Abstract

fetched live from OpenAlex

Cette recherche, réalisée en milieu scolaire québécois, concerne l’enseignement et l’apprentissage de la géométrie à l’entrée au secondaire. Ce contexte est caractérisé par une géométrie non clairement définie d’un point de vue épistémologique, tant dans le programme d’études du premier cycle que dans les manuels scolaires. Ainsi, nous avons cherché à voir d’une part, l’activité géométrique souhaitée et actualisée par des enseignants incluant les problèmes proposés et, d’autre part, les conceptions d’élèves développées par ces problèmes. À partir de données recueillies auprès de quatre classes, nous avons déterminé cette activité géométrique et répertorié six types de problèmes dont quatre sont dominants ainsi que des conceptions d’élèves. L’activité géométrique en classe a donné lieu à des moments d’hésitation épistémologique, lesquels ne sont pas sans effet dans le développement des conceptions des élèves.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
