Since the 1970s a heterogeneous group of non-disciplinary topics for education has emerged, such as health education, environmental education, sustainable development education… The institution defines them as transversal topics and since 2013 they are called « parcours éducatifs » or educational journeys. The notion of education involves that of the subject as a whole, with his/her affective, ethical, political and cognitive dimensions, and that of education’s capacity to empower. The preposition « à" is usually a fig-leaf for “pour” or “for” such and such an international institutional. To put in question these different “éducations à” is to think about the relationship to knowledge and to its legitimacy, and rethink school disciplines and their didacticism. Such questioning then abuts on the issues or questions called “socially acute”. This paper studies in succession the emergence and the specific characteristics of both these fields in order to compare them, take stock of their convergence, and try to see beyond them.
