of this requirement, the images made by students are excellent, and the student attitudes about the work are positive.

Abstract:
|
General-studies science classes at many universities, such as physical science, earth science, or astronomy, stress memorization and repetition of concepts. This approach leaves students with little appreciation for how science is used to explain phenomena from general principles. We present a novel instructional technique for an earth science class in which the students are instructed in the use of a general problem-solving strategy, adapted from well-known quantitative problem-solving strategies, in order to train the students in how to apply physical principles. Preliminary data using the Epistemological Beliefs Assessment for Physical Science has shown that explicit training in problem solving significantly improves students' epistemology.

Abstract:
|
Introductory astronomy courses are among the most popular science courses taken by non-science majors in college. As a result, these courses represent a crucial opportunity to educate students about the nature of science. I have developed two courses that focus on teaching the nature of science through an exploration of the history of astronomy. One course examines the development of planetary astronomy from Aristotle to Isaac Newton. The other course follows changing notions about our place among the stars from Aristotle to Hubble. In both courses, students make frequent use of computer programs to simulate observations and to visualize theories. The goal of these activities is to help students see how scientific theories are judged against empirical data, consistency with other knowledge, and aesthetic criteria. Course materials are available at http://facultyweb.berry.edu/ttimberlake/copernican/ and http://facultyweb.berry.edu/ttimberlake/galaxies/.

Abstract:
|
One can become almost incoherent trying to remember how we taught physics without the laser. In April 1963 the first issue of The Physics Teacher appeared, and the journal soon began to carry seductive advertisements for lasers showing how the physics teacher could use this wonderful new device in the lecture room and the laboratory. Two years later the Kenyon College physics department paid $1,650 for a relatively short-lived laser, and I was hooked. In this talk I will use advertisements from TPT to show how the prices decreased and our expertise in using the laser increased. Soon it became as indispensible to teaching physics as a multimeter or a meter stick.

Abstract:

Laser safety is not always given the attention it might warrant. When one evaluates the level of laser safety required, using a laser pointer is substantially different than aligning a Class 4 laser. This presentation will emphasize basic laser safety when using Class 3B or Class 4 lasers in a university setting but could easily be applied to any similar facility or classroom environment. Laser safety information presented and practices described will be in accordance with the American National Standard for Safe Use of Lasers (ANSI Z136.1 - 2007) and CLSOs' Best Practices in Laser Safety (Laser Institute of America - 2008).

Abstract:
|
Physics students are expected to apply the mathematics learned in their mathematics courses to physics concepts and problems. Few PER studies have distinguished between difficulties students have with physics concepts and those with either mathematics concepts, application of those concepts, or the representations used to connect the math and the physics. We are conducting empirical studies of student responses to mathematics questions dealing with graphical representations of (single-variable) integration. Reasoning in written responses could roughly be put into three major categories related to particular features of the graphs: area under the curve, position of the function, and shape of the curve. In subsequent individual interviews, we varied representational features to explore the depth and breadth of the contextual nature of student reasoning, with an emphasis on negative integrals. Results suggest an incomplete understanding of the criteria that determine the sign of a definite integral.

Abstract:
|
The Force Concept Inventory (FCI) has deservedly become a widely accepted assessment tool. The metric "normalized gain" can be used to evaluate conceptual mastery in a high school, college, or university-level mechanics course. Left out of this analysis, however, is student mastery of other physics concepts typically presented in the same course. For example, conservation of energy and momentum, as well as rotational motion, receive virtually no coverage on the FCI (or, for that matter, the Mechanics Baseline Test). The authors will present a revised assessment tool, one that incorporates the strengths of the FCI, but also assesses these other mechanics-related concepts. Our tool will preserve the straightforward multiple-choice format of the FCI. Ten additional questions have been written, in part inspired by material from the Physics Education Group at the University of Washington and in part inspired by the authors' own experiences with common student misperceptions.

Using computer technology, we develop a virtual reality (VR) platform that supports interactive physics activities. We use the platform to help students conduct guided explorations to learning physics concepts and reasoning. A teaching experiment with two random selected groups of students was conducted. Students were asked to complete a one-hour exploration on one dimensional motion (1D motion) and circular motion. Using a cross-controlled design, we find that students doing virtual experiments outperform their peers doing paper-based problem solving.

Abstract:

Common research methodology uses research tasks that ask students to identify a correct answer and justify their answer choice. We propose expanding the array of research tasks to access different knowledge that students might have. By asking students to discuss answers they may not have chosen naturally, we can investigate students' abilities to explain something that is already established or to disprove an incorrect response. The results of these research tasks also provide us with information about how students' responses vary across the different tasks. We discuss three underused question types and their possible benefits. Additionally, we present results from data gathered using these question types and contrast these with results gathered using a traditional question.

Abstract:

Students working through the Intermediate Mechanics Tutorials on damped harmonic motion are expected to use mathematical, graphical, and physical reasoning, as well as their intuitions. We observe that students remain committed to assumptions they bring to the problem, not using the instructional resources provided by the tutorials. We also observe moments when commitment to an assumption in, for example, mathematical reasoning conflicts with a conclusion found through physical reasoning. We will discuss the effect of multiple commitments on students' classroom discussion and the way that students reconcile contradictory commitments and conclusions.

Abstract:
|
While investigating the impact of interactive learning strategies on pre-service elementary science teachers, we devised open-ended content questions focusing on the application of learned concepts to new contexts. We designed a protocol to evaluate students' responses through different lenses. First, we classified concepts into three types: descriptive, hypothetical, and theoretical [1], and categorized the level of abstraction of the responses in terms of the types of concepts and the links between them [2]. Second, we devised a rubric based on Bloom's revised taxonomy [3] with seven traits (both knowledge types and cognitive processes) and a defined set of criteria to evaluate each trait. Looking at the same responses with both lenses we can investigate the correlation between the level of abstraction and the sophistication of students' reasoning as indicated by the traits of our rubric.

