Personalization and Adaptivity. What Relation?

The complexity of the current educational context, that is, the fragmentation of knowledge and the diversity which characterizes the students in our schools requires new competences: the learner should develop skills in building significant network, the teacher should set multiple dispositifs that are connected to support learning. The personalization of the processes is certainly an answer, that is, the chance to develop different paths in which diversity is respected, but in which also the autonomy of the learners is fostered. For sure the problem is the sustainability of such path. Can adaptivity be a strategy in this direction? If yes, how and thank to what modalities?
