This study presents the educational formative potential from the experience with PIBID, from practical and conceptual points of view of teacher trainers participating in the above mentioned program and in the teaching fields of Biology, Physics, and Mathematics of three higher education institutions in southern Brazil. Semi structured interviews were done with nine professors. The data, analysed through the light of Textual Discourse Analysis, point out that the experience in the PIBID helps to rethink the teaching degree curricula in these institutions, getting teachers closer to school reality and allowing the deepening of themes that impact the formation of teaching degree students. The study also indicates that for teacher trainers, the relationship between the Program´s contributions and their professional development as professors is still unclear.
