I have being working with dynamical geometry in a Euclidian Geometry course. The environment works very well for conjecturing. But for proving the results that are visually stable... that is another PROBLEM.
So I am interested in research results that focus on the question: how to promote in such environment ÃÂforms of thoughtÃÂ which could empower students in creating proofs. If too general , maybe some key words would be: theorems in motion, recasting of classical theorems, reasoning beyond indutive and deductive... Thanks for your attention Maria Alice
