Utilización De La Tecnología En El Tránsito Entre La Aritmética Y El Álgebra: Construcción Socio-cultural De Expresiones Algebraicas Para El Cálculo De Números Triangulares
Bibliographic record
Abstract
En este documento estamos interesados en la problemática de la transición entre la aritmética y el álgebra. Varios estudios aportan contribuciones sobre el pensamiento algebraico para caracterizar este pasaje. En este trabajo queremos estudiar lo que hemos llamado el pensamiento aritmético-algebraico como previo al pensamiento algebraico y una entrada « natural » al álgebra. Para hacer emerger el pensamiento aritmético-algebraico en los alumnos, hemos construido una actividad de generalización de "patterns" sobre los números triangulares. Esta actividad permite el surgimiento de representaciones funcionales a través la utilización de la tecnología y de la visualización matemática favoreciendo una actitud de control de parte de los alumnos. Presentaremos algunos de los resultados de las experimentaciones en México y en Quebec. La metodología ACODESA que utilizamos favorece como lo veremos una construcción socio-cultural, en nuestro caso de fórmulas.

How this classification was reachedexpand
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.
