Resumo(s)
We aim to characterize how prospective teachers perform in defining and classifying quadrilaterals through
working on exploratory tasks. Data was gathered from the participants’ reports and portfolios. Results show
most understood the meaning of defining and presented correct definitions, using properties they previously
ignored, and showing comprehension of the underlying concepts. They produced economical definitions in few
cases, and performed better in inductive than deductive reasoning. The classifications showed conflicts between prior classifications and structural criteria that rules a geometrical classification. The exploratory work allowed participants to construct their knowledge in a meaningful way and reflection played an important
role in becoming aware of personal preconceptions and knowledge.
