Considerations on teaching methods to deepen student argumentation through problem solving activities

In this research project we evaluate the Toulmin model to analyse students’ mathematical arguments (Toulmin, 2003). We use this method to analyse a teaching episode in which the sum of the interior angles in a five-cornered polygon was discussed. This episode took part in a mathematics lesson in junior high school, Japan. The analysis highlights students’ difficulties to understand ideas of their peers, and how these led to an improved level of discussion.
