This handbook is designed to help administrators, educators, politicans, and others engaged in distance education who seek to introduce, extend, or improve correspondence education for adults. In the first of six chapters, the background and history of correspondence study, particularly in Britain and the United States, are reviewed. Chapter 2 discusses international practices, definitions, clients, and sources of correspondence study. Correspondence study is defined as study based primarily on printed materials; it is considered a part of education at a distance. Six categories of organizations employing distance systems are identified. The third chapter provides a practical analysis of correspondence teaching and learning. Chapter 4 discusses the linkage of radio to correspondence courses in multi-media systems. Chapter 4 focuses on college planning and administration and presents a comprehensive model of a medium-sized correspondence unit or college. The final chapter presents an example of distance education in a case study on Thailand. Two appendixes include (1) an excerpt from an article on pedagogical aims, opportunities, and drawbacks in Thailand and (2) selected reference materials. (CSS)
