I will first explain a little bit in English about the project and the tools we used, and then Marina will talk in French about the pedagogy. This project is a French project. The theme of our project: we wanted to discover the planet of the adolescents, our students. But it was only an excuse to learn a foreign language, in a collaborative way. That was our aim. At the same time we wanted to develop the ICT-skills of our students by using different tools.
