Abstract

fetched live from OpenAlex

Cet article présente un exemple d'utilisation de la méthodologie des situations didactiques pour identifier un obstacle didactique dans un problème d'enseignement des mathématiques: il s'agit de l'enseignement du concept d'angle de secteur aux élèves entre 10 et 13 ans. En s'appuyant sur l'analyse d'erreurs faites par les élèves, les auteurs reprennent à leur compte l'identification d'une conception erronée de l'angle déjà formulée par Balacheff. Ils proposent une explication à la production de cette conception par l'enseignement usuel et présentent de manière détaillée un processus d'enseignement qu'ils ont élaboré et qui permet aux élèves de surmonter cet obstacle.

Full frame distilled prediction

Teacher imitation

Not 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.
