La propagazione rettilinea della luce: una unità didattica per la scuola media

This is a detailed report of the study of the basic properties of light propagation with a middle-school class of 12 year pupils. It required about 20 hours of classroom time. The pupils performed experiments on the linear propagation of light and on the reflection on plane and concave mirrors using simple apparatus. The interpretation of the phenomena gave them the opportunity to apply their mathematical knowledge extensively.
