The training analyst must be able to specify training media requirements during the early stages of weapon systems development. Also, training specialists frequently need to make training media selections for center or base level courses. This report provides such personnel with information to assist them in the development of training equipment requirements. The selected annotated bibliography contains 200 references to government sponsored training media research and development reports from 1950 to 1966. All of these reports are available through the Defense Documentation Center (DDC) to military agencies and their registered contractors. Each reference bears a DDC Accession Document (AD) number. Research and development reports on various technical aspects of training media (except operator training) of a general nature are included. The report describes, classifies, and graphically presents representative training media. The bibliography contains references to (1) training media requirements, (2) training aids, including graphics, motion pictures, television, and general training aids, (3) trainers, and (4) teaching machines.
