Comparative Effects of Ability and Presentation Mode in Computer-Assisted Instruction and Programmed Instruction.
Dick, Walter; Latta, Raymond
A comparison was made of a programed instruction (PI) text, which had been developed following a systems model, with a comparable computer-assisted instruction (CAI) version of the same material. The text was designed to teach the mathematical concept of significant figures to eighth graders. The PI text consisted of 52 linear frames. The CAI program, which was presented on a cathode-ray tube terminal (CRT), had the same basic frames plus remediations for incorrect responses as well as remedial loops. An analysis of immediate posttest scores, retention scores, number of errors in the learning program, and learning time indicated that: (1) high ability students performed better than low ability students; (2) students using PI performed significantly better than those using CAI; and (3) in all cases there was a trait-by-treatment interaction. The observed differences were attributed to the very poor performance of the low ability students who used the CRT terminal. It is suggested that low ability students may require hard copy memory aids to supplement CAI learning experiences. (Author/JY)
