The Greek DoCENT co-design workshops (E6) took place between 16th of February and 16th of March in Athens. There were three training events organised at the 2nd Experimental Junior High-School of Athens, where 46 teacher educators were trained to use the DoCENT MOOC (O2) content and Serious Game (O3). In addition, 8 EdTech researchers and stakeholders participated in these events and facilitated the training together with the DoCENT team from Greece – Prof. Chronis Kynigos and Dimitris Diamantidis. The participants enjoyed playing with the Serious Game, study the MOOC content around STEM and design their own learning scenarios for pre-service and in-service teacher education. More than 50 scenarios and important evaluation of the educational material were the outcomes of the workshops.
