This document discusses the case study method of teaching. It defines a case study as an intensive investigation of a particular real-life or fictional situation. It outlines the steps to teaching with case studies, which include clarifying objectives, preparing, organizing discussion in small teams with clear goals and roles, discussing the case by exploring relevant angles and analyzing the problem. It also discusses writing case studies using a backwards design that presents an open-ended problem without a single right answer. The document notes the merits of developing scientific thinking and applying theory to real situations, as well as the potential demerits of not being able to cover all material and giving students an inflated sense of importance.
