The subject of the paper is andragogy. In social work education (as in all education), complex issues emerge regarding the nature of learning and teaching. One pervasive and persisting issue is the relation between subject matter, i.e., what is to be taught, and teaching methodology, i.e., how it is to be taught. The paper discusses and illustrates interactive teaching principles, methods, and skills such as creating a climate and providing structure for collaborative learning, dealing with obstacles to collaborative learning, and helping students to experience, operationalize, and build abstractions.
