Envisage participated in 17th Panhellenic Conference of Greek Union of Physicists, with the two hours Workshop: “Design your own Virtual Laboratory”. The event took place in Thessaloniki (Greece), on Saturday 17th of March 2018. More than 20 teachers of secondary and higher education had the opportunity to play and test the games of Chemistry Lab and Wind Energy Lab. Moreover, their active presence and collaborative mood resulted in the design of a single educational game, using ENVISAGE’s authoring tool. Finally, the educators contributed to ENVISAGE with their evaluation, offering a useful feedback with suggestions and improvements for our project.
