In this special session, we will focus on different variables influencing the mathematics teaching- learning process. The meeting is organized around four topics. The first part will be devoted to presentations of different theoretical models related to teachers' professional activity and professional development. The second part will be devoted to presentations analysing aspects of the use of technology in the mathematics classrooms, to show that, for each mathematical content and each student, there is a kind of computer environment that may help the student learn the content. The third and fourth parts of the special session will have the format of panels. In the third session, panellists will present different didactical theoretical models useful to analyse students' problem solving productions; from the presentations, it will be evident that the theoretical models focus on complementary aspects of problem solving processes and offer different viewpoints. Finally, the fourth session will be devoted to analyse the possible influence of national or international external assessments of students' performance on the daily activity of teachers and students.
