Exploratory Studies in the Effectiveness of Visual Illustrations.
Dwyer, Francis M., Jr.
Whether additional cues in visualized materials add to their instructional value is a question answered differently by various educational theorists. In the eight studies reviewed, experiments were designed to answer this question and other questions related to it. In three media studies using the same four treatments (oral presentation without visuals, with line drawings, with shaded drawings, and with color photographs), line drawings were most effective in the slide study oral presentation in the videotape study, and relaistic photographs in the programed instruction study. In another study, nine slide treatments having various types of visual illustrations were administered to 1054 high school students. Results indicated that at certain grade levels, color is an important instructional variable. Three later studies using a videotape of the nine slide presentations on 22-inch monitors, on a 5 by 3-foot front projection image, and on a 6 by 4-foot rear screen image found that students viewing the smaller images did better than those viewing images on the large screens. To summarize: where time is unlimited, simple line drawings are preferable; where time is determined by the students, as in programed instruction, more detailed presentations have greater learning value.
