Abstract
The theory of teachers'professional knowledge has been reconstructed through an expansion of the MK to MPCK among academics.MPCK,originally developed on the theory of knowledge of pedagogy,refers to an exclusive domain of knowledge on the part of teachers,incorporating knowledge of mathematics,of pedagogy,and of learning.It is an important indicator of teachers'professional development,reflecting teachers'proficiency in both mathematicsand mathematics pedagogy.Drawing on theories related to MPCK,the present paper argues that an active enhancement of technical knowledge on the part of math teachers is a prerequisite for the success of math teachers'professional development,of which,apractice-oriented teacher education serves as the cornerstone.

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
