This guide, itself composed of four modules, describes the preparation and use of modular materials for training programs in educational planning, educational administration and management, and educational facilities design. An initial module sets the context by considering the planning of an overall training program into which use of an individual module can be fitted. The major module in the series, module II, then focuses on the development of skills in writing modular, self-instructional training materials, and involves users in the preparation of a specific training module in their own subject areas. Using and adapting existing training materials into modular form is discussed in module III, which requires users to evaluate and adapt materials in their own subject areas. The final module explains the preparation of user guides for instructors and trainees. (LMM)
