Abstract
This article discusses a doctoral research on the training of Mathematics teachers, analyzing how future teachers perceive themselves as subjects under training within the signification movement of the teaching activity. Grounded on Cultural-Historical Theory, it describes a formative experiment conducted with undergraduates of a Mathematics Teaching degree. From three episodes analyzed, the results highlight aspects that allowed future teachers to perceive themselves as subjects under training, such as changes in the motivations for becoming Mathematics teachers, understanding of teacher education as an ongoing process, and changes in the quality of teaching activity.
