Education
- Developer42Fondée par Xavier Niel. La méthode 42 repose sur “apprendre à apprendre”. Les projets réalisés en autonomie ou en groupe doivent être débattus puis corrigés par d’autres pairs qui n’ont pas forcément suivi la même progression. Ce sont des moments d’échanges où l’on doit expliquer ses choix. Ils permettent de consolider ses apprentissages personnels et d’apporter des connaissances à la communauté.
