Institut Can Puig is a state secondary school located in Sant Pere de Ribes, 40 km. away from Barcelona. In our school we have 578 students and 57 teachers. We teach compulsory secondary education, baccaulareate, vocational studies related to business management and a Program of Training for pupils with special needs who follow post-compulsory studies. The main objectives of the project "Getting the most out of multilingualism" are the modernisation and internationalisation of our school through the implementation of CLIL, consolidating our current supply and offering new subjects to other levels, and to improve in the design and management of the international projects we started in 2014-15. Six teachers will participate directly in the project: he Head of the Technology Department and ICT Coordinator; the Head of the Visual and Art Education; the Head of the Foreign Languages Department who is also the coordinator of the project, a psychologist who is currently the tutor of Training and Labour Insertion Program for pupils with special needs; a Social Sciences teacher and finally an English and Social Sciences teacher who belongs to the driving team of GEP (“Group of Multilingual Experimentation”) and the promoter of CLIL in our school. The mobility activities we have chosen consist of five structured courses which include visits to secondary schools and one study visit which includes job shadowing: two structured courses focused on CLIL, one for Science, Maths and Technology teachers and the other one for Humanities teachers; one course related to fluency and English development for teachers; one course related to methodologies for English teachers who work with pupils with special needs; one course of design and management of European projects and, finally, a study visit with job shadowing activities in Finish schools.The methodology will be based on the creation of a work team with regular meetings and virtual platforms to exchange materials and experiences and work cooperatively, paying special attention to the dissemination of the results throughout all the educative community and through the networks which already exist as the CLIL network and through speeches and exhibitions that will allow us to share the experience with teachers from other schools.We believe that this project will allow us to consolidate our school as a multilingualism reference, to incorporate new methodological tools to our lessons, to improve our teachers’ linguistic and professional skills, to develop the quality and projection of our European projects and to implement more versatile management methods. On the other hand, this project is expected to improve the education quality which will have a translation in the academic results of our pupils, with positive effects on their learning process, widening their knowledge about the European Union and about languages spoken in it. In the long term, the benefits could be a better training and a bigger satisfaction of the whole educative community thanks to the introduction of innovative methodologies and to the advantage of learning in highly meaningful contexts thanks to the multidisciplinary European projects.The whole project in all of its levels will be constantly assessed to measure the achievement of the main objectives and the results of the project’s implementation and will end up with a final Report signed by the school’s Head Master. The assessment will be done by a variety of educative bodies: the project’s team itself; the Pedagogical Departments; the Curricular Board, the School Board and the school’s Management Board using a wide range of indicators both quantitative and qualitative as the objective improvement of the academic results in English and CLIL subjects or the degree of satisfaction of pupils and teachers regarding the CLIL lessons and the new methodologies.
