GeoGebra simulations for Feynman’s sum over paths approach

We present a collection of interactive simulations meant to complement the educational approach to quantum physics in high school developed since 2013 by the physics education research group at the University of Pavia. The collection, organized as a “book” within the online repository GeoGebra Tube is intended primarily for being used by physics teachers wishing to deepen their understanding of Feynman’s sum over paths approach. The simulations represent several problems of physical interest, and aim at clarifying different aspects of Feynman’s model. The collection has been used as an educational tool in the context of the IDIFO-6 Master coordinated by the University of Udine, and encouraging indications have been collected. In particular, the use of an open-source software which is very widely known and used in the community of teachers may encourage them to produce their own example simulations, or make easier for them to modify the existing ones according to their preferences and needs.
