The resources consists of 4 modules: One on approaches to supervision, one on collaboration in PBL (internally in the group and externally with other collaborators), one on management of conflicts in the group and one on the PBL life cycle from planning to exams. Each module is addressed to you as the supervisor, occasionally pointing out resources for the students to use. They are not structured in the same way, but generally we have strived to give short descriptions – in writings, in drawings, audios, videos and links to introduce the core concepts. An important guiding rule has been to offer specific, on the spot useful tools whatever the subject. Some of the modules offer exercises for you to complete. All of the modules offer references for further studies.