Abstract:
|
It has long been known that a students' entering mathematical skill level is one of the best indicators of success in introductory physics courses.[1, 2] Physics teachers expect that students who meet the prerequisite requirement of an introductory physics course will be well-prepared, however, this is not always the case. In reality, every physics teacher faces the challenging question: Can we identify and save the students who meet the required course prerequisite yet who are not really prepared? A recent study at the Department of Physics and Astronomy at Eastern Kentucky University suggests that when students take physics, their mathematical skills improve significantly, perhaps even more so than they do in a traditional mathematics course. This work will focus on the analysis of what mathematical skills have been improved, and reveal the link between the course content and mathematical skill improvement.

Abstract:

Sampling is an important scientific reasoning ability frequently used in experimental design and data interpretation. As part of the research on assessment of students' scientific reasoning skills, we designed a series of multiple-choice instruments that probe students' understanding of the concept of sampling. The assessment was carried out among the students from grade four to grade 11 to study the development of students' understanding about sampling which was involved in the scientific context. Results from students at different grade levels indicated that students did not understand and consider the concept of sampling as a significant scientific reasoning skill until grade eight.

Abstract:
|
The PhET Interactive Simulations project is a collection of more than 100 simulations of physical phenomena that create animated, interactive, game-like environments in which students learn through scientist-like exploration. While the sims are designed and tested with introductory college-level courses, anecdotal data from middle school teachers suggested that PhET sims could be used effectively with fifth-eighth graders -- with teachers citing the intuitive controls and engaging, game-like style. These reports motivated us to study how sims can be best designed for and used in middle schools more systematically. We have conducted numerous interviews with middle school students using PhET sims, and collected video and observational data from middle school classes using sims. We will present our findings from these studies, including effective design principles for middle school sims, insights into how middle school students learn from sims, and benefits of and challenges to using sim-based activities in middle school classes.

Abstract:

We describe the open-source library of physics problems we are collecting in LON-CAPA (http://loncapa.mit.edu). Currently, the library features both traditional and research-based problems intended to expose students to various contexts, problem features, knowledge and cognitive processes. We are adding conceptual questions and challenge problems that require out-of-the-box thinking. The conceptual questions were developed at Ohio State University and MIT. The challenge problems are inspired by various tasks published in The Physics Teacher. 1-3] We are planning to evaluate the difficulty and pedagogical effectiveness of those problems using Item Response Theory (IRT). This permits determination of a student's skill independent of which problems they do. We welcome collaborators willing to add their problems to our library.

Abstract:

We present the first evaluation of our open-source Integrated Learning Environment for Mechanics (ILEM)[1] - http://loncapa.mit.edu. The centerpiece of this environment is a collection of multi-level research-based homework sets organized by topic and cognitive complexity, whose design helps students learn physics problem solving. These sets are associated with learning modules that contain short expositions of the content supplemented by integrated open-access videos, worked examples, simulations, and tutorials. In our evaluation of homework problems, we analyze student attempts, preferences, and performance on different types of problems (e.g. representation, ranking and strategy writing problems). In our evaluation of content, we analyze observations generated by student comments in the discussion boards and during critical thinking activities. We continue to expand and improve the content and we welcome users and collaborators.

Abstract:
|
The ability to work with graphs is a necessary skill in all of the sciences, yet students still struggle with it. Previous graph-related problems in LON-CAPA (http://www.lon-capa.org/) required students to pick the correct graph from a set of graphs or infer data from a given graph. Data gathered from the Test of Understanding Graphics -- Kinematics (TUG-K) confirms that these problem types only minimally improve representation translation skills. A new problem type has been developed in LON-CAPA that allows students to construct (draw) graphs for themselves, in response to a given textual (or formulaic) description. These graphs are then checked by the server, which determines whether or not the student submitted graph is correct or incorrect. We present some preliminary experiences with this new problem type, while a study is under way to test the effectiveness of this approach.

Abstract:
|
Item Response Theory (IRT) algorithms are being developed to better assess student performance in our Integrated Learning Environment for Mechanics (ILEM; [1]). A student's skill, as determined by IRT, provides more information than the traditional student score because it takes into account universally calibrated problem difficulties. Importantly, it allows determination of skill on a universal scale independent of which questions the student answers. Our approaches seek to dynamically update student and class skill level in ILEM throughout the course based on their performance, rather than relying primarily on the gain from pre/post testing. We present results comparing IRT and pre/post gain analysis of the Mechanics Baseline Inventory Test, including discussion of item parameters for the 26 questions on the MBT exam.

Abstract:
|
Monitoring and assessing the students' learning activities before (pre-), during (in-) and after (post-) lecture teaching in a large (more than 150 students) introductory physics class are important to evaluate the efficacies of new teaching pedagogies and methods. At Texas Tech, an online and integrative computer-based approach of using an interactive pre-lecture Just-in-Time tutorial, in-lecture Peer-Instruction clickers, and post-lecture Lab and online homework was implemented in the last two semesters. Using standard mechanics concepts and baseline surveys as well as independent classroom observations, the effects of these computer-based technologies on students' learning of physics concepts and problem-solving skills among different student subgroups taught by TAs and lecturers using different levels of student interactive engagement in class are investigated. Comparisons among computer-based technology interventions and their predictive roles in learning outcomes will be examined using Pearson correlation and multivariate analysis methods.

Easy Java Simulations (EJS) is a free, open-source tool for creating interactive computer simulations. This summer (June 2011) I will be using EJS to teach 9th and 10th graders to create computer simulations in a week-long (summer science camp) course. Will we succeed? What will they create? Come find out! During the past year I have also used EJS for teaching multiple undergraduate courses in computational physics, so I will address the specific challenges and opportunities that arose when teaching high school students versus college students.

Abstract:
|
Problem-based learning (PBL) focuses on experiential learning organized around the investigation and resolution of a real-world, or "messy" problem. The problem is typically one that is closely tied to students' communities and involves stakeholders from both within and outside of a particular school building. We present several examples of how the PBL methodology has been successfully applied to secondary-level physics instruction. In these examples, students 1) investigated how to incorporate renewable energy technologies within their school district, and 2) evaluated the impacts of noise pollution upon the school environment. In PBL projects, student evaluation relies heavily upon final presentations to stakeholders, and is more authentic than traditional pencil and paper tests. Students master curricular goals while at the same time achieving deeper levels of understanding through inquiry and the exploration of multifaceted problems.

