GENERALIZATION PROCESSES IN THE TEACHING/LEARNING OF ALGEBRA: STUDENTS BEHAVIOURS AND TEACHER ROLE

We give an overview of the literature on generalization with particular reference to the studies about the students’ ways of thinking in the development of generalization in algebra. We discuss the teacher’s role in guiding students to face algebraic generalizations and we report on our methods and tools to improve teachers’competence in teaching this kind of tasks in a socio-constructive perspective.
