The Instructional Strategy Diagnostic Profile ISDP, an instrument for diagnosing defects in instruction and prescribing revisions, is designed to rate instruction on two major dimensions--consistency and adequacy. In this study, three experiments were conducted to test the hypotheses underlying the ISDPs consistency and adequacy prescriptions. Navy enlisted men were assigned to 12 treatment groups--four representing remember level instruction and eight, use level. Experiment I investigated the effects of manipulating consistency of test items and presentation strategies. Experiments II and III investigated the effect of manipulating adequacy of instructional materials designed to teach students to remember and use information respectively. Results provided strong support for the consistency prescription and for two of the three adequacy prescriptions for use level tasks. However, the two adequacy prescriptions for remember level tasks were not clearly supported. It was concluded that the ISDP is a valid instrument for predicting student performance and for evaluating instructional materials. Author
