The mobility project aims at supporting the training needs of Liceo Cagnazzi: that has been engaged both in the development of the international dimension of education and teachers' training for a long time. The specific objectives of the project deal with the meaning of mobility as a possibility of comparison, didactic and methodological innovations in humanistic subjects' teaching and the development of linguistic competences with a particular attention to didactic approaches which are no longer frontal but collaborative and cooperative ones. Both objectives are coherently integrated and aim at the production of materials and resources (didactic modules, parts of curricula, evaluation schemes) to test in teaching activities and to share with colleagues through the establishment of common practices, also thanks to WEB 2.0 instruments. The planned activities are of two kinds: a)Job shadowing periods for 6 teachers in a French secondary school (2), an ex-Comenius partner, in a German secondary school (2), cooperating with a training centre for inexperencied or on duty teachers of humanities and in a Belgian school (2), at a high level of internationalization and specialized in the teaching of Latin as a dead language. b) training courses in English for 4 teachers of non linguistic subjects in an English training school specialised in CLIL methodology. These kinds of experiences will contribute to improve workshop dimension, a collaborative approach in teachers, both primary aims in a didactic activity based on competences. The expected impact implies a better extracurricular plan, the development of linguistic competences, of a greater interest in innovations, of good practices of participants who will spread their experiences among students and colleagues of their schools and of other secondary schools through the WEB (Moodle, social networks, blogs). It is also planned the development of a set of monitoring and evaluation instruments that will allow the certification of the competences for the participants and the records of the experiences, positive effects on the students, innovations, a greater mobility for students and teachers, further possibilities of ERASMUS PLUS partnerships for the school.
