Simulazione in ottica geometrica

Several papers have demonstrated that the student constructs conceptual schemes based on everyday life experience (preconcepts) constitute an obstacle for the scientific learning. So it is important to find strategies to make easy the transition from the everyday life schemes to scientific schemes. In this paper simulations are used as strategy to overcome some preconcepts in geometrical Optics: the first part deals with the historical root of the preconcepts; in the second part some didactic modules containing simulations have been developed.
