Roland Garros High School is located in Reunion Island which is unique in that it is part of both the Indian Ocean and the European Union. However, geographical distance and insularity are strong obstacles to the students ambition and to international openness. Our project is part of sustaining and developing our first experiences of European openness for the teachers and the students.Our school must continue to make it clear that international openness is not only a project or a temporary goal, but a regular source of enrichment from organisational, professional and educational points of views, as well as a constitutive element of our school's policy. We want to develop and promote innovative practices in language learning building on the skills acquired during staff mobilities. The teachers selected and trained according to their subject will be the driving forces of this innovation. This team will have to develop co-working, colaborative strategies and teaching in a foreign language, but also teaching in non linguistic subjects with the help of innovative activities in the three schooling routes (general, technological, and vocational). To do so, our staff must get an efficient training, thanks to mobilities in language schools (one in in Spain and two in Ireland), in training centers for teachers (two in Italy and three in Finland) but also two job shadowing in Germany. The teachers will have to observe and analyse european professional practises concerning innovative projects and how the other countries deal with school dropout. Some of the teachers will sit for a language certification that would enable them to teach their discipline in a foreign language. Our internationalization strategies must be enriched from exchanges with European partners. Through mobility, we want to improve our ability to carry out projects to consolidate our openness and outreach to the world.
