Many basic skills are chains of cognitive operations. For teaching such skills, two questions have not been adequately investigated: (1) how the operations comprising the skill should be sequenced, and (2) the relationships among the operations that need to be taught. This investigation entailed four studies on different types and lengths of basic…

Describes a study of undergraduates studying genetics that compared the effectiveness of a computer simulation used before and after formal instruction. Treatment of the experimental and control groups is explained, and results are reported which support the theory that the effectiveness of the simulation is dependent on the sequence of…

Discussion of control over sequence of instruction in computer-assisted instruction (CAI) focuses on a follow-up study that examined the effects of the breadth and depth of menus and the meaningfulness of menu category names on the learning and attitudes of college students. Posttests are described, and results are analyzed. (16 references) (LRW)

Discusses research on learner control, pacing, and sequence, and describes a study of undergraduates that was conducted to determine the effects of learner versus program control of pacing and sequence in an interactive video lesson on photography. Results are analyzed, and suggestions for further research are given. (38 references) (LRW)
