The Project "Transformando nuestro centro con Europa" (Changing our school with Europe) arises from the real need defiined in our European Development Plan to become a successful school whose students achive the best possible results. This European project for mobility and cooperation is based upon the principles of sinergy and reciprocity. The main goal of the project is to improve the academic results of our students as well as our staff´s skills in order to increase significantly their competences through the new methodological experiences that they will definitely learn and absorb by the job shadowing activity in other European schools. The core activity of this project is doing a period of training through the observation of good teaching practices in many subjects, such as English, Spanish as a second laguage, maths and science. The partner schools to visit during this project have been thoroughly selected according to their excellent results in terms of education, which put them among the best in the ranking of their countries, and our good relationship and cooperation in previous European projects. The potential impact of this project on the participant teachers will be hugely positive, multiplier, permantent and sustanaible. It will overstep the school walls, reaching all the students, teachers, parents and other members of the school community. It will allow us to strengthen the bonds with the partner schools towards greater and better cooperation in future international projects, it will improve the general skills of our teaching staff, with a wider and reacher view of the teaching-learning process, with better and more accurate digital, linguistic, social and methodological competences and with a greater knowledge of new methods, all of which will give a direct contribution to changing our school. By the end of the project, the participant teachers will use the gained skill and competences to present some practical products, capable of being measured and disseminated: 1. "Manual of good European practices for changing schools". 2. E-twinning projects with different goal withing the scope of each subject: English, Maths, Spanish, Science,... 3. Creation of a work group in the Local Center for Teachers´ Development. 4. Teachers Portfolio, using the "project diary" tool in our twinspace platform on a daily basis. 5. Pilot project carried out in our school for a week, during which the participant teachers will deliver their classes in the same way they have watched and learnt when they were doing their job shadowing, so that students perceive the changes in their teacher´s methods of teaching and are able to appreciate the differences between the previous and the new methology. The dates for this experience have been established among the partner schools during the preparatory stage, looking for the best moments for each school and makng them coincide with the the beginning and ending dates of other European cooperation actions we are carrying out within the Erasmus + programme, such as long term mobility for students Our Dissemination Plan has been designed during the preparatory stage and contains two sets of actions to spread the results from this experience. It is based on two kinds of activities: Internal Dissemination (addressed to all members of school community) and External Dissemination (addressed to the general public at a local, regional, national and European level). Our evaluation plan has been designed during the preparatory stage and is composed of two parts: quality evaluation and quantity evaluation. It is based on the model of our "Follow-up and Measurement plan" that we have been carrying out in our school since 2004 by the Quality Management System. This system allows us to assess up to what extend different projects have successfully reached their aims based on objective indicators evaluated through questionaires and audits, both internal (made by the coordinator of school quality) and external (made by independent auditors experts on the education field).
