This manual is a step-by-step, comprehensive guide for the training of development workers produced by the Peace Corps. It begins with introductory ideas and assumptions about development. Notes to the trainers on use of the manual are provided. Materials are then presented for six training sessions: introduction to development, the dynamics of development, information as a development tool (two sessions), working with others--the role of the development worker as helper and consultant, and problem solving--individual approaches. Each session is organized as follows: time, objectives, overview (summary statement of purpose and rationale and brief description of what will happen in the session), procedures (the training activities suggested to accomplish the goals and the approximate time to complete each activity), materials list, trainer notes (suggestions on how the procedures can be modified, tips on possible outcomes or problems, and suggestions for additional activities), and attachments and handouts (trainer reference or background material, resource articles, case studies, discussion questions, exercises, reading assignments, and inventories). The final four integrating sessions are intended for use as a 2-day development workshop. They cover community and job entry, project planning and goal setting, project management, and responsibility of development work. (YLB)
