To contribute to a deeper understanding of distance education and its potential development, this 19-chapter book systematically relates correspondence education to seven teaching models: Skinner's behavior control model, Rothkopf's model for written instruction, Ausubel's advance organizer model, Egan's structural communication model, Bruner's discovery learning model, Rogers' model for facilitation of learning, and Gagne's general teaching model. Following two introductory chapters covering background, aim, and teaching models, each of the seven models is discussed in depth. Each model is first described, with an explanation of its view of learning and teaching. Then, specific ways in which the model could be applied to correspondence education are examined. A summary chapter discusses the possibility of applying the models to correspondence education, suggests factors to be considered when choosing and applying models, and describes possible functions of postal two-way communication. An 8-page reference list is included. (Author/LMM)
