Argumentation in the mathematical modelling cycle in the classroom
Résumé
Although there is extensive literature in modelling and argumentation, the joint approach to argumentation and modelling is very scarce in the literature. This article accounts for the development of argumentation in the different phases of modelling that students go through in the mathematics classroom. Based on an experience of professional teacher development, the analysis of three cases of teachers is presented to promote modelling and argumentation. The results of this study indicate that an argument structure with rebuttals in modelling tasks does not ensure complex mathematical connections.
