This guide is addressed to teachers who develop information retrieval skills in users of scientific and technical information--undergraduate and graduate students, scientists, and technologists. It is intended to have particular application in developing countries. The teacher is likely to need expertise in library and information science, acquaintance with subject areas, teaching skills, and knowledge of local circumstances. Sections of the guide cover: (1) educational and instructional objectives and motivation; (2) arrangements to plan a course--promotion, teaching staff, and location; (3) preparation of courses with detailed objectives, variations in approaches, teaching and learning aids, case studies, evaluation, feedback, and self-instruction; (4) course content--topics and modifications; (5) methodology; (6) development of search techniques; (7) practical exercises; and (8) considerations such as student and subject differences and nonscientific subjects. The appendices include introductory tours of the library, handouts, examples of lectures and exercise sheets, and a list of further reading. (KP)
