Youth Exchange 2015: A tribe into the wild 20 Youngsters from France, Italie, Slovaquie and Portugal between 18 and 30 years old Le Viel Audon Welcome to the Viel Audon, a hamlet lost between the Ardeche river and the cliffs. Here, we can only come by foot, here, the time passes slowlier, here we seem to be alone in the world, here we make cheese, bread, sirups, marmelades and all kind of products, here the youngsters of the yoth exchange can learn how to feel good in group and how to develop their projects. 4 different structures work here (in fact, we can't do everything!), and we work on horizontal working and mutualized spaces, material and governance. The Association Le Mat is the one who is in charge of organising the youth exchange that aims to show to the youngsters that another way of living and thinking is possible! Thinking! it's the masterworld, since through all the projects and workshops chosen by the them, the participants will questionning themselves on the footprint produced by human being on the nature. In order to have true impact on the behaviour of the participants we decided to propose a full immersion in the nature, where they will sleep in tents,make firecamps, create, organize together, listen, play and share. Among all the activites the implementation of personal project is the core of the exchange. The youngsters will gradually discover their autonomy and self-confidence thanks to the active learning method of project-based education that will be proposed.
