This article presents some critical reflections about traditional concepts, which determine the polices related to performance, evaluation and teachers’ professionalism in our country. First of all, there is a look over the meanings which can be found in proposals for professional improvement, as strategies for teaching activity normalization, and the necessary legitimization of non-reflective, instrumental and dependent teachers’ image. Second, it is suggested that an alternative concept make professionalism meaningful, through the permanent formation, as a resource for the teachers to think of themselves in the exercise of a historical-cultural teaching activity.

The current article deals with Lasallista pedagogy, considered as knowledge, locating us in Colombia between 1915 and 1935, from the epistemic dynamics that allowed their composition: the reflexive preparation of the pedagogical experience itself; the interaction between pedagogical practice and knowledge already constructed or in process of construction and the movement and socialization of the pedagogical knowledge. Each of these dynamic is supported by actions of thoughts that reveal the production of a set of intellectual preparations about a field, a practice and about an object of knowledge which indicates that Lasallista pedagogy can be understood from an epistemological horizon, because it is on the base of knowledge exercises that are sensitive to be socially and academically recognized as such.
