Heal the earth- training course was implemented at the Mühl-fun-viertel in Klaffer am Hochficht, Austria between the 07.05. – 14.05.2023.

Promote new youth network initiatives based on NFE methods as tools for social transformation 5. Create space for the exchange of experiences / project ideas. We considered that all original objectives of the project were reached in 100% during the project, by all our activities that we realized. We considered that we achieved more than these objectives, by increasing the collaboration and communication in the group, that started to work as a team from the beginning, crossing all the linguistic, cultural and age barriers. Achieving the goals was the most important aspect that we had pursued. To that end, we considered it important to create and maintain a secure work environment and optimal group dynamics. We chose relevant knowledge activities between participants and teambuilding activities. We used the "secret friend" game, where participants received positive feedback, encouragements, appreciations on the tickets that were gathered in the envelopes made by each. We had ensured that every evening we had interesting activities where participants were motivated to participate: intercultural evenings, board game evening, dance evenings, camp fire, etc. All these had made a significant contribution to achieving the project goals.