Abstract:
|
This research was conducted by an urban middle school science teacher who sought to investigate the effects of self-assessment on student performance. A group of students were asked to give themselves a score on each learning target assessed in class and to provide evidence for their decision. Student self-assessment scores were compared to scores given by the teacher to see if students who accurately assessed their own learning scored higher on final assessments than students who did not. Assessment scores between groups of students who completed the self-assessment preparation and students who did not were also analyzed. Preliminary findings will be discussed in this presentation as well as further implications for this teacher's classroom.

Abstract:
|
I used a multivariable regression to analyze success (grades) in six years of online and campus-based introductory physics classes at Chemeketa Community College. I analyzed independent variables including incoming GPA, grade in trigonometry, gender, age, home institution, and delivery method to determine their effects on success. I found that incoming GPA, home institution (Chemeketa students fared worse than outside students), and delivery method (there was an online "penalty" of about half a grade) significantly impacted success while other independent variables did not. In addition to presenting the multivariable regression analysis, I will provide both evidence of academic honesty and evidence that my students conduct substantive labs at home; these appear to be points of considerable skepticism among physics educators. I will also provide data and practices regarding retention, a challenge for any class with any delivery method at a community college.

Abstract:
|
Sonic ranger sensors have been successfully used in physics labs and play a major role in the design of reformed introductory physics classes. We have recently taken advantage of advances in the portability and ease of use of sonic rangers to develop a lab-based kinematics course delivered completely online. Following established curriculum plans utilizing progressively scaffolded interactive labs, this course uses digital data collection and analysis as the foundation of an interactive peer learning experience. Students in our online "Concepts of Force and Motion" course are required to purchase an equipment kit that includes a USB-interface motion detector and data collection and analysis software. The overwhelming success of this effort is how much students enjoy using this lab equipment at their home. Our experience is that every student has managed to overcome any initial trepidation, to complete the class with a positive reaction to both the technology and the emphasis on experimentation.

Abstract:
|
The trajectory of a baseball moving through the air is very different from the one we teach in our introductory classes in which the only force is that due to gravity. In reality, the aerodynamic drag force (which retards the motion) and the Magnus force on a spinning baseball (which causes the ball to curve) play very important roles that are crucial to many of the subtleties of the game. These forces are governed by three phenomenological quantities: the coefficients of drag, lift, and moment, the latter determining the spin decay time constant. In past years, these quantities were studied mainly in wind tunnel experiments, whereby the forces on the baseball are measured directly. More recently, new tools have been developed that focus on measuring accurate baseball trajectories, from which the forces can be inferred. These tools include high-speed motion analysis, video tracking (the so-called PITCHf/x and HITf/x systems), and Doppler radar tracking via the TrackMan system. In this talk, I will discuss how these new tools work, what they are teaching us about baseball aerodynamics, and how they have the potential to revolutionize the analysis of the game itself.

The sports world provides an unlimited number of introductory physics examples. I will use a few of those examples to illustrate how an introductory physics teacher (high school or college/university) can use sports to not only teach physics but to help motivate students. Students in need of a little push may find connections to sports a way to make physics more "real world" than traditional examples.

Abstract:
|
Using video analysis software such as Tracker and inexpensive high-speed video cameras, students can do very interesting projects at the introductory level. In this presentation, I will demonstrate two projects completed by students in my introductory calculus-based physics class. (1) High-speed video analysis of a soccer ball kicked with backspin was used to measure the force and torque on the soccer ball by the foot. The force and torque were used to calculate how far off center the foot impacted the ball, i.e. the moment arm. (2) A mechanical device was used to model a hula hoop rotating around a person's arm. High-speed video analysis of a hula hoop rotating on the device showed that a point on the hoop travels in a spiral-like path. A graph of x-position vs. time for a point on the hoop was a sum of two sine curves of similar frequencies, similar to a beat pattern in acoustics.

Abstract:
|
Ethnoastronomy is the study of an indigenous people's astronomy. Through legends, winter counts, and second-hand reports, we know a great deal about astronomy on the Great Plains in the 19th century. This talk will explore how ethnoastronomers use many well-known tools of astronomy to understand phenomena, events, and beliefs of a native people. Focusing primarily on the Lakota people of the western Dakotas, examples will include eclipses, meteor showers, and the aurora borealis.

Abstract:

While attending a cultural festival at the Wind River Reservation, I brought my telescope to share with the students and their parents. During our night sky navigation, I began to hear murmured stories that were unfamiliar to me. I was intrigued; so began my journey into the rich oral/written narratives of Northern Arapaho and Shoshone cultures. This presentation will share some of the stories, resources, and websites to further enhance the astronomy experience from a native perspective.

Abstract:
|
There are many examples of non-technical physics and astronomy books that top the charts on Amazon and make it to the New York Times best-seller list. The most popular books often explore mind-bending topics like string theory, general relativity, and cosmology. While these books certainly generate excitement and fascination with physics among the general public---and future students---their prominence has the unfortunate side effect of misrepresenting the discipline as a whole. I'll discuss the sometimes unrealistic perceptions that our beginning college physics majors have about areas of research in physics and astronomy, and what we're doing to modify those perceptions without (hopefully!) diminishing students' interest in the field.

Abstract:
|
For over 25 years at Creighton University, "Dr. Zepf's Haunted Physics Lab" has been a popular outreach attraction for teaching basic principles of physics to students and the general public. Currently it is an annual Physics Club project at Creighton University during the Halloween season. In 2004 an article* about it in TPT generated wide interest. Today, applications of the haunted lab theme for teaching science are widespread both in this country and abroad. In this presentation one of the exhibits in Dr. Zepf's Haunted Physics Lab will be explained and a video of it that was made during an actual session will be shown. Watch as visitors are greeted by a seemingly bodiless "Department Head." It talks. It answers questions. It's alive!

During last summer’s Physics and Society session, there was a discussion of the benefits of the use of ground source (a.k.a “geothermal”) heatpumps. In this talk, I will briefly review how a ground source heatpump works and present some historical energy data from the use of my own unit in northern Illinois. I will also point out some reasons why these units are not the best green technology for all situations.

