Abstract:

The purpose of this research was to determine the effect on learning of varying 1 the total amount of factual information presented in a film of a given length, and 2 the length of time allotted to conveying a fixed amount of information. The question is Does increasing the concentration of facts in a film result in a proportionate increase in learning. Four experimental films on aerology were shown. The Long Heavy version ran 20 minutes and contained 224 facts the Long Light version also ran 29 minutes but contained 112 facts. The Short Heavy version ran 14 minutes and contained 112 facts the Short Light version ran 14 minutes but contained 56 facts. Results indicated that significant learning occurred. Every group which saw an experimental film earned a substantially higher score than the control group which did not see a film. The best version in an all-around sense on the basis of total score differed from population to population. 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.
