Complex and authentic – or “Rich” – cases are an integral component of Team Based Learning (TBL), particularly in the health-related professions. We have developed an approach to aid in the development of complex cases suitable for use as application exercises in TBL. This workshop will focus on how to develop cases to meet specific learning objectives. Using templates created from collaborative learning and case-based learning literature, participants will build a case in steps. A collaborative approach will be used during the workshop, allowing participants to learn from each other as build and share their work.
