Abstract
The purpose of this study was to develop pre-service secondary teachers' technological pedagogical contentknowledge (TPACK) for teaching mathematics with The Geometer’s Sketchpad (GSP) through Lesson Study(LS). Specifically, a single-group pretest-posttest design was employed to examine whether there was asignificant difference in the pre-service secondary teachers' TPACK for teaching mathematics with GSP afterengaging in LS which was incorporated into the mathematics teaching methods course during the first semesterof the 2011/2012 academic session in a Malaysian public university. Forty-six pre-service secondary teacherswho enrolled in the course completed both the pretest and posttest questionnaires on teachers' TPACK forteaching mathematics with GSP. The results of the paired-samples t-test indicated that there was a significantdifference in the pre-service secondary teachers' TPACK for teaching mathematics with GSP for all thesubscales after engaging in LS.

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
