Interdisciplinary Lesson Study in Italian High School focused on energy transformations

This research focuses on the educational experiment of Interdisciplinary Lesson Study, carried out with 15-year-old students in Italy on the energy transformations. The teaching was carried out following the IBSE model of 5E and involving teachers from several disciplines. The theoretical lens used to read the data is the Lotman’s idea of Semiosphere revisited in the educational context. It seems that collaborative teaching processes make teachers aware that asymmetry between disciplines can be an engine of knowledge. Moreover, these processes can also improve teaching disciplinary actions.
