             <p>Avec l’apparition du web, c’est la nature même des savoirs sous toutes leurs formes qui a changé tandis que l’écriture réticulaire devenait accessible aux publics les plus divers. Ceux-ci ont redéfini les conditions de la parité et de ce fait l’université est entrée dans un nouvel âge. C’est ce fait majeur, massif et à bien des égards stupéfiant qui requiert le développement des digital studies prôné par la ministre de l’enseignement supérieur et de la recherche.</p>
             <p>L’enjeu majeur représenté par les enseignements numériques vient rationnellement après celui de la recherche et des études numériques. Il s’agit d’impulser une dynamique qui repense les rapports des savoirs à leurs supports (dont les MOOCs) avec les universités et les institutions académiques, et qui, par la recherche, redéfinisse leur rôle dans ce nouveau contexte.</p>
