Teaching in context the importance of revealing implicit obstacles for teachers

In this paper, we present a research work whose main objective is to reveal the opinions of active teachers about the implementation of a didactic proposal for Natural Sciences in Context, with an interdisciplinary approach, linked to a project-based methodology. The research shows the advantages and limitations indicated by teachers who did not apply the proposal with their respective students, and the opinions of those who did implement it in their classrooms. The latter showed social representations that are rooted in the educational community and would act as implicit obstacles when implementing innovative proposals.
