Es.Col.Az. is a network of artists who in the last years have been responsible for the conception and realization of independent courses in the performing arts in Portugal, aiming at the problematization of power/knowledge relations in contexts of learning and knowledge production, having the body and the collective as a focus. This network has been progressively formed through a series of meetings, having as a horizon the continuous sharing of researches focused on the conditions of learning, on the idea and modes of school, and how both are matters of investigation themselves, either by the realization of courses like those in which the artists/researchers of the network are involved, or by the rehearsal of the theoretical reflection that each one makes about those experiences.
