A model of the instrumentation process in dynamic geometry
Résumé
The present study investigates students’ instrumentation processes while solving open geometry problems in a dynamic geometry environment. It aims at developing an analytical and comprehensive model of students’ conceptual schemes and strategies built around the use of the tools available in DGE. The study was conducted in a grade-10 math class in a Lebanese school. Data were collected through whole-class observation with analysis of paper-based data and closer observation of 12 pairs of students. The analysis focused on the instrumentation process that occurred during the construction and manipulation of geometric figures. The results suggest the development of a three-phase model of the instrumentation process.
