Brant, George; And Others – Journal of Educational Computing Research, 1991
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…

Gray, Susan H. – Journal of Computer-Based Instruction, 1988
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)
