STENCIL includes 21 members from 9 European countries, providing joint expertise to contribute to the improvement of science teaching, by promoting innovative methodologies and creative solutions that make science studies more attractive for students. STENCIL will offer to science teachers, schools, school leaders, policy makers and practitioners in science education from all over Europe, a platform to encourage joint reflection and European co-operation, offering high visibility to schools and institutions involved in Comenius and other European funded projects. STENCIL will carry out a survey aimed at identifying innovative science teaching methodologies and good practices at national and European level, taking advantage of the positive results achieved by the former European project STELLA - Science Teaching in a Lifelong Learning Approach - and namely the European Online Catalogue of Science Education Initiatives and the eBook "Science Education in European Schools - Selected Practices from the STELLA Catalogue", which will be updated and enriched with the contribution of all partners. The results of this work will be published every year in the "Annual Report on the State of Innovation in Science Education", and will be presented in the international conferences and the national dissemination events organised in the partner countries. STENCIL will offer to science education practitioners opportunities to share experiences and learn from each other by organising periodical study visits and workshops, in a peer to peer approach aimed at facilitating the transfer of good practices. Additionally, a set of Guidelines for innovating science education will be diffused among educational authorities and policy makers in the partners' countries. STENCIL will last 3 years and it will reach about 22.500 teachers though the web portal, 1200 participants through the dissemination events and 1500 authorities and schools through the Guidelines and Manifesto.
