The Third World countries of Botswana and Tanzania have used Radio Learning Group (RLG) campaigns effectively to get a limited amount of important information to a very large group of people at the same time. During campaigns voluntary participants organized in groups of 5-20 meet twice a week for about 5 weeks to listen to radio broadcasts about topics of national importance and to study supporting printed materials with the aid of a group leader. The group feeds questions and comments back to the government. Intended for organizers, teachers, administrators, and students of adult education, the manual explains in detail the 10 steps of organizing a campaign; the development of materials coordinated to the radio broadcasts; the field work essential to a successful RLG campaign; the training necessary for personnel at the national, district and town, village and ward, and group leader levels; and the evaluation of the campaign. Short sections provide suggestions for starting with experiments and pilot programs, following up with action, and consulting about the projects. Appendices include examples and flow charts from RLG campaigns in Botswana and a brief bibliography. Small black and white cartoon characters guide the reader through the manual. (SB).
