It is a European mobility project for french teachers and heads of our network of schools in the south of France (Provence- Alpes-Côte-d’Azur region) - both real (as part of an Erasmus+ accreditation) in the European Union - and virtual in support of a digital platform using immersive virtual reality technology (Immersive Colab : https://immersive-colab.fr/ - Look at : https://www.youtube.com/watch?v=7Biz3RpCvAk). Our network of schools includes several groups that will move within different countries or schools. For each school that hosts us, we will carry out a half-day job shadowing of 4 to 8 teachers and heads on teaching practices based on the pedagogical approaches offered by cognitive sciences.
