Technical Training: Development of Instructional Treatment Alternatives

The purpose of this report is to provide guidance in the development and evaluation of alternative instructional approaches that hold promise of improving instructional effectiveness. The main focus of the report is on how to identify and test interactive relationships between individual differences among learners and instructional conditions or treatments. The report directs considerable attention to problems of measurement that are basic to diagnosis and evaluation. The report rests on the conviction that there is no acceptable substitute for careful empirical experimentation; an approach must be tried, often several times, before evidence sufficient for credible evaluation is available. Underlying this conviction is commitment to principles of measurement. Identifying and defining learner aptitudes require dependable measurement. Detecting and quantifying the effects of instruction requires dependable measurement. (Author).
