Abstract

fetched live from OpenAlex

Quand plusieurs études par comparaison de groupes (intervention et témoin) portent sur une même intervention en milieu scolaire, la synthèse de leurs résultats permet d’évaluer l’effet de cette intervention et de répondre aux attentes des praticiens, mais aussi d’orienter les recherches futures. C’est dans ce but que sont réalisées des synthèses quantitatives ou encore des méta-analyses. Pour chacune des études sélectionnées, une taille d’effet est calculée, qui est le g de Hedges (différence standardisée des moyennes des deux groupes) quand la variable à expliquer est un score post-test. La taille d’effet globale est alors estimée en suivant dans la plupart des cas le modèle des effets aléatoires. Enfin, pour conclure quant à l’intérêt de l’intervention, les tailles d’effet sont traduites en nombre de mois de progrès. Un exemple numérique est proposé pour faciliter la compréhension des modèles analytiques mis en oeuvre dans une méta-analyse pour les cas les plus simples.

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.
