The General Impact of the Dwyer Materials on the Acquisition and Retention of Information about the Heart.
Roberts, Dennis M.
The effectiveness of the Dwyer heart materials in facilitating learning and retention of information related to the heart under normal research conditions was investigated. Previous studies have focused on the manipulation of stimulus dimensions and not the effectiveness of the materials themselves. Data from three previous studies were compared and analyzed: (1) Lamberski's examination of effects of color coding; (2) Jennings's study of cue elaborateness and step size; and (3) Parkhurst's examination of the material's self-pacing nature. Results showed a large difference in pretest and immediate posttest values, indicating that the Dwyer materials were not maximally effective. Groups showed substantial loss between immediate and delayed retention testing. Even at the delayed testing, however, performance was substantially better than at the pretests. Data across the three studies were quite similar. The initial gain and delayed retention demonstrate that the heart instructional booklets are effective, especially under the experimental conditions in which they have been used. Three tables for data comparison and four references are provided. (LMM)
