An Experimental Study of the Use of Visual Illustrations Used to Complement Oral Instruction on Television.
Dwyer, Francis M., Jr.
Five slide sequences, each containing 39 black-and-white slides designed to complement oral instruction, and carrying a 32 minute oral instructional unit on the heart, were presented to 269 college students in five groups through a television receiver. The purpose was twofold: to determine if redundant information presented simultaneously through eye and ear results in more effective learning than if the information is presented through the ear alone, and to measure the relative effectiveness of varied types of visual illustrations used to facilitate student realization of varied educational objectives. The results of the tests indicated that visual aids are effective when learning objectives are similar to those measured by a drawing test, but that they are unnecessary and even distracting when the learning objectives are similar to those measured by terminology, identification, comprehension, and total criterion tests. This may be because college students have already been selected for their verbal and conceptual ability. In televising presentations, therefore, for college level instruction, visual materials should be used only insofar as they are justified by learning objectives and achievement. (GO)
