Discussions concerning the teaching of sciences in the national context have assisted in the initial and continuing teacher training, as a contribution to the quality of teaching and learning. In this sense, this work explains a re-reading of the Study Situation (SE) proposal for the training of MST teachers, in dialogue with the critical pedagogy of Henry A. Giroux. The research, the result of a dissertation, was developed in the Integrated Center Florestan Fernandes of the Settlement Terra a Vista, located in Arataca/Bahia, constituting of the following instruments: a) Pedagogical Political Project (PPP); b) Questionnaires conducted with twelve teachers of the school; c) Interviews with the coordinator, the school director and three teachers participating in the course. Data from all instruments were analyzed in the light of the Discursive Textual Analysis (ATD). Through the stages that have been developed, we can perceive approximations from the theoretician adopted with the SE and the formation of teachers of the MST, as well as relations with the critical pedagogy and with the pedagogy of the MST.
