The municipalities of Novéant-sur-Moselle (Lorraine - France) and Luleå (Norrbotten - Sweden) have been united by a cooperation agreement since August 5th, 2011. They intend to stimulate a European intercultural spirit with their young audiences and more particularly with the pupils of schools and local associations dedicated to young people. So, the project "Rhythm and Seasons" first aims at encouraging exchanges of experiences between both countries on subjects such as school timetables, the daily routine of a pupil or a young person within their family, educational and territorial communities. Two different countries where seasons, geography, spaces and the sociocultural situation contribute to bring a different contents both in formal and not formal educational offer. Therefore, through the exchanges of experiences, and thanks to the local specificities (cultural, natural, spatial and socioeconomic) new didactic tools can be used with the pupils and the young people allowing a better mutual knowledge between the municipalities. The project also aims at identifying new opportunities of cooperation between schools, non formal education associations of both partner countries. The participants will be at the same time the teachers and a group of pupils for each country; the staffs and the local actors of local authorities, partner associations and schools. Nine transnational meeting are planned, allowing every country partner to realize 24 mobilities, as well as two short-term exchanges of pupils in reciprocity. These exchanges will have as final purpose to develop didactic tools realized by all previously mentioned actors, including the pupils, according to the principle of a “living laboratory” where the final users also contribute to the optimization of the educational and didactic resources. The project intends to improve the skills of the participants; to achieve a better knowledge of the partner countries; to diversify the educational tools to the benefit of users at school or outside school; and to strengthen partnerships between the partner regions. The project aims also at developing and optimizing the services provided by the local authorities within the framework of the formal and not formal education.
