This micro-module is based on the idea of developing solutions for the European Diploma and Flexible Learning Pathways in an international environment during the summer school hosted in Poland. Paricipants, ECIU teachers, will carry out in-depth teamwork in one of those topics. They will learn how to identify the challenge, obtain, and compile reaserch information and communicate the results in English on minimum CEFR B2+ level. The participants will be able to gain valuable creative problem-solving skills. This challenge is a chance to make a tangible difference in how we approach lifelong learning within the ECIU capacity. We invite teachers who are ready to create a meaningful change by benefiting not only themselves through skill acquisition, but also by making a valuable impact on the ECIU community.
