This research proposes a framework based on the Theory of Conceptual Fields to organize training processes of future teachers and to explain learning in a social sphere, such as those related to the teaching of scientific concepts. The 'conceptualization' that is developed by these teachers is addressed through qualitative methodology, specifically through case studies. The cases examined vary in their approaches of applying the conceptual framework, which was implemented to serve as a guide to orient didactic intervention. However, in all cases mobilization of elements of their schemes were given to teach scientific concepts.
