Analysis of argumentation processes in strategic interaction problems

In this study we use Habermas construct to analyse argumentation processes related to strategic interaction problems, i.e. problems in which a player tries to figure out what the other player(s) will do, and to choose the best strategy between the possible ones. These problems provide suitable environments to develop and analyse students’ planning and control processes, of a paramount importance in mathematical problem-solving. We will integrate Habermas construct with specific theoretical tools to frame students’ processes with respect to planning and control, and we will analyse excerpts from a classroom discussion in grade 4, in order to highlight specific features of the argumentative discourses, brought to the fore in strategic games.