Abstract:
|
Inspired by concern for sustainability and environmental impact of conventional fuel usage, an introductory interdisciplinary travel course was designed. The course provides students with an understanding of the underlying physical principles of traditional and alternative methods of energy production. The Western United States is an ideal region to study practical use and research of hydroelectric, wind, nuclear, solar, ocean wave, and geothermal energy. This course, taught for the first time in January 2011, traveled by Amtrak Coast Starlight train, making stops in Washington, Oregon, and California. Students became aware of their impact on global energy by experiencing first hand the physics connection between communities and energy. This presentation will include learning objectives, energy source locations, an interdisciplinary connection to geology, and discussion of the unique opportunity for faculty to connect with students in an off-campus environment.

We live in an era when student interest in energy, sustainability, and the environment is increasing, as it becomes clear that our current production and consumption of energy negatively impacts the environment and raises a number of potentially significant challenges for the future. The primary goal of this CCLI project is to improve science education at Gustavus and other colleges across the country by taking advantage of this trend. Integrating sustainability across the science curriculum is an excellent way to educate students about this important area while teaching quantitative skills and increasing interest and enthusiasm for science. We will report on our first summer's work developing laboratory and classroom experiences and discuss plans for future work.

Abstract:
|
Few products of the industrial revolution have had as much impact on modern society as the sewing machine. The sewing machine, sometimes referred to as the "Queen of Inventions," was the first home appliance but it also brought us the "American System" of manufacturing with interchangeable parts, ready to wear clothing, the modern department store, the time payment plan, and the sweat shop. Introduced in the mid 1800s, the scientifically inclined were kept informed of each new development in the pages of "The Scientific American," and by the turn of the 20th century high school physics curriculum was being developed utilizing the sewing machine. Since most schools had little scientific apparatus and the sewing machine was rather ubiquitous, many hands-on activities were designed around the sewing machine for use in physics classrooms.

Abstract:
|
According to the AIP, in 2006 only 10% of faculty at Physics PhD-granting institutions were female. One potential contributor to this underrepresentation of women is gender bias in the hiring and promotion process. This talk will discuss a study of such gender bias in the field of psychology* and present a proposal for a similar study in physics. In the psychology study, a curriculum vita from a faculty member at the beginning or tenure phase of their career was sent to randomly selected faculty. Participants were asked to rate the content of the CV along with their decision for hiring the individual or granting tenure. The CVs were identical except that some had a traditionally male name and others had a traditionally female name. The psychology results found significant gender bias in hiring. Feedback will be invited on the design of a similar study in physics.

Abstract:
|
A new program in Energy Studies at Creighton University recently welcomed its first students. This STEM program addresses energy issues from an interdisciplinary perspective. The new bachelor of science curriculum develops applied scientists with communications skills, knowledge of public policy, law, and the human factors relevant for implementing their work. In addition to a strong emphasis on problem solving, the program seeks to instill life-long learning skills, augment team work talents, reward innovation, and enhance communication abilities. The project-based curriculum works to tailor the experience to the student. Students are asked to identify what they want from a particular learning experience and to establish expectations. Projects are formulated so that students are required to work on the areas where they need development. Projects are structured to involve active participation of the students. Students are expected periodically to reflect on their work and follow up appropriately. A BA program is also offered.

The Acoustical Society of America has recently been focusing effort on K-12 (note: the HS material works well for intro college students) outreach through a partnership with the Optical Society of America and AAPT/PTRA (Physics Teaching Resource Agents). This year the acoustical society has created a website with activities for students and materials for teachers at http://exploresound.org. The material addresses the science of sound including physics, music, our ears, animal bioacoustics, architectural acoustics, underwater acoustics, speech and medical acoustics. We've also put together a poster series with guidebooks and are working on an activity kit that will be freely available to teachers. All materials are research based and tested with students. In this presentation we will show the type and breadth of material that's available and where to find it.

Abstract:
|
Operators have a central role in the formalism of quantum mechanics. However, many students have trouble using operators in computations related to quantum measurements. Many students erroneously believe that, for operators representing observables, the linear transformation of the quantum state vector corresponds to the process of making a measurement on the system. The upper level quantum mechanics curriculum at Oregon State University takes a "spins first" approach that emphasizes quantum measurements. Within this curriculum, we have developed a variety of activities to help address this common student difficulty.

The Paradigms team at Oregon State University has developed a series of activities that emphasize quantum measurements. Some of these activities specifically target students' conceptual understanding of the role of operators in computations related to measurements. We will discuss evidence of how these activities help students develop productive conceptual understandings of operators. This evidence is gathered from classroom video of students working through the activities in small group, whole class discussions, and clinical interviews, as well as students' homework and exams.

Abstract:
|
The Physics Department at Dickinson College has re-designed its curriculum for physics majors to take advantage of recently developed single-photon experiments in quantum mechanics.* The ultimate goal is to bring students face to face with some of the fascinating and subtle features of quantum mechanics in a hands-on setting. This is mainly accomplished in a sophomore-level course titled "Introduction to Relativistic and Quantum Physics." Experiments include the behavior of a photon at a beam splitter--it "must" go one way or the other--and the behavior of a photon at a Mach-Zehnder Interferometer--it "must" go both ways. This talk will describe our curriculum changes and discuss some of the successes and difficulties we have experienced.

Abstract:
|
The classic demonstration of interference is the two-slit interferometer, so students are generally comfortable with this system and the calculations that go with it. This familiarity makes it a good system for illustrating new concepts, such as the non-local correlations seen in quantum entanglement. These can be illustrated with a modified interferometer that uses two sets of slits, one on each side of a source of momentum-entangled photons. (This actual system has not yet been realized, but a similar Mach-Zehnder interferometer has been constructed.) This system shows interference-like correlations between photons detected on opposite sides of the source, which can be very far away from each other. These correlations change with the spacing of both sets of slits, illustrating Einstein’s “spooky action at a distance.”

