The IES A Sangriña, located in the seaside town of A Guarda (Galicia), has been developing since 1992 an intense activity in the framework of European Educational projects. The cooperation with other EU institutions has made the educational community to overcome the several barriers imposed by its peripheral location, helping in this way to avoid problems such as school dropout and youth unemployment. In this way, the making of a sense of European citizenship, through a constant flow of teachers and students from other partner institutions, and the promotion of foreign languages learning and teaching, have been some of the main priorities in the philosophy of IES A Sangriña. As a result, the present project has a main purpose, the observation of new methodologies in the teaching of foreign languages, both being understood as pure subjects and through the CLIL (Content and Language Integrated Learning). In our case, a teacher will be sent to a French school in order to follow-up the teaching of the Spanish language as a foreign language. And two of our teachers will be sent to two different British schools to deepen and observe the teaching methodology of their subjects being taught in English (in this case Physical Education and History). At the same time, the contact with other schools will provide participants with new perspectives and initiatives for European cooperation, mainly in the framework of Erasmus+ program. All the participants are active members of the international team of IES A Sangriña, and for this reason, they have a remarkable and wide background to tackle a project like this: an active and tolerant European consciousness and, above all, the certainty that the teacher training is essential to provide our students with a comprehensive education and future prospects. The activities that will be carried out in their host schools are observation and direct participation in teaching activities, both as complementary and extracurricular teaching. Further meetings are planned with the teacher staff, educational authorities, parents associations and other institutions in the area with a different educational offer. The methodology of this project will be immersion in the life of the host school, so participants could feel another member of the staff. The expected results are acquiring new perspectives, methodologies and teaching approaches, improving communication skills (linguistic and social) and the opening of new avenues of European cooperation. This will have an impact at all levels: individual, because that will improve the skills of teachers and acquire new tools; local, both in the host school -by feedback-, and in the sending school –where students will benefit from the professional improvement of teachers involved-; and, more generally, an impact on the educational community of both countries because of the results of this experience will benefit future participants. The long-term benefits will derive from the above mentioned impact: foreign language training is the best way to fight against the low level that Spain has always had in this area, and only this way of improving the skills of our teachers can overcome the present situation.
