Research on instructional development

The instructional technology field is periodically faced with discussion of the appropriate direction of its research and move specifically of the relationship between research and practice. This paper extends the discussion by examining the nature and scope of developmental research. Two categories of developmental research are explored. They vary in terms of the extent to which the conclusions resulting from the research are generalizable or contextually-specific. Type 1 research tends to be case studies of specific design, development, or evaluation projects with its findings directed toward the improvement of a product or identification of those conditions conducive to efficient product development and use. Type 2 research typically addresses the validity and/or effectiveness of an existing or newly constructed development model, process, or technique. The promise of developmental research as a vehicle for creating sound methods for linking research and practice is discussed.
