Abstract
Research-based instructional strategies have been shown to dramatically improve student learning, but widespread adoption of these pedagogies remains limited. Post-secondary teaching assistants (TAs), with their current positions in course delivery and future roles as academic leaders, are an essential target group for teacher training. However, the literature suggests that successful TA professional development must address not only pedagogical practices but also the cultivation of physics educator identity. The primary goal of this study is to build a framework for TA professional development that strengthens the TA's identity as a physics educator. We base this framework on Etienne Wenger's model for communities of practice and Côté and Levine's personality and social structure identity perspective. We explore this framework in the context of a 12-week, low-cost, TA-led and TA-centered professional development intervention. Our qualitative and quantitative data suggest that this efficient community-based intervention strengthened TAs' identification as physics educators.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
