This project is part of the erasmus+-project "Shifting boundaries", starting in autumn 2020 with the participating schools 12 Gymnasium of Peristeri, Liceo Classico Francesco de Sanctis, Ismail Sefa Ozler Ortaokulu and friedrich-List-Gymnasium Reutlingen. Central topics of the project in all phases will be “groups” and “boundaries”. We will especially explore the the cultural and social setup that a pupil grows up in. The participating student will be made to understand that society consists of numerous groups and that every of these groups defines a a catalogue of behavioral rules to be respected by its members. We want to use this platform as working platform.
