This document discusses case-based learning and education. It defines a case as a detailed instructional incident or narrative problem for which students seek solutions. The case-based method is used in teacher education to help students learn and apply principles flexibly in different situations. Students analyze cases in small groups to build knowledge and examine problems collaboratively. Effective case development draws readers in, builds tension, and ends on a dilemma. Assessment in case-based learning can be done fairly through standards like intellectual development, generative activities, and analytical activities. Case studies are also used in other fields like law, medicine, and business.
