This project is the result of a multilateral school association with the aims of elaborating, investigating, teaching and exchanging knowledge on the topics such as, tolerance, gender equality and peaceful resolution of conflicts. The World Wars and the period between them will be the source of information from which teachers and students will base their investigation to find the tools to resolve armed conflicts without violence. To focus this research, it will be of the most vital importance to praise democracy and respect as the basis for human understanding. There are sixcountries and schools involved: IES Miguel de Cervantes (Spain), Malonstranske Gymnasium (Chezch Republic), Liceo Scientifico Statale (Italy), Kongsberg Vigederaende Skole (Norway), Durham Johnston Comprehensive School (England), Gürpinar Imkb Teknik Ve Endüstüri Meslek Lisesi (Turkey).

They will be grouped in teams of five and will be in charge of one of the topics proposed. Non-linguistic subject teachers will coordinate and check the work done by their students and they will also attend the meetings organized for each thematic area. Finally, students´ materials -videos, pictures, essays ,graphic materials, etc. will be used as the contents for our products: Clil units on the five main topics that teachers and coordinators will elaborate using students´ investigations and materials. Display panels with the final conclusion for each area. A magazine which will gather all the information displayed on the panels. The creation of an organization that will analyze the final results and conclusions reached in our last meeting. This project will involve all our school communities and will stand the test of time thanks to the Clil units that will be published in English and Spanish. Our results will be made available and free for any school to use in the future. The digital magazine put forward by the organization will also help ensure that our project endures and develops the values we want to transmit: tolerance, democratic principles, peace and equality among countries.
