Tensions entre projet didactique et injonctions pédagogiques : analyses praxéologiques en Éducation au développement durable.

The integration into French school curricula of education for sustainable development (ESD) at all levels and in all disciplines, is a major challenge for the school system. This integration is officially associated with a dual injunction questioning traditional disciplinary didactics and pedagogical renewal. The didactic projects and pedagogical modes that have emerged for the last ten years in the context of such an ESD create both didactic and pedagogical difficulties that teachers must face. Such difficulties are a source of tension between these two levels of didactic co-determination and under the pressure of strong pedagogical injunctions, didactics tends to fade behind pedagogical issues.
