Student teachers' proofs and refutations on cyclic quadrilaterals

Résumé

We follow and analyze three teacher students’ behavior while they engage in a task with the goal of the reinvention of the characterization of cyclic quadrilaterals in terms of their opposite angles. We show how, during the exploration of the problem, the teacher students go through cycles of proofs and refutations, in the sense of Lakatos, and we discuss the role of the teacher educator in supporting and conceptualizing these processes. Our results may have the potential to be used in designing mathematical activities aiming at scaffolding teacher students´ knowledge for teaching proof.
