Abstract

The research focuses on the forms of human collaboration demonstrated by teachers and secondary school students who participate in an experience of simulator development with GeoGebra (SDG) in which mathematical modeling processes are involved. To analyze the collaboration in this activity, we relied on the idea of subjectivity coming from the Theory of Objectivation (RADFORD, 2014). Through an interpretative analysis of the moment in which a student communicates to others the technique used by them to build a semicircle with GeoGebra, it was possible to identify the presence of responsibility, commitment, and care for the other, as the three forms of collaboration produced in the SDG. In addition, the analysis identified how one of the teachers promoted some of these forms of collaboration in the students. The findings suggest that the way of managing technique communication, individualistic culture in school, and the students' resistance to change were the three aspects that influenced the manifestation and promotion of these forms of collaboration.
