From research to classroom: proposals

Since the past ten years, the “Math Education Research Group” of Catania University carries out activities both on research and on class experiments with/for teachers and students. Particular attention is given to teaching/learning geometry with technologies. These activities start with the search for new properties of elementary geometry that are then used to design proposals for innovative teaching in secondary school; then, after writing with teachers the classrooms worksheets, a teaching experiment is conducted in class and the results (in terms of students protocols, videos, teachers log books …) are analysed. We present here some of these activities.
