Margitta Holler, Head of the Department of Studies and Didactics at HAW Hamburg, visited our course and guided us in our collaborative processes. In a workshop on Topic-centred Interaction, we learned about exciting collaborative systems, and in the following weeks, we discussed our wishes and concerns about collaboration in groups. Later, Ms Holler came back to us and looked at our process and how the form of collaboration we had discussed at the beginning of the course may or may not have changed. She supported us in difficult group formation processes and encouraged and guided us in our communication in different situations.
