Content Treatment Interactions: A Better Design Model.
Jonassen, David H.
Conceptual and methodological problems inherent in Aptitude Treatment Interaction (ATI) research, coupled with the impracticality of its application, call into question its use as a design model. For these reasons, ATI should be de-emphasized as an instructional design model and attention should be refocused on the structure of content and the differences in the information processing required to assimilate it, rather than on learner characteristics. These changes would affect the design field by replacing traditional behavioral task analysis with content analysis. Designers would seek to accommodate differences in the content, not in learners. The dividends from research would be more readily applicable to material design and would probably produce greater overall effects. This paper does not intend to refute the existence and importance of individual differences, merely to stimulate dialogue about their implications for instructional design vis-a-vis the nature of subject matter content and its information characteristics. The ideas presented in this paper are intended only to instigate discussion; they are not intended as preclusive answers. Too often that mistake has led us up the blind alley of advocacy. Seventy-six references are listed. (Author/LLS)
