The overall objective of the 21st Century European Teacher project is to gain insight into how European teachers can approach and develop teaching in emerging subject areas (Technological empowerment, Sustainable learning, Entrepreneurship, Playful learning), that arise as a result of large complex upheavals affecting society e.g., climate changes and the ubiquitous digital development. The partners aim to join forces in a collaborative action to develop and innovatively improve the competencies and attractiveness of the teaching profession by establishing strong European partnerships between teacher education and training providers and providing sustainable teaching practices across borders through mobility activities in a blended approach to teaching and learning. To obtain this the 21st Century European Teachers project has 4 specific objectives: 1.Provide a beyond state-of-the-art mapping laying the ground for a common understanding of the four subjects and establishing a strong network of 30 pre- and in-service teachers as a driver for mobility during study visits and co-organized teaching events (five completed) across borders. 2.Design, develop and try out 21st Century joint learning modules for 200 pre- and in-service teachers in a “21st Century European Teacher co-education model” building on the mapping and establishment of the strong network. 3.Provide recommendations for the 21st Century European Teacher Curriculum around the four subject areas through five learning modules (MOOCs) made available via eTwinning. A minimum of 150 pre- and in-service teachers will be enrolled in one or more of the MOOCs across countries.4.Provide recommendations on the policy level by conducting five dialogue labs at national level with 30-50 participants from each country and an European workshop for a broad European network to inform relevant stakeholders. The 21st Century European Teacher Co-education Model will be the framework to accommodate the objectives.
