A Survey of Extant Development and Evaluation Models Used in Regional Educational Laboratories and Research and Development Centers.

Results are presented of a survey designed to elicit information from labs and centers on the types of development models that are currently being used in product development efforts and the evaluation strategies or models that have been found to be most compatible with them. The case is made that a great deal of research needs to be conducted on evaluation and development procedures before empirically based policy can be developed. Before such a research base could be provided, two significant conceptual problems have to be addressed. First, how does one define, identify, and describe development and evaluation models per se, and secondly, how does one determine when an instructional technology perspective is indeed more relevant than an industrial management or value research perspective?
