Huelin is a secondary school in the city of Malaga. The staff is composed of 65 teachers, attending to a population of more than 950 students from over 28 nationalities, with a foreign student rate of 16,42 %. There is a group of teachers in our school very committed to international partnership. We finished a two-year Comenius partnership last year with great success. Some of us took over the coordination of a new partnership from our coordinating English school to apply for an Erasmus+ strategic partnership. The three main topics of this project emerged after we analysed the current socio-economic situation and assessed the needs at our school: 1) Entrepreneurial spirit and business culture to foster self-employment. 2) Energy awareness on topics such as energy efficiency, use of renewable energy, CO2 emissions and waste management. 3) Improvement of the teaching learning process on a variety of aspects such as student diversity, inclusion of SEN students, the school library, absenteeism, Open Educational Resources ( OER), innovative and motivating teaching methods, as Project or Problem-based learning. Our main project objectives are: a) To increase knowledge and raise ecological awareness in sustainable and renewable energy, waste and environmental management, energy efficiency, CO2 emission reductions. To increase the number of actions and facilities we can implement in order to save in costs both at school and at home and not to damage the planet. b) To improve the teaching-learning process through innovative and motivating teaching methods and good practices, such as project or problem-based approaches and open educational resources, especially in Mathematics, Science and Languages. To develop initiatives on the teacher and student level, especially where the most deprived students are concerned. c) To foster the entrepreneurial mindset, as well as the skills and employability of our students, giving them help in order to start, run or grow a business or enterprise. There are 6 secondary schools, most of them with a CLIL approach: “ Penair School” in England is a specialist school for Science, “Liceo Classico Vittorio Emanuele II” in Italy is specialized in History of Art and Languages, “Tampereen Lyseon Lukio” in Finland and “Cato Bontjes van Beek Gymnasium” in Germany focus on Natural and Social Sciences and Languages, “Gimnazjum nr 1 im. Jana Pawla II” in Poland has a Sport and Language profile, and finally our school mainly focuses on the areas of Mathematics, Languages and ICT. Every school has their strengths and weaknesses, but we believe that every school community will gain in the following aspects after the completion of this project: STUDENTS: collaborative working, self-learning and e-learning (OER); motivation for learning, especially the most disadvantaged students; business spirit and the entrepreneurial capability to start a business or an enterprise; ecological and energy efficiency awareness; European identity; English language; emotional, cultural, autonomy and personal competences (e.g. by living together in the mobilities),… STAFF: professional and pedagogical development in relation to e-learning ( OER), project and problem-based teaching approaches, Work-related Learning, Home Economics, CLIL methodology, entrepreneurial culture, international collaboration beyond the life of the project, ecological learning activities,… SCHOOL: international dimension, effective teaching methods, eco-school team, commission for partnerships, school project and programs permeated with an entrepreneurial and ecological spirit ( e.g. by the entrepreneurship corner or school garden), energy and water saving( e.g. by green facilities),… FAMILY: acquire an enhanced sense of European cohesion by hosting foreign students, active participation in the school activities (e.g. by helping with the energy and waste management activities),… Through our dissemination plan we expect our experience to reach other schools and institutions, encouraging them to collaborate in the future. Our dissemination plan goes from a local or regional level in newspapers, television channels, associations, town halls, local educational authority platforms,… to a national and European level in platforms such as the Spanish Ministry of Education and the European Commission. In addition, every country will design their own dissemination plan. We will have activities before (coordination and preparation), during (collaborative working, brainstorming, brainwriting, making materials, sharing and exchanging information, job shadowing, visits, evaluation) and after the mobilities (presentations, monitoring, putting into practice some ideas, dissemination). Finally, we have to say that one of the motives that encouraged us to start this project was its sustainability, in terms of maintaining the results of the project and continual improvement (e.g. school entrepreneurship contest, green facilities, lists of OER).
