Pérégrinations et badaudage : avantages et limites d’un environnement de réseautage social éducatif
Bibliographic record
Abstract
Dans le cadre de notre recherche sur les problèmes d'abandon en formation à distance (FAD), nous avons introduit un environnement de réseautage social éducatif (ELGG) dans trois établissements postsecondaires canadiens, selon une méthodologie de type « design-based experiment ».Quarante pour cent des étudiants se connectent à l'environnement, le quart d'entre eux devenant des utilisateurs fréquents.Les principaux obstacles à l'utilisation sont le manque de participation des autres étudiants (problème de « démarrage à froid »), les problèmes techniques (problèmes de connexion, problèmes utilisateurs) et les problèmes liés au temps.Les suggestions des étudiants interrogés visent à simplifier les moyens de se connecter, et à faciliter et valoriser la participation.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
