Case studies come in several forms and can be used for different pedagogic and academic purposes. The authors examine the role of case study in development studies teaching, reviewing definitions and actual usages. The experience of Harvard in the 1920s and 1930s is considered since there are parallels between business studies then and development studies today. Three dimensions of case study (not always clarified in the literature) relevant for development studies are considered: case study as a teaching method, particularly for small groups; case study as research activity; and case study and the process of generalisation in an interdisciplinary study area. The general argument is that there are good reasons for using case study, but for successful transcultural teaching, more attention needs to be given to educational issues where case study is used with students from a variety of different economic and cultural backgrounds.