Abstract:

Since 2009, we have been developing and evaluating visualizations and animations for the teaching of quantum mechanics concepts [Kohnle et al., Eur J Phys, 31 6 (2010) 1441]. This new resource builds on existing education research as well as our lecturing experience, and aims to specifically target student misconceptions and areas of difficulty in quantum mechanics. Each animation includes a step-by-step exploration that explains key points in detail. Animations and instructor resources are freely available at www.st-andrews.ac.uk/~qmanim, and can be played or downloaded from this site. Animations have been used and evaluated in several quantum mechanics courses. Recent work includes extending the range of topics and levels of the animations, and a study of students' interactions with a previously unseen animation, aiming to test whether interface and content make sense, and whether the animations encourage interaction and exploration. Results of this work will be used to optimize the animations.

Abstract:
|
A number of tools are widely available to assess student understanding of key concepts in introductory physics, but less so for modern physics and quantum mechanics. The Modern Physics course at American University presents an ideal opportunity for conceptual assessment given its somewhat atypical student composition. In this study, student understanding of the photoelectric effect is probed using a variety of measures. A quantitative assessment was first performed using the Quantum Physics Conceptual Survey (QPCS)*. A series of both qualitative and quantitative exam questions were then developed and given as additional assessment measures of the photoelectric effect. In this presentation we summarize the pre-/post-gains of the assessments and correlate them with academic background and performance. The preliminary results from these assessment methods will be discussed in the larger context of how assessment measures can be maximized to enhance student understanding in a modern physics course.

Abstract:
|
The session will focus on mentoring and induction programs for new physics teachers. Students need and desire to know the latest scientific knowledge. Quantum is introduced in order to give students an understandable qualitative view of the origin of Feynman diagrams as representations of particle interactions. Elementary diagrams are combined in a simple way in order to understand the standard Model. In this presentation we examine how an alternative way of teaching can help students to design, predict interactions, and understand how the diagrams work. Using special pedagogical methods and with the help of technology, we note that most students were able to design the three interactions and to predict the formation of some particles. Without using much math, the students were allowed to develop an understanding of QED. Some misconceptions were dealt with successfully.

Abstract:
|
Traditionally the certification of physics teachers at New Mexico State University has been part of the secondary education program in the College of Education. Students select a specific science discipline (e.g., physics) as part of a general science certification, in which they declare secondary education as their undergraduate major or receive their license through a Master of Arts program as graduate students. As part of the traditional program, students take a limited number of discipline specific courses. Previously there was no option for science majors to receive a secondary science teaching license without switching majors away from their science discipline or entering the Masters program. STAND-NM, an NSF Noyce-funded program, provides a new option for science majors to pursue secondary science licensure while finishing their undergraduate degree within their science major. This talk introduces the program at NMSU and discusses difficulties in recruitment, especially with our physics majors.

Florida PROMiSE (http://www.flpromise.org/) has a mission "to improve Florida student achievement in mathematics and science through professional development for Florida's Educators and to build capacity to sustain quality implementation of the Next Generation Sunshine State Standards (NGSSS)." We participated in the design and inaugural deliveries (Summer 2009) of two institutes: Matter and Energy for K-8 teachers and Force and Motion for 6-12 teachers. With our continued participation, these institutes were revised and held again in summer 2010. This brief presentation serves to increase awareness of PROMiSE and to provide an overview of our participation, especially as it relates to "increasing the content knowledge of the participants." One outcome is our increased awareness of the "misconceptions" that K-12 students and teachers possess, and the role that a faculty member plays in reversing these misconceptions.

Abstract:
|
High school physics teachers have historically been certified at Michigan Technological University with only a general “teaching science” methods course in their education curriculum. In the spring semester of 2011 I piloted the first physics teaching methods course specifically designed to give pre-certification teachers exposure to and practice in PER-supported pedagogies. This presentation will review the curriculum and results of the new course, discuss lessons learned and take a quick look toward the future.

Abstract:
|
An Ohio Department of Education-supported project has concluded three years of funding, with a fourth pending. Student scores on the Ohio Achievement Test have climbed from the original poor level to a higher poor level in a district with about 80% of students receiving free or reduced-cost breakfast and lunch. Teachers want to continue to change. Details of the project will be presented.

Abstract:
|
We present a study involving physics teaching in Portuguese schools (seventh and eighth grades) inspired by the Core Knowledge movement (CKM), which defends the need for common curricula, well-defined teaching objectives and carefully planned classes. The project combined this approach with teacher training and weekly lab work, and required careful preparation of teaching materials (lesson plans and proposals for experimental activities), which were an outcome of the project. It was assessed with an analysis of the results of two groups; the experimental group under this instruction (CKM) and the control one, where the classes were taught the traditional Portuguese way. Data sources included analysis of the students' pre- and post-tests and interviews with the teachers involved. We found that the CKM instruction, inserted in an interactive and well-designed teaching environment, was more effective in promoting conceptual change and scientific understandings than the instruction in a traditional course.

Abstract:
|
How do universities and colleges attract undergraduate physics majors into becoming high school physics teachers? It has been my task at UNC-Chapel Hill to talk to the physics majors and present the reasons why teaching high school physics can lead to a satisfying career as well as making a major social contribution to the planet. Few careers offer the enormous influence and satisfaction as does teaching high school physics. Many people look back on their life and wonder what they have given to the planet. An effective physics teacher can influence the manner in which a person thinks and lives their life. Now is the time to create a new breed of extraordinary high school physics teachers.

Abstract:
|
The results of physics education research and the availability of microcomputer-based tools have led to the development of the activity-based Physics Suite.1 Most of the Suite materials are designed for hands-on learning, for example student-oriented laboratory curricula such as RealTime Physics. One reason for the success of these materials is that they encourage students to take an active part in their learning. This interactive session will demonstrate “through active audience participation” Suite materials designed to promote active learning in lecture and Interactive Lecture Demonstrations (ILDs).2 The demonstrations will be drawn from second semester topics.

Camcorders can help students to observe simple circular motions of a bicycle wheel and a simple pendulum. Video analysis will be used to study the circular motions, and allow students to build up concepts of vectors involved in the kinematics of circular motions, such as angular velocity and angular momentum. How to build the mathematical formula for students based on their observation will be discussed.

