Ways of using multimedia web-resources on wave behaviour, with the aim of integrating lectures, experimental activities and individual study are illustrated and discussed. The focus of the paper is on the advantage of using animations and simulations as tools that facilitate the cognitive path from observing real experiments to constructing physical interpretations and as collections of virtual situations allowing lab potentialities, […]
