          At Florida International University we have implemented a learning as-
        
        
          sistant (LA) program based on the Colorado Learning Assistant Model
        
        
          (Otero, Pollock, Finkelstein, 2010), designed to help prospective and
        
        
          preservice science and mathematics teachers to develop pedagogical con-
        
        
          tent knowledge, develop as reflective practitioners, and gain experience in
        
        
          teaching early in their academic careers. As a part of the program, LAs are
        
        
          helped to develop reflective practice. We believe that reflective practice is a
        
        
          kind of deliberate practice that helps novice teachers to hone their teaching
        
        
          skills as they strive toward expertise in teaching. To better understand the
        
        
          needs of our LAs in this development, we interviewed a number of them to
        
        
          better understand their perspectives in regard to teaching, reflection, and
        
        
          expertise. Analysis of these interviews revealed LAs’ perspectives on the
        
        
          value and purpose of the LA program. LA viewpoints in this regard will be
        
        
          presented.

          Help TAs Adopt Researched Pedagogy

          Teaching assistants (TAs) are both the present and the future of sustainable
        
        
          quality physics education. However, prior research has raised concerns
        
        
          with limited TA training and/or training that attempts to “fix” TAs without
        
        
          giving sufficient respect to their prior beliefs and teaching experiences.
        
        
          In our study of four first-year physics courses, we applied a community-
        
        
          centered model to TA professional development. During weekly course-
        
        
          specific tutorial preparation meetings, we encouraged TAs to experiment
        
        
          with research-based pedagogy and share their successes and failures. The
        
        
          facilitator of these weekly preparation sessions attended some tutori-
        
        
          als to provide feedback and promote teaching peer review. We observed
        
        
          interconnected influences from perceptions of professors’ commitment to
        
        
          teaching, TAs’ and peers’ teaching experiences, and department teaching
        
        
          culture on fostering or discouraging TA buy-in to researched pedagogy.
        
        
          Respectful TA professional development that builds physics teaching
        
        
          communities shows promise for increasing adoption of active learning
        
        
          pedagogy in physics education.

          Teaching assistants play a very important role in teaching university phys-

          classes, tutorials, and even some lectures. Research seldom has focused on
        
        
          how to improve TA’s role. As a teaching assistant myself, I have encoun-

          concepts. My investigation is on how to best assist teacher and students
        
        
          and what kind of bridge should the TA build between teacher and students.

          Using Force Concept Inventory*

          The Force Concept Inventory (FCI) has been widely used to assess student
        
        
          understanding of introductory mechanics concepts by a variety of educa-
        
        
          tors and physics education researchers. One reason for this extensive use
        
        
          is that many of the items on the FCI have strong distractor choices that
        
        
          correspond to students’ alternate conceptions in mechanics. Instruction is
        
        
          unlikely to be effective if instructors do not know the common alternate
        
        
          conceptions of introductory physics students and explicitly take into
        
        
          account students’ initial knowledge state in their instructional design.
        
        
          We used the FCI to evaluate the pedagogical content knowledge of both
        
        
          instructors and Teaching Assistants (TAs) of varying teaching experience.
        
        
          For each item on the FCI, the instructors and TAs were asked to identify
        
        
          which incorrect answer choice they believed would be most commonly
        
        
          selected by introductory physics students. We used the FCI pretest and
        
        
          post-test data from a large population (~900) of introductory physics
        
        
          students to assess the pedagogical content knowledge of these educators.
        
        
          We will present these results.

          Physics Teaching Assistants (TAs) play an important role in supporting
        
        
          transformed learning environments, often by engaging students in ways
        
        
          that may differ from their own experience as learners. Through their par-
        
        
          ticipation in these environments, TAs are developing beliefs about not only
        
        
          what it means to teach, but also how to put it into practice. In this talk we
        
        
          present a validated and refined framework for connecting TAs’ stated be-
        
        
          liefs about teaching to their enacted instructional practices, and apply this
        
        
          framework to sample interview and classroom video data. We conclude
        
        
          with a discussion of how this framework may be used to examine variation
        
        
          in beliefs and practices, track the development of beliefs over time, and
        
        
          inform TA preparation.

          The George Washington University, a major research university, is also
        
        
          strongly committed to outstanding teaching. An important part of the
        
        
          teaching commitment refers to training doctoral students to become future
        
        
          faculty. This training seeks to expose these students to active learning tech-
        
        
          niques. We will present how the university and the Department of Physics
        
        
          initiatives led to an approach to train the students, including: a) a manda-
        
        
          tory online graduate teaching assistant certification course, b) a manda-
        
        
          tory in-class training program within the department, and c) an optional
        
        
          in-class future faculty training program. We will discuss our framework
        
        
          and our multi-dimensional assessment that features graded papers, graded
        
        
          classroom observations, interviews with outstanding teachers, surveys,
        
        
          and instructors’ and students’ evaluations. This project is sponsored in part
