Based on a state-of-the-art analysis of Army training, this report was the initial step in an effort to systematically improve the training in the combat arms and ultimately the entire Army. This study found that a comprehensive set of procedures was needed to provide for the development of effective training and for assessment of the training's effectiveness. In response to Task V contract requirements, an instructional systems development (ISD) model was formulated. The model contains five phases: analyze, design, develop, implement, and control. The initial step was to verify the content validity of the material and then conduct extensive formative evaluation. Performance and attitudinal data gathered during field trials of the material were used to determine where revisions were necessary in the final product. The completed package of validated materials, "The Interservice Procedures for Instructional Systems Development," includes a five-volume set of manuals (available in ERIC as ED 122 018-022) covering all phases of the procedures and a series of workshops for technical and management level personnel involved in the use of ISD.
