This examination of the Air Force instructional development model begins by presenting the history of instructional development in the Air Force and providing reasons for the adoption of the instructional systems development (ISD) process. Each step of the ISD process is explained, and supporting forms and diagrams are provided. The steps considered include system requirement analysis; development of job performance requirements; development of objectives and tests; planning, development and validation of instruction, including selection of instructional methods, media, and materials; and evaluation. Steps and methods peculiar to the military or the Air Force are emphasized, and problems encountered by the Air Force in the implementation of this process are discussed. Four figures and three tables are included. (Author/EW)
