"""Mission: Europe"" project arises from IES Pérez Galdós experience during over six years in carrying our long-term mobilities for students within the frame of different European Projects. Its main aim is to foster the Spanish language as a means of communication in Europe while offering students from other European countries, who are studying Spanish as an L2 or L3, the chance to improve their Spanish language knowledge and to learn about Spanish culture. We also focus on the cultural asset of having this type of mobility in countries where CLIL or EMILE are being implemented, like in our school, and where our students may use Spanish as a lingua franca for communication while improving their level of other foreign languages such as French, Italian or English (or even learn an L3 such as Portuguese or Finnish). Furthermore, we consider that the long-term mobility concept provides per se a huge opportunity for personal growth and learning for both students and teachers who participate in it while having a tremendous impact on the hosting institutions.Within our project our travelling teachers and students will become natives of the target language of the project 8Spanish in this case, for IES Pérez Galdós participants) and they'll be able to share their knowledge of Spanish language and culture.Students and teachers who will visit us for two months will be French and Italian language natives, and in the case of Portugal and Finland, if not native at least they'll have an excellent level of English, either because they've been trained in CLIL or because they've had a good EFL training. Furthermore, we expect students participating in the mobilities to assume the roles of becoming peer trainers, by giving lectures and workshops to students of other educational levels in their mother tongue or in English (Portugal and Finland) about the situation of specific values in their countries. We have chosen the topics of gender equality, environmental awareness, human rights, coexistence and mediation, health education and responsible consumerism. Finally, the long-term teaching mobilities will be carried out simultaneously to the long-term learning mobilities of students."
