Desi facilitates interaction between students from different countries, in a low-key approach and with a focus on relevant topics as culture, lifestyle, food, traditions, history, music, etc. During this interaction students use English as a means of communication, through social media and whatever helps them to be in contact. Four schools recruit a similar number of students. (10 for the pilot). These four schools are in Spain, Slovakia, Denmark and the Netherlands. Students are teamed up in teams of four, with one member from each school.
