The international Youth Exchange "Paris. Berlin. 9.11" will bring young people from four different european countries together and the opportunity to get in touch and meet at eye level. The participants will be involved during and after the exchange so they have a very active part at this project. This supports their organisational, communicative, linguistic and intercultural competences. Through a peer learning process they have the opportunity to design the exchange with their own ideas and wishes. The participants will discuss about extremism in european countries and how it is present in media and the public. By this they can see how extremism is handled by society, and how extremistic groups use different media platforms for their own interests. They will talk about their experiences in a creative way and regard them within social structures. The participants will take up their experiences during the youth exchange and present the results of the workshops at the end of their time together.
