Since in the year 2004 IES Emilio Alarcos School started to implement the integrated Curriculum within the British Council-MEC agreement, the importance of the English Language as the language for communication has been gradually increasing; together with the participation in international European projects focused on teacher training, Comenius projects, e-Twinning, Erasmus. Besides, during the last school years, a special effort has been made to invest and train ourselves in aspects related with ICT. This project aims at developing the modernization and internationalization of our school, meeting, at the same time, the needs of professional development of all the teachers in the school. The project pretends, therefore, to consolidate an already existing tendency in the staff of the school to integrate new teachers eager to develop the multilingual and European dimension of culture. The project, which will last a year, involves the mobility of six teachers with the following profile: 2 teachers will receive a linguistic training with the aim of joining, in the short or the long run, the Bilingual Project. 2 teachers, who are content, non-linguistic teachers, will receive methodological training related to their specific subjects or related to the content-language integrated learning of foreign languages. 2 language teachers will receive methodological training related to their subject. In all the cases teachers will attend training courses in prestigious institutions of England or Ireland specialized in this kind of teacher training. All teachers are committed to use Europass before the mobility, and to know e-Twinning virtual tools. Furthermore, they will spread their experience to all the teachers of the school, either in a plenary session, team work or disseminating it through other resources like web, blog, video or the media. The results envisaged will be a visible improvement in the motivation and training of teachers which will have a direct impact on the quality of teaching to students. Besides it will contribute to the international dimension of the school as teachers will cross borders between subjects and beyond the school walls. It will create, likewise, an atmosphere of productivity and collaboration for creative teaching. We envisage a relevant impact on teachers as it will create an environment full of enthusiasm and eagerness to increase collaborative work and a significant interaction with students. In the long run the potential benefits are obvious for us as we consider in the following years we will see changes focused on: A stronger determination on the part of teachers to improve their lessons taking into account the challenges the realities of our changing society poses for our students. A more international and globalized perspective approach to teaching that will allow them to cope with a complex world. A higher language/content-oriented approach to teaching following the main trend worldwide which is CLIL, especially in Europe. A bigger student-teacher-family interaction and collaboration as teachers will be more aware of the need to empathize with students to achieve our goals of empowering them. Raising awareness of the need of a European citizenship open to the world and the need for integration by bringing the real world into the classroom. In conclusion, our students in the long run will be more prepared to cope with a highly demanding future which includes key skills to find a place in society such as the ones mentioned before: digital competence, linguistic competence, critical thinking, autonomous learning or team work.
