Abstract
AbstractThe purpose of this study was to test Gagne’s hypothesis that attention to prerequisites should be more effective than repeated practice of a final task when learning intellectual skills. Ninety eighth-grade general science students studied self-instructional materials on the construction and interpretation of graphs. After each of three lessons each subject took a diagnostic test covering the objectives of the instruction. Subjects in Group 1 received additional instruction on prerequisites as remediation. Subjects in Group 2 received additional practice items as remediation, and subjects in Group 3 received no remedial activity. Students receiving remedial instruction did significantly better than those receiving only main-line instruction. Students receiving additional instruction on prerequisites did significantly better than those receiving additional practice items as remediation.
