Abstract: Our aim is to show how the use of dynamic geometry software GeoGebra and the mentoring role of the teacher are helping to design an interactive tutorial system, which is intended to support students in developing its mathematical skills in high school. Our theoretical framework integrates the instrumental approach of Rabardel (1995) and the notion of orchestration from Trouche (2004) to jointly investigate the interactions between students, teachers and the milieu. From an experiment conducted with real students, we analyze the solving problems strategies in plane geometry to explain how the joint use of traditional and instrumented techniques converge for ...
