摘要：This article is about being a teacher training in the biological sciences and chemistry degree courses at a federal institute of education. It results from research, whose objective was to develop a training proposal that focuses on the articulated planning between some disciplines offered in the teacher trainers and on the development of the supervised curricular internship (ecs) as a viable element of the articulation between the teaching, research and extension tripod and the future licensee’s field of work. This is a qualitative research carried out by a group of professors working in undergraduate courses and with research on initial teacher training, in which the narratives collected in portfolios prepared by the graduates of the biological sciences and chemistry courses and the authors’ narratives based on observation of teaching practices carried out in the classroom and in research and extension projects, of which they are coordinators. The results signaled that the collaborative planning and the materialization of the teaching/research/extension tripod having as object the pedagogical situations of the school of basic education in the process of the sci, promote an articulated formation between the diverse disciplines of the training course and approximation with the professional context , the school of basic education .
