Panorama histórico da formação dos professores de ciências

This article intends to understand how the Laws of the Guidelines and Bases of the National Education (LDB) and respective amendments has contemplated the training of teachers of sciences and biology teachers pointing out the main problems and implications, from a historical perspective. Through documentary and bibliographical analysis it was highlighted that there is a historical heritage in the degree of the “3 + 1” model, characterized as an appendix of the bachelor’s degree, leading to the non-identification of the profile of the trained teacher; the knowledge separation in scientific and pedagogical of this model further fragmented the curriculum of the course; the poor quality of the teacher license (degrees) created mainly through private initiative after LDB/96 formed disqualified teachers hindering the learning of the teaching. Ultimately, current modifications in LDB went back by attesting to the possibility of assigning teaching to people with “notorious knowledge”. The relevance of resorting to legal texts is highlighted, since the way in which teacher training is approached also reveals the importance attributed to this field by the set of social groups as a whole.
