O POTENCIAL DAS ATIVIDADES CENTRADAS EM PRODUÇÕES DE ALUNOS NA FORMAÇÃO DE PROFESSORES DE MATEMÁTICA.

This article presents and discusses the design and implementation of activities focused on the work of the student as a strategy for teacher education in order to contribute to the development of content knowledge and pedagogical content knowledge in pre-service and in-service courses for mathematics teachers. We will provide different research contributions regarding the subject and we will illustrate our contribution to this area by describing the basic structure of tasks that we have proposed to grade 6 to 9 and high school mathematics teachers and the analysis of a specific task implementation. We will carry out an assessment of what we have learnt regarding the potential of activities based on the work of students in mathematics teacher education and regarding ways to construct them.