Abstract:
|
On average, contingent (part-time) faculty teach nearly half of the course s at community colleges. The effect of this on student retention, success, and graduation rates is either assumed to be negative or remains unknown to most faculty and college officials. In this presentation, I will review the latest research on the effects that extensive use of part-time faculty has on student success, retention, transfer rates, and graduation rates.

Abstract:
|
This talk will review significant public policy issues regarding the over-use of part-time positions generally and in physics in particular in higher education. Along with the negative effects on individual faculty and on departments, these include a number of negative impacts on students: on retention and degree completion, on efforts to prepare students for success in meeting STEM education goals, and on initiatives to move college physics pedagogy in a more student-focused direction. Finally, the talk will review and explore legislative approaches to this growing problem.

The widespread use of part-time positions has serious structural implications for faculty, departments, and the overall health of higher education. The discussion will cover several broad issues including the effects on faculty infrastructure, equity, academic democracy, and academic freedom, as well as model approaches for correcting dependence on contingent faculty. The pervasiveness of part-time positions provides physics faculty members with allies in addressing this issue as well as promising approaches based on the broad and diverse faculty experience.

Abstract:
|
How can we provide an authentic research experience to students who want to find out what science is REALLY about? We couple DS9 imaging software, a user friendly, fun-to-explore environment with a "virtual observatory" that allows analysis to be done remotely on UNIX-based computers, regardless of the platform employed by the user. All of NASA's archived satellite observations can be accessed by any interested student. Furthermore, by adapting VNC (Virtual Network Computer) software, we can enhance this flexibility enormously and allow instructors to view, comment on, and debug any analysis task in real-time, from anywhere in the world, and across all computing platforms. This makes these programs especially useful in distance learning environments.

Abstract:
|
For over 10 years now we have taught an observational astronomy class at an advanced undergraduate level. This class teaches the methods of data acquisition, data processing, data analysis, and writing for publication, using optical data obtained on a CCD camera. The class is designed around teaching students the skills used for professional astronomical research, including the use of the IRAF reduction package developed at NOAO. The question then arises, can we train a younger group of students to perform full astronomical reductions? Over the last year we have begun development of a workshop for local high school teachers, or teachers from small colleges, to give them the tools to fully reduce astronomical data. We also had a local high school student come to us as an intern. He became our first test subject. We will report on our experiences.

Abstract:

We have demonstrated that research images from the BYU West Mountain Observatory can often be combined to produce images that are suitable for classroom use. This process can usually be completed with little or no effort being made to secure additional image data after the completion of a research project. Results will be shown for images processed from frames obtained for science investigations and compared with images where the data were obtained specifically to produce an instructional image. We also present two amimations where the data frames are from nightly monitoring projects. Images can be previewed at the website in the abstract footnote.

Abstract:

From Doctor Octopus from Spiderman to Maggie Walsh of Buffy the Vampire Slayer season 4, scientists are often portrayed as evil geniuses intent on using their high IQs to take over the world. Does this affect how the public views scientists? Science in general and physics specifically is so often thought of as "scary." Misconceptions about talking robots and world eating black holes can turn people against physics and the "evil genius" scientists that will destroy the world, either by accident or on purpose.

Why leave it up to the"experts" (i.e., the media) to portray physics accurately and positively? Speak for yourself, without the need for a translator who may "or may not" get it right. As a scientist, you can talk about what your work means and why it's important with an authority that a science writer doesn't bring to the table. While we can't all be Brian Greene, you can have control over how your work, and physics in general, is presented to the public. In this talk, I'll share some best practices of science communication, gleaned during my time as a science reporter at NPR and elsewhere. These simple tips can take a lifetime to master, but can help you get your message across, to the public, the media, and even Aunt Mabel.

Abstract:

It could be argued that physics and physicists have not had such popular exemplars as Sheldon and Leonard (the main characters on CBS' Big Bang Theory) since the death of Albert Einstein. Dr. David Salzberg consults on the physics shown on white boards in the show so that material is trustworthy. But how "true" is the representation of physics and physicists that Sheldon and Leonard present to the general public on television every week? How about the female scientists who show up in recurring (though generally not starring) roles? Does it really matter if a TV comedy re-enforces stereotypes about science and scientists? What effect could this show have on students? Interest in learning physics in high school or college? As a physics educator I am concerned that this show and others like it will exacerbate the trend of undergraduates moving away from the physics major.

Abstract:

Most of us have watched the "Big Bang Theory" on television and thought at times, this reminds me of Dr. X or Dr. Y. Other scenes make us think that isn't true of physicists we know….or is it? Are these depictions characteristic of us? Greater discussion of physics and science from my students seems to come from "Mythbusters" and some other science shows on television now hosted by real physicists. How do TV shows portray scientists? This will examine how various groups (physics majors, nonmajors, etc.) perceive physics/science (i.e. the endeavor) based upon watching physicists/scientists on television. How do they perceive those that do science? Is this perception negative so that it might persuade a high school student to change his mind about becoming a physicist? Is this perception positive for male students? For female students?

Abstract:
|
Physics Resources and Instructional Strategies for Motivation Students (PRISMS) is a high school physics curriculum that utilizes a learning cycle pedagogy. PRISMS originated in 1982 as a collection of 130 high interest activities related to real-life student experiences. PRISMS was revised and enhanced with funding from the National Science Foundation and made available as PRISMS PLUS. PRISMS PLUS is based on physics education research and the recommendations of national science education initiatives. Students are guided through high-interest activities that engage them in exploring patterns and relationships; formulating concepts based on evidence; and applying these concepts to new phenomena, using the concepts to predict the behavior of physical phenomena. PRISMS PLUS includes more than 40 complete learning cycles with conceptual support materials to help students develop conceptual understanding of the basics physics ideas introduced. PRISMS provides the pedagogy for many of the UNI Physics preparation and professional development programs for science teachers.

