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:

DynaMo is a program for developing, editing, and delivering simulations of a wide range of physical systems typically encountered in introductory physics and classical mechanics classes. I will be demonstrating a variety of newly created simulations and discussing various ways they can be delivered to students.

Abstract:
|
Geometer's Sketchpad by Key Curriculum Press was created as a tool for teachers and students to model geometric situations. We have adapted it to create dynamic models of physics phenomena. We will show how to create an illustration and give examples of teacher and student sketches. We suggest the student is learning physics by building the sketch and then by using it as a tool to explore and analyze physics concepts.
