We present some experiments with pre-service and in-service math teachers which show how the use of a good drawing with a dynamical geometry system sometimes "hides" some evident properties and therefore induces to miss some conjectures and to produce "proofs" with bugs.

Abstract
We present some experiments with pre-service and in-service math teachers which show how the use of a good drawing with a dynamical geometry system sometimes "hides" some evident properties and therefore induces to miss some conjectures and to produce "proofs" with bugs.File allegati a questo prodotto
