   • La baladodiffusion est ainsi utilisée comme outil à potentiel cognitif, parce qu’elle permet, relativement facilement, de diffuser un contenu audio ou vidéo qui peut, par la suite, être écouté ou vu à tout moment par l’apprenant. Par ailleurs, les responsables du projet rappellent que les étudiants l’utilisent également pour écouter des balados de chroniques audio comme celles de The New England Journal of Medicine, une des plus importantes revues en médecine au monde.

     Therefore, podcasting is used as a tool for cognitive potential, because it allows for the relatively easy distribution of audio or video content, which, as a result, can be listened to or watched at any moment by the learner.
