Abstract
When envisaging systems for direct and distance learning, the selection of media is increasingly complex, given the rapid evolution in information and communication technology. The present article proposes a generic definition of the concept of a mediated learning environment that is based upon observation of the technological components of the media: infrastructure, means, support, and message. This definition is useful in facilitating media selection and the formulation of pedagogical « messages » according to the different learning environments into which the learning systems fall, the types of learning systems (cross-boundary media and interactive multimedia), and the type of learning activities (consultation, production, or learning management). In this concept of mediated learning environment, two principles of media selection function effectively: the principle of negative selection and the principle of supplantation. These two principles and this definition could serve as the basis for elaborating a selection model for mediated learning environments. La selection des medias pour la conception des systemes d'apprentissage et de tele-apprentissage est de plus en plus complexe compte tenu de l'evolution rapide des technologies de l'information et de la communication. Le present article propose une definition generique du concept de media d'apprentissage qui repose sur une observation des composantes technologiques des medias : les infrastructures, les vehicules, les supports et les messages. Cette definition est utile pour faciliter la selection des medias et la formulation des messages pedagogiques selon les differentes situations d'apprentissage dans lesquelles les systemes d'apprentissage s'inscrivent, les types de systemes d'apprentissage (plurimedias et multimedias interactifs) et le type d'activites d'apprentissage (activites de consultation, de production ou de gestion de l'apprentissage). Deux principes de selection des medias s'operationnalisent bien avec ce concept de medias d'apprentissage : le principe de selection negative et le principe de supplantation. Ces deux principes et cette definition pourraient servir de base a l'elaboration d'un modele de selection des medias d'apprentissage.

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.