Abstract:
|
We often spend the first week of classes teaching our students how science works and then switch to our traditional delivery mode telling them what the laws of physics are and how to use them to solve back-of-the-chapter problems. Is it possible for our students to learn physics concepts and laws by actually practicing science? What does it mean to practice science in a high school classroom? In this talk I will describe two curricula, "Investigative Science Learning Environment" (ISLE) and Physics Union Mathematics (PUM), that engage your students in the processes mirroring scientific practice when learning physics. These curricula help them experience physics first hand as their own creation. They engage the students in data collection and analysis, help them learn how to devise their own explanations, how to test them with new experiments, and how to make meaningful connections to mathematics.

The latest information released by College Board in regard to the new AP Physics B courses--Physics 1 and Physics 2 will be presented, including an overview of the curriculum framework along with the division of content between Physics 1 and Physics 2. Currently, Physics B is supposed to follow a preparatory course. Now, the material is divided up and deepened to make each year a stand-alone, rigorous, conceptual and problem-solving course. These courses can be placed flexibly into a school's curriculum; examples, alignment of the courses with college courses and possible ramifications for college credit will be discussed.

Abstract:

The conceptual level for the newly designed course will be significantly deeper, thereby allowing teachers more time for inquiry-based, student-centered learning. Suggested approaches to the incorporation of elements of the redesigned courses into current AP Physics courses will be offered as teachers plan during the interim between now and first year of implementation of the new curriculum. New teachers will discover an approach to physics teaching that merges conceptual development with scientific practice. Experienced teachers will see how their current practices merge with the goals of Physics 1 and Physics 2. Participants will gain insight into what impact these changes may have on their current teaching practices. Participants will be given examples of how these new courses can be placed flexibly into a school's curriculum, and the teacher support materials that will accompany both courses will also be discussed.

Abstract:
|
As part of a larger study to understand how instructors make teaching decisions, we investigated how graduate teaching assistants (TA's) perceive features of written problem solutions. TA's are an important population to understand; they often provide significant instruction and they also represent the pool of future physics faculty. This talk will focus on the methodology used to study TA's enrolled in a training course. Data were collected via a series of tasks related to concrete instructional artifacts (solutions to the same physics problem that vary in their representation of expert problem solving as well as in their instructional approach). Important aspects of the design were a) using artifacts from a previous study of faculty to allow for comparison of results, b) developing a written questionnaire that requires respondents to explicitly connect problem features with preferences and reasons, and c) documenting respondent ideas both pre- and post-discussion within their training course.

Twenty-four first-year graduate TA's enrolled in a training course were provided with different instructor solutions for the same physics problem and asked to discuss their preferences for prominent solution features. Preliminary findings reveal that providing a schematic visualization of the problem, listing knowns/unknowns, and explaining reasoning in explicit words were the most valued features. Preferences for different features were sometimes in conflict with each other. For example, while the TA's valued solutions where reasoning was explicitly explained, they also valued concise solution. We'll present the reasons behind these preferences and discuss the implications for the professional development of physics TA's.

Abstract:

We have analyzed reflections from our chemistry, mathematics, and physics undergraduate learning assistants (LAs) seminar to examine their development of reflective teaching practices. One goal of Florida International University's (FIU) LA seminar is to help our participants develop as reflective practitioners. We endeavor to reach this goal by means of classroom activities, classroom discussion, and reflective homework assignments. Weekly reflective papers on course readings and teaching experiences are assigned to help our students reach higher levels of reflection. To assess our Las' level of reflection, we analyzed reflections using Hatton and Smith's (1995) [1] "criteria for the recognition of evidence for different types of reflective writing." The three discipline-based LA programs at FIU utilizing the LA seminar are structurally different and include different kinds of teaching experiences. Thus, we have also investigated whether or not participation in the various programs may result in different levels of reflection for the Las.

Abstract:

We report on the results of a recent effort to modify graduate Teaching Assistant (TA) preparation for the Tutorials in Introductory Physics by focusing instructor attention on potential student difficulties rather than simply the mastery of content. We track shifts in instructor awareness of student difficulties with Tutorials as a result of a simple intervention during TA preparation sessions. We share findings from this semester-long effort, and conclude by discussing broader implications for teacher preparation in both traditional and transformed environments.

Abstract:
|
The Colorado Learning Assistant (LA) Program serves as a content-specific supplement to standard teacher preparation programs. In addition to transforming undergraduate STEM courses, it recruits and prepares math and science majors for teaching careers by involving university STEM faculty. The research reported here compares the teaching practices of in-service teachers who had the LA "treatment" as undergraduates to colleagues who did not participate in the LA program as undergraduates but were certified through the same program. We report on teachers' views of assessments, their views of learning, and differences in their teaching practices. This analysis is based on interviews with approximately 30 teachers and observations of their classrooms throughout their induction years of teaching. This work considers how the LA program may help improve current teacher preparation models.

Abstract:
|
The Scoop notebook [1] is an instructional artifact package developed to assess teachers' use of reform classroom practices. It is one of the tools used by University of Colorado's LA-Test research group to characterize differences in the classroom practices between former Learning Assistants (Las) teaching at the secondary level, and their colleagues. Analysis of these artifacts indicate significant differences between LA and non-LA groups. Other data sources corroborate these findings [2]. We will discuss the implications of this study and make inferences about the role of the LA experience in teacher preparation. We will also describe the method of using artifact packages to study classroom practice, discussing the pros and cons of this type of data.

Abstract:
|
We present a case study of two introductory undergraduate physics students' increasing participation in the physics learning community at Florida International University (FIU). An implicit goal in the reforms implemented by the Physics Education Research Group at FIU has been the establishment of multiple opportunities for entry into and participation in a community of physics learners. These opportunities include classes using research-based curricula (Modeling Instruction and Investigative Science Learning Environment), a Learning Assistant program, and a growing cohort of physics majors. Using interviews conducted across a year of introductory physics, we explore the trajectories of two students who have successfully increased their participation in a physics learning community.

