This study aims to discuss the construction and implementation of a proposition to implement a mandatory curricular recommendation and to teach the Special Theory of Relativity in class, with focus on the protagonist of the change: the teacher. Therefore, this study aims to give subsidies to answer the question: how does a teacher who wants to implement the prescribed differentiated curriculum uses his teaching practice to reconstruct and re-signify the new curriculum? To answer this question, we developed qualitative research, specifically a Case Study. The analysis of the data indicate that context of development of this study, where the teacher participated as an author of the pedagogical process, allowed him to reconstruct the curriculum, choosing what issues should be highlighted and abandoned to achieve the pedagogical objectives.
