          We focus on the design and study of a meta-cognitve approach to the pro-
        
        
          fessional development (PD) of high school physics teachers. We designed
        
        
          and study a courses that is a part of a two-year M.Ed. program designed
        
        
          for experienced high school science teachers. The teachers were asked to
        
        
          develop teaching units in physics and were given the opportunity to teach
        
        
          and apply their units to children participating in an enrichment program
        
        
          in the college. The goals of our study were to characterize the design prin-
        
        
          ciples of the teaching units and to examine the changes in the design that
        
        
          followed the interactions between the participants in order to understand
        
        
          the teachers’ meta-cognitive knowledge about designing teaching units in
        
        
          physics. The data included: interviews with the teachers; reflections of the
        
        
          researchers; the teachers’ teaching units and activities; and observations of
        
        
          the teachers’ physics lessons.

          The Fostering Learning Improvements in Physics (FLIP) project has
        
        
          examined in detail the state of Physics Education Research in the UK,
        
        
          how PER has impacted on the teaching and learning of physics, and how
        
        
          physics teaching develops in practice. The project was commissioned by
        
        
          the Institute of Physics (the UK’s professional body in physics) and by the
        
        
          Economic and Social Research Council to determine how best to facilitate
        
        
          the growth of PER in the UK. FLIP has provided a detailed and compre-
        
        
          hensive picture of UK PER and also of the key challenges facing effective
        
        
          teaching and learning of physics. We will present some of the key findings,
        
        
          contrasting them with the situation in the US and elsewhere in the world,
        
        
          and discuss the wider implications.

          Numerous studies indicate that spatial reasoning can play a role in STEM
        
        
          field success. Introductory university physics frequently requires students
        
        
          to construct integrals, a skill that may be influenced by spatial reasoning
        
        
          proficiency. We administered a straightforward physics problem requiring
        
        
          the construction of an integral to students enrolled in calculus-based intro-
        
        
          ductory physics, and additionally measured their spatial reasoning ability
        
        
          using the Santa Barbara Solids Test. We found that the spatial reasoning
        
        
          score correlates moderately with overall performance on the integration
        
        
          task, as well as with various components of integral setup, such as correctly
        
        
          identifying cross-sectional area. Furthermore, we found that students
        
        
          who demonstrated a physical understanding of the integrand, via a simple
        
        
          multiple-choice question, were significantly more successful in construct-
        
        
          ing the integral, independent of spatial reasoning ability.These results
        
        
          suggest that, separately, both spatial reasoning and physical understanding
        
        
          of the integrand are important for constructing integrals in physics.

          This study aims to determine critical factors that explain differences in FCI
        
        
          gains among sections of algebra-based and calculus-based classes. In this
        
        
          study, FCI pre-test scores are found to be only moderately correlated with
        
        
          FCI post-scores and normalized gains, and Lawson CTSR scores are only
        
        
          weakly correlated. We conclude that measures of scientific reasoning ability
        
        
          and the level of prior knowledge of physics are not the most important fac-
        
        
          tors in explaining course section differences. We report also on the devel-
        
        
          opment of a rubric for quantifying the degree of FCI content coverage. This
        
        
          work contributes to the PER community’s efforts to identify a sufficiently
        
        
          complete set of factors impacting FCI gains and to determine the rela-
        
        
          tive importance of the factors. Work in this area could guide curriculum
        
        
          reform to reduce students’ misconceptions about Newtonian Thinking and
        
        
          allow them to learn more physics beyond the topics addressed by FCI.

          Demonstrations are a vital part of the introductory physics lectures for sci-
        
        
          ence majors at the University of Bern, Switzerland. Performing the demos
        
        
          using a mix of modern techniques such as video projections, alterna-
        
        
          tive lighting, and LabVIEW virtual instrumentation helps to emphasize
        
        
          the physical content. This allows the students to focus on the concepts
        
        
          involved. Some examples of how classic demonstration experiments are

          Physics teaching to a first-time student should be an exciting adventure.
        
        
          Using the idea of the “Same Physics Different Ways” I will outline how a
        
        
          rural high school grew its physics programs from one class to seven classes
        
        
          of physics. Highlighted will be physics activities and projects that my stu-
        
        
          dents still ask me about when I run into them 30 years later. The big ideas
        
        
          of the class from projects to problems all will be shared.

          The video format has many advantages over other forms of information
        
        
          transfer. Videos lend themselves to group work and generate more discus-
        
        
          sion than written problems because the real world is more compelling,
        
        
          opened-ended, and messy than the sanitized versions of reality that physics
        
        
          students often deal with. For this reason (as well as many others) my col-
        
        
          laborators and I have been working to create a library of short, high-quality
        
        
          videos of real situations that allow students to directly analyze and measure
        
        
          phenomena. In this talk I will discuss the advantages of using Direct Mea-
        
        
          surement Videos and will share highlights from our video library.

          We have seen for many years the iPhone being a useful tool in the Phys-
        
        
          ics Classroom. But now, there is a new feature that is ready to make big
        
        
          changes. The slow motion feature on the iPhone 5s provides a convenient
        
        
          enhancement for many physics demonstrations, both old and new, and
        
        
          in some cases it enables experiments that were previously impossible! In
        
        
          this talk I highlight 10 of these and provide tips for successful slow motion
        
        
          videos.
