La résolution de problèmes, un lieu privilégié pour une articulation fructueuse entre arithmétique et algèbre
Bibliographic record
Abstract
Cet article traite des difficultés qu'éprouvent plusieurs futurs enseignants à articuler les domaines de l'arithmétique et de l'algèbre dans un contexte de résolution de problèmes. L'analyse d'entrevues réalisées auprès d'apprentis-enseignants qui mettent spontanément en place une dialectique entre ces domaines de connaissances illustre les différents statuts et rôles que peuvent prendre tour à tour l'arithmétique et l'algèbre dans le processus de résolution de problèmes. Les résultats font ressortir le rapport aux savoirs arithmétique et algébrique qu'il serait souhaitable de retrouver chez les futurs enseignants et les aspects qu'il serait opportun de travailler non seulement avec eux mais aussi avec les élèves.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
