The Persuasive Power of Refutation in Collective Argumentation

Abstract This study is framed in mathematical classroom argumentation. Its purpose was to identify functions of refutation of claims in collective argumentation. This was done through the implementation of a theoretical methodological approach based on the argumentative model of Toulmin (2003), which allowed the study of the collective argumentation and their structures within the classroom. Along with the theory convictions, we found how refutation has a persuasive power on the student's arguments, with this being another function of refutation.
