Revista Virtual de Química, Niterói, v. 7, n. 3, p. 1007-1029, maio/jun. 2015.e- 1984-6835http://repositorio.bc.ufg.br/handle/ri/15807The achievement of the practice of freedom covers an essential task which comes up when the lesson is structured from participative actions that lead to freedom of expression and critics, without the imposition of knowledge to students. We report the praxis in the sphere of Graduation in Chemistry, for supervised academic training course. This topic has been used as theme by the problematizing teaching with High School students. The proposition we have developed through a problematizing bias has shown to be relevant for the students as well as for the interns who took part of the activity. The process added to the ensemble of knowledge of students and interns, a method of studying and a method of critical reading of reality with relevant consequences for the formation of both interns and students as critical citizens.porAcesso AbertoProblematizing teachingTeacher formationTeaching of chemistryEducação problematizadoraFormação de professoresEnsino de químicaArtigo10.5935/1984-6835.20150055
