The educational commons concept relies on the idea of sharing space for collaboration, content creation, socialisation, governance, playing, and studying. The EU-funded SMOOTH project will focus on active social inclusion and examine if the educational commons can operate as a catalyst to inverse inequalities in education. The project proposes an innovative action research programme engaging children and youth to reverse inequalities that children and youth of vulnerable social groups face. It will reinforce intercultural and intergenerational dialogue and social integration, develop essential social and personal skills for both children, youth, and adults, establish spaces of democratic citizenship, and build and support the community through differences. SMOOTH will also perform a cross-cutting and cross-disciplinary analysis of educational commons.
