This paper examines prior research on learner control in an effort to apply the findings to the design of interactive video systems. Early research on learner control is detailed, including descriptions of research supporting learner control or having mixed reactions to learner control. Alternatives to learner control are also discussed, including adaptive control strategies and learner control with advisement. The effects of learner characteristics on learner control are then considered, and research that specifically considers interactive video is detailed. Suggestions for the effective design of interactive video materials emphasize the importance of training, the need for individualized design, and the effect of content on learner control and retention.
