Open sesame ! Sharing Enthusiasm, Stories and Actions in Millenials’ Europe puts active citizenship and learning at the center. The idea is to make teenagers switch from « user mode » into « actor's mode ». In order to challenge our students to share the leadership and get involved, the core idea of the project is to establish a set of CLUBS on different topics and interests to engage students into active participation and help them become responsible citizens of Europe. The main clubs will be focused on different fields of interest: Science, Debate, Art & Music, Geocaching, No Hate Speech, The Flipped Week, and a Summer Camp. Students aged 14-18, from 5 partner schools (Italy, France, Spain, Germany and Latvia) will travel to volunteer as language experts. We have created an Erasmus+ project in order to achieve our objectives, and the TwinSpace will be the tool used to support common work and exchange of ideas and materials.