Abstract:
|
The nature of energy is not typically an explicit topic of physics instruction. Nonetheless, participants in physics courses that involve energy are constantly saying what kind of thing they think energy is, both verbally and nonverbally. The premise of an embodied-cognition theoretical perspective is that we understand the kinds of things that may exist in the world (ontology) in terms of sensorimotor experiences such as object permanence and movement [1]. We offer examples of intuitive ontologies for energy that we have observed in classroom contexts, including energy as a quasi-material substance; as a means of activation; as a fuel; and as an ineffable quantity which is not subject to further analysis. In the classroom, multiple and overlapping metaphors for energy complement one another in complex representations of physical phenomena. [2]

Abstract:
|
The concept of "productive disciplinary engagement" [1] (PDE) provides a layered method for describing experiences in which learners are interacting with one another. The four principles of PDE align with much of the Physics Education Research community's effort in instructional design: 1) Problematizing Content, 2) Giving Students Authority, 3) Holding Students Accountable to Others and Disciplinary Norms, and 4) Providing Relevant Resources. Authentic experiences of this kind are not common in most classrooms and significant challenges arise when attempting to create them. We present examples of PDE from a summer Professional Development course on energy at Seattle Pacific University and consider both the observational criteria by which PDE is identified and the features of the instruction that contributed to making it possible.

Abstract:
|
In group settings, we sometimes see learners commit to arguments that, although seemingly contradictory, are both correct and appropriate. Groups may have difficulties reconciling these competing commitments. In a professional development course at SPU, secondary teachers are discussing the energy flow in a refrigerator to find out how refrigerators work. While one teacher shows commitment to the idea that refrigerators move heat from a relatively cold compartment to a hotter environment, two others appear committed to the second law of thermodynamics which states that heat flows from hot to cold. Video records of the discussion show that the teachers recognize the disparity of their commitments but do not spontaneously reconcile the contradiction. Our analysis shows why all group members are right to believe in their respective commitments, points out difficulties they have reconciling the contradicting commitments, and explores possible causes for these difficulties.

Abstract:
|
National and state standards often list forms of energy that students should know, including gravitational, kinetic, potential, etc. Form can be a useful shorthand for describing the state of the system, or it can be a meaningless label to be memorized. Most physics instruction does not emphasize a deep understanding of the physical meaning of form. Are there ways that our instruction could more effectively help students gain an understanding of form? One way to develop and test understanding of forms of energy is to ask the question, "What must be considered when deciding whether a new form is legitimate?" We present case studies of students struggling with the legitimacy of forms of energy not listed in the standards, some of which they deem to be legitimate and some of which they do not. Finally, we suggest instructional methods to take advantage of this struggle.

Abstract:
|
When teaching about energy in physics class, an important learning goal for students is an understanding of conservation of energy. Outside of physics class, the word "conservation" is often used with an entirely different meaning: In the real world, we care about "conserving" a finite and expendable resource. This resource is often referred to as "energy," but in the more precise language of physics we would call it "useful energy" or "value" in energy. We present results from a collaboration in which SPU visual communication majors, after extensive discussions with members of the physics department, produced posters to depict various energy concepts and to communicate their understanding. Many of these posters explicitly highlight the distinction between "energy" and "value," Illustrating how nonscientists struggle with this issue. We discuss how this struggle may play out for students in physics classes, and suggest a method for redirecting students' useful intuitions about value.

Abstract:

In order for students to relate quantum and classical mechanics they must have a sufficiently strong foundation of some basic concepts in classical physics. We have found that students in introductory courses who are learning quantum mechanics sometimes struggle with these classical concepts in ways that can inhibit their ability to connect these two regimes. Examples of our findings in the context of potential energy diagrams, as well as preliminary attempts to address student difficulties, will be presented.

Abstract:
|
A basic assumption of kinetic-molecular theory is that the pressure of a gas is generated by collisions of gas particles with the walls of the container. This assumption is often used to derive an expression that relates the pressure of a gas to the kinetic energy of the gas particles and ultimately connects the microscopic model for pressure to the ideal gas law. In a series of questions that were developed to elicit microscopic descriptions of pressure, student and teacher explanations revealed a variety of macroscopic and microscopic descriptions of pressure that had no obvious connection to collisions of gas particles with the container walls. Examples will be presented, together with a brief discussion of possible implications for instruction in physics and chemistry courses.

Abstract:
|
Students' responses to questions about wave propagation along a taut spring indicate that many believe the effort exerted by the hand making a wavepulse affects the speed with which it moves.[1] We have previously suggested that these responses may depend on how the students imagine the physical scenario--is the hand creating a wavepulse on an already taut spring, or is the spring first pulled taut and then the wavepulse is created?[2] In the latter situation, we expect students to be more inclined to correctly think of the tension on the spring affecting the wave speed. We created two interview tasks to investigate our prediction. Evidence shows that students who pull the spring taut before creating a wavepulse do not answer questions about wave speed by discussing "the force imparted to the wave."

Abstract:
|
More than 12,000 articles have been published on the physics of percolation, yet only a handful have attempted to teach the concept to undergraduate students. However, with increases in computing power and widely available software packages, getting started on the study of percolation is a much simpler task today than it was 30 years ago. In this presentation, we show how undergraduate science and engineering students can use a standard desktop computer running Mathematica to perform sophisticated investigations of two-dimensional lattices. In a special topics research course, second-year students learned how to simulate percolation in various lattice geometries, calculate cluster statistics, and extract critical exponents from the simulation data. These students made fundamental connections between the mathematics and physics of percolating systems and reached an understanding of a fundamental physical process that unfortunately, is not often part of a typical undergraduate curriculum.

Abstract:
|
Real-time frequency analyzers (RTFAs) are available as free online downloads, and they are incorporated even in entry-level music production programs such as Apple's GarageBand. Outputting the sound of a drawbar organ though an RTFA clearly shows the analyzer's function. I will present some ways in which this software can be used to display spectral subtleties of sounds that single instantaneous Fourier transforms cannot reveal. When a string is plucked, harmonics initially decay at different rates. Real-time spectral analysis of speech exposes difficulties in representing vowel and consonant sounds as Fourier series. An RTFA provides a useful tool for showing how "resonance box beating" extends to the beating of harmonic waves. Additionally, an RTFA explains why the sound of harmonic waves beating resembles sound processed by a musical phase shifter.
