Our study is based on a diachronic analysis of the second year LES curricula from the 1990s to the present day (thematic, lexicometric analysis and analysis of didactic transposition times). The whole shows a regression of ecological knowledge in favour of the integration of hybrid knowledge linked to sustainable development (SD), a growing anthropocentrism and the opening of the discipline to social legitimacy. From this, we have drawn up guidelines for teacher training, in particular the importance of questioning the content of teaching, the relationship to knowledge, and of making the hidden curriculum explicit.}}
