In a previous episode I talked about the kinds of dynamics that can occur in groups (social loafing, diffusion of responsibility) that can make them ineffective learning experiences as well as just not fun. In this episode I interview Dr. Karen Christian who has watched how many study groups in action and she has uncovered quite a few things that study groups need to do differently so that everybody actually learns and gets ready for an upcoming test. She's got some very useful suggestions for teachers and students.
