UNCG has an innovative Learning Assistant (LA) program, in which upper-class undergraduate physics majors teach laboratory sections of the introductory calculus-based physics sequence. The lecture section's professor provides supervision and determines the overall learning objectives and structure of the labs, but the team of LAs develop the detailed lesson plans, write up all handouts and quizzes, conduct the lab sessions, and evaluate student work. This gives the LAs a genuine voice in planning and teaching, and increases the authenticity of the teaching experience. In order to investigate the impact of this teaching experience upon physics majors, we interviewed five current and former LAs. We analyzed the interview transcripts via emergent thematic analysis to identify the most prevalent impacts, and then viewed the results through the lens of professional identity development. We claim that the LA experience helps grow three aspects of physics majors' professional identity: their sense of themselves as a physics teacher, as a physics student, and as a member of a community of practice.

Abstract:We investigated student reactions to two computational physics courses incorporating several videogame-like aspects. These included use of gaming terminology such as "levels," "weapons," and "bosses"; a game-style point system linked to course grades; a self-paced schedule with no deadlines; a mastery design in which only entirely correct attempts earn credit, but students can retry until they succeed; immediate feedback via self-test code; an assignment progression from "minions" (small, focused tasks) to "level bosses" (integrative tasks); and believable, authentic assignment scenarios. Through semi-structured interviews and course evaluations, we found that a majority of students considered the courses effective and the game-like aspects beneficial. In particular, many claimed that the point system increased their motivation; the self-paced nature caused them to reflect on their self-discipline; the possibility and necessity of repeating assignments until perfect aided learning; and the authentic tasks helped them envision using course skills in their professional futures.
