Relationship of Length and Fact Frequency to Effectiveness of Instructional Motion Pictures.
Vincent, W. S.; And Others
Significant learning occurred when four experimental films dealing with the weather were shown four groups in each of three different populations (high school students, Air Force basic trainees, and college students). However, increased concentration of facts in the films yielded only slight advantages in learning. The films differed in length as well as in factual content: the Long Heavy version ran 29 minutes and contained 224 facts; the Long Light version also ran 29 minutes but contained only 112 facts; the Short Heavy version ran 14 minutes and contained 112 facts; the Short Light version ran 14 minutes and contained 56 facts. All groups (those who saw the film and control groups who did not) took the same 136 item multiple-choice question information test. For the high school sample the Short Heavy version seemed to be the most effective; for the Air Force and college samples the Long Light version seemed to be most effective. At the end of the delayed recall period all differences in learning attributable to the several versions were much smaller than they had been on the immediate retention test, and most of them were not signficant. In no case did the Long Heavy film group learn twice as much as the Short Heavy or Long Light groups, nor did the latter learn twice as much as the Short Light group. (Author/MF)
