While interactivity is regarded as a distinguishing characteristic of computer technology, the explanation on its impact remains in its infancy. The present research investigates what it means to provide a more (or less) interactive computer interface design by attempting to uncover its cognitive influences on the user's expectation of outcome and…

Arguing that sufficient theory exists about the interplay between human information processing, computer systems, and the demands of various tasks to construct useful theories of human-computer interaction, this study presents a structural model of human-computer interaction and reports the results of various statistical analyses of this model.…

Reviews traditional functions of interaction in computer-based instruction (CBI); describes quantitative and qualitative perspectives on interaction strategies; discusses design-centered and learner-centered interaction; and presents methods for promoting cognitive engagement via mathemagenic and generative interaction strategies, including…

Discussion of research on computer-aided instruction (CAI) focuses on a set of questions and hypotheses that form the basis for research on the effectiveness of CAI. Four factors are highlighted: (1) the medium (including interactive videodisc); (2) the environment; (3) student characteristics; and (4) topic of instruction. (38 references) (LRW)
