The EduCardia SEL Activities handbook is going to contain description of the set of SEL activities with proper pointers to the available material per activity (e.g., textual resources, audiovisual material, images, web resources). All the collected material will be made available and served through a digital repository. The EduCardia SEL activities will be based on the EmoSocio model facilitating the training of all the specified emotional competences at individual and group level. The activities will be designed to be applicable in online or in-person classrooms. All the SEL activities will be made available in an open-access repository and will be searchable based on various criteria such as language, age, competences that tackle etc. The objective is to provide to the educational community an open-access repository with scientifically-valid SEL activities that can be adopted by any interested party within schools and educational communities.
