The Use of Technological Tools to Support Argumentation in Mathematics

Abstract

The aim of this workshop is to discuss with in-service teachers and teachers in initial training about the use of dynamic geometry software, spreadsheets, and generative artificial intelligence as tools to assist problem-solving processes in school contexts. The methodology of the workshop is practical and experiential, so a series of problems are proposed to be solved in large groups, so that as the problem-solving process progresses, the underlying theoretical and didactic concepts are also clarified. This way, the dynamics of the workshop itself provides teachers with strategies for managing the activity from a teaching perspective. Although the workshop uses a digital medium, this workshop is related to previous activities carried out in COBISEMAT on paper. Thus, the discussion allows for the comparison and contrast of the material media of “paper” and “software”, enriching the discussion in the mediational dimension. Activities are organized according to a “menu” approach, with initial motivational activities serving as “starters” and development activities as “main courses”. Depending on the appetite of the participants, there are also additional “dessert” activities, and for the bolder ones, there is a final round of activities in the “alcoholic drinks” section.
