As part of the overall goal of the Environmental Protection Agency (EPA) to help provide environmental professionals with the skills required to plan and deliver training programs, this participant reference manual, and its related staff guide, have been developed for conducting a workshop in basic instructional technology. The workshop consists of 12 units totalling approximately 25-35 hours of classroom time if the entire course is presented. Each unit includes an overview, unit lessons (with the corresponding learning activities), and lists of objectives and resources needed for the lessons. The emphasis of the units is on the development of the basic, practical skills of: identifying instructional needs; specifying objectives; planning instruction; locating support materials; conducting instruction using various formats and effective speaking techniques; and evaluating the performance of those who receive the instruction. Most of the content is treated on a strictly applied basis with a minimum of theory and technical explanations. Instructional activities include lectures, guided discussions, demonstrations, individual assignments, and readings. Materials in appendices include references, a glossary, and a description of other United States EPA instructional support services and materials. (JN)
