The LeA network is the living space of the "lieux d'éducation associés à l'IFE", translated into “AeDeP” at FIE (standing for Associated educational Design-experiment Places at the French Institute for Education). Each AeDeP, lead by a team of research workers and local practicioners, raises a research question, thus contributing to reconstruct our ways of learning and teaching. This scholarly blog is therefore a collaborative working space to bring together hypotheses, to reflect on practices, to highlight innovative experiments and to share the ressources produced by these novel interactions between researchers and teachers.
