This project provided for the meeting of about twenty young people aged 15 to 17 for 2 weeks. It followed a youth exchange that took place in 2019 "Act trough theater". The evaluation of the first session had shown that this exchange had had an extremely positive impact on the participants. Whether in terms of civic awareness and their desire to become actors in society; in terms of self-esteem, autonomy or mobility, as well as confidence in their abilities. We have therefore chosen to renew this project with the aim of making it evolve according to the various remarks of the partners and participants, to allow them to go further. Active participation and the theater of the oppressed seemed to be means that concretely affected young people. Keeping our philosophy, that of popular education and living together, we imagined this second edition, co-constructed with a local association, "Magnétophonie". Following a discussion of the results of another action, we had the idea, with these two radio professionals, of using this medium as an approach for themes that are not easy to address. The teenagers had the opportunity to stage their fight and their questions in an original way, and proposed solutions to these problems in their own way. A final performance took place, it was open to all. This project took place in a small village in Haute-Saône, which in summer represents a certain dynamism in the area. This is exactly what we hoped for. All the participants took responsibility for taking part in collective life, whether for preparing meals, cleaning shared spaces, being a source of proposals for activities and free time... and of course, for the heart of the project, with participation in the various modules dealing with cooperation, peace, injustices of all kinds. The youth exchange is a very important and extremely powerful tool when it comes to dating. Without this project, these young people would never have crossed paths, would not have shared a common culture during these fifteen days, would not have cooked together, exchanged together, would not have been able to compare their ideas. Without this project, these young people from different backgrounds, with different social statuses, would not have been able to experience this interculturality, would not have been able to dream, together, of a society that resembles them. In short, they could not have developed their creativity for a fairer world. Our objectives were therefore the following, for this action and more broadly: - Reaching marginalized young people and enabling the participation of all in our actions; - Promote diversity and intercultural dialogue as common values of tolerance, and respect for human rights; - Encourage young people to think critically and make them aware of their power to act on the society, through the tools of theater and radio; - Enable peer learning for both partners and participants. - Work and develop international cooperation for young people with fewer opportunities
