Investigation of several techniques for reviewing audio-tutorial instruction

Should students receiving a review of previously learned material show better retention than nonreview students? Do students using audio-tutorial review retain more than students using only a study guide? Students at Highland Park Community College participated in a learning-retention experiment. Subjects were assigned randomly to one of four review groups: study guide only, summary audiotape; compressed-speech audiotape, and no review. Analysis of retention scores incorporated Bartlett’s statistic, ANOVAs, and Dunnett’st. A CTMM IQ test also was given the subjects.
