CONAPEDE, a transnational research on outdoor education : To problematize, through an analysis of controversies in various disciplinary fields, how actors on the ground apprehend the concept of ‘nature’ in outdoor pedagogies, in order to identify its political, social, and philosophical implications ; To co-construct evolving interdisciplinary pedagogical and didactic approaches on the concept of ‘nature’ for multiple school levels; And to train teachers by supporting them in the experimentation and evaluation of new pedagogical and didactic approaches.
