This practice session is aimed to allow participants to discover and explore EMMA platform, both from the student and teacher/tutor perspective. After a presentation about structure and functioning the session will follow with a guided tour: participants will be invited to register to the platform and to enrol to one or more MOOCs. Furthermore it will be possible to access the platform with a teacher profile to create/modify contents, manage communication with students in order to get a better understanding of the underlying design principle of the EMMA platform. This presentation was given during the EMMA Summer School, that took place in Ischia (Italy) on 4-11 July 2015.
