Shall we introduce narrative investigation practices in math teaching?

This is a discussion of epistemological, methodological and theoretical elements of research in current Math Education and that of the teacher-reflective-researcher practice in contemporary society. The objectives of such discussion are: a) to introduce basic notions to understand the relation between researcher and the object of investigation; and b) to direct Math teachers to undertake research from the very beginning of their trawling. In order to achieve research goals, teachers in trainning can both study classroom dynamics through the testimony of the students as well as analyze meanings in practices of narrative investigation. It is recommended that such practices are incorporated to daily Math teaching and learning processes
