The staff mobility project is addressed to Marco Belli High School,which includes two branches: Social Studies Lyceum and Language High School. The curriculum of the two branches aims at stimulating and developing students' potential, at the acquisition of skills and abilities necessary to face the challange of University Sillabus, working life, active citizenship. The project responds to the following needs: expanding the CLIL practice, forming a network of teachers that will support the call for international cooperation that already characterizes the school, extending the idea of an active school which works on international projects through cross-curricular topics. The project aims at creating stronger links between our school and other european schools, where today's student and tomorrow's citizen are at the centre of the learning process and of the intercultural dialogue. There are six participants in this mobility staff project, the school headmaster is one of them. He will be part of the project, being a strong supporter of the internationalization process of the school and of the centered- student method. The headmaster will also help teachers to reflect upon their role as leader, learning the process of drawing out the latent talents of the individual. Among the teachers also one of them teaches a foreign language (french), the ramaining four teach historical, philosophical an literary subjects. The chosen teachers respond to the aim of extending the CLIL methodology and stimulating the school teachers to take part in international projects, so that the team work among our staff and european school staf become a common practice. Three teachers and the headmaster will follow teacher training courses focusing on language and methodology at an English partner with consolidated experience in this field, two other teachers will follow one week course in Spain organised by an Italian association working on the concept of European citizienship. There are four steps in the project: identification of the school needs, identification of the participantsfor the staff mobility project and cofirmation that their needs corresponded to the ones of the school. Choice of the partners and training activities that better suited our needs, dissemination of the projects' results, expansion of goo practices. The espected results are: enhance teacher's motivation, acquisition of the concept of long-life learning; identification and sharing of the school needs and mission; improving professional qualifications, skills and practices; extending CLIL methodology; extending a network of links with other european schools and school partnership, breaking boundaries and prejudice towards what is unknown; acquiring a more active methode of teaching based on innovation and creativity to ensure the effectiveness of the "triangle of knowledge" -education, research, innovation; reassessin 'teacher beliefs and attitudes' in the light of current trends in methodology. Long term objective of this project, for both, teachers and students, is the gaining of planning skills either in education, training and professional path, the gaining of the concept of active citizienship which means considering each person as aprotagonist of his/her choiches, the habit to work in a european perspective.
