Designed to stimulate and support training for Extension work and to orient new employees, this book covers the Cooperative Extension Service (CES) and its methods of operation. It begins by describing the status of rural extension in the United States and abroad; the history of the CES and its antecendents; the legal basis, scope, functions, and general objectives of the CES; and its administrative organization. Some contributions of sociology and educational psychology are also set forth. Program development is discussed in terms of changing emphases and of the quest for fuller, more effective clientele involvement. Part 4 gives guidelines on radio and television, visual aids, ephemeral publications, demonstrations, meetings, Four H clubs, community development, rural development, lay leadership, group discussion, and other methods and techniques for planning and carrying out change. Subsequent chapters deal with reporting and public relations, personnel training and development, and prospects for the future. Appendixes include an index, and legislative provisions, followed by the Memorandum of Understanding between Louisiana State University and the Department of Agriculture. (LY)
