The objective of the transnational project PROLEA is to develop, test, adapt and implement innovative practices in teacher professional learning based on a wide knowledge and experience of different European partners to face common challenges in teacher education in Europe. The project support the achievement of the European objectives formulated in the strategic framework for European cooperation in education and training 2020 (ET 2020). The PROLEA project has a systemic approach. The conceptual framework is based upon a series of consecutive projects, which reflect the history of in-service education and professional development. The project will concentrate on the main themes that lead to an inclusive school development (Facilitating professional development, School context, Content of professional development, Evaluation and reflection), and will use the knowledge and the experiences of all partners about instruments to strengthen reflection (portfolio/e-portfolio, video analysis, stories narratives). Project activities are based upon the following learning activities: - Learning from each other (peer-learning) with interdisciplinary teams, - Exchange of experiences with target-orientated issues (portfolio work), - Blended learning (in-person and virtual). This leads to 4 products that will be created within the project: 1. Common professional development modules which combine the themes of school development with instruments to a new approach of professional learning in complex settings, 2. Individual professional development modules from 6 partners to face the wide range of challenges in the different partner countries and to give others the opportunity to adapt and use the modules in their work, 3. Portfolio work of facilitators from the participating partner organisations, 4. A narrative learning report of the inter-organisational development to enhance professional development and development as learning organisations. The products will be produced in the languages of the project, and will be made available freely in a downloadable format from the internet (OER). The transnational work will have positive impact at different levels. There will be a high learning impact for the participating organisations due to a wide range of experiences within an international partnership. In total we will carry out 6 joint staff training events with 36 mobilities. It will raise the profile of the participating organisations and create new opportunities to extend the project and its results or develop new partnerships for the future. Sharing of the results will enable other stakeholder to benefit. The project results will serve as examples and inspire others by showing what is possible in European cooperation. By an effective dissemination and exploitation of the results on regional, national and international level there will be a raise of awareness, the engagement of more relevant stakeholders and a share of the developed solutions and know how. In the final phase of the PROLEA project, 4 final events will occur in Tilburg, Ljubljana, Aberdeen and Berlin, all with national and international participants. The goal is to maintain the communication of the results without interruption at the end of the project and thus give suggestions to imitate and to work for the strengthening of the professional development of education and training paths of educators. During the three year project there will be more than 500 participants involved from different European countries. The main target group of PROLEA are teacher trainers/educators and facilitators for school development, such as like counsellors, school coaches, school leaders, staff at school administration level and others who support schools in local education authorities. These people have an important role and direct influence in the continuing professional development of teachers. The second target group which we address are leaders who have a key role and/or are responsible for the organisation development of teacher education institutions. In the project consortium 7 different institutions of teacher education from UK, Netherlands, Germany and Slovenia are working together. They operate on different stages of teacher education from first phase till in-service teacher trainings. Applicant organization is the Senate Administration for Education, Youth and Science of Berlin (Germany), department for school administration in the district of Berlin Friedrichshain-Kreuzberg (Schulaufsicht). All partners act equally in the project implementation. The project members belong to a group under the umbrella of the Association for Teacher Education in Europe (ATEE). ATEE is a non-profit European organisation, whose aim is enhancing the quality of education in Europe and supporting the professional development of teachers and teacher educators at all levels. The deep integration of the partners to ATEE will support the sustainability of the project.
