Effects on Training of Experimental Film Variables Study II. Verbalization, "How-It-Works," Nomenclature, Audience Participation, and Succinct Treatment. Rapid Mass Learning. Technical Report.
A study was conducted to ascertain which characteristics of instructional films affect learning. Fourteen versions of a film designed to teach the assembly of part of an anti-aircraft gun were prepared and shown to different groups of trainees. The study examined the following factors: 1) number of words of narration used to describe the action, 2) inclusion of a sequence explaining how the gun worked, 3) audience participation, in which trainees tried to assemble the gun at the same time the procedure was shown on screen, and 4) succinct treatment (the use of a concise but complete film presentation taken from an existing training film). The results showed that about 100 words per minute of film produced the most effective learning. Too few or too many words impeded instruction. The sequence explaining how the gun worked did not improve performance in assembling it. Audience participation worked if the film went slowly enough to allow trainees to watch it and do the task too. Succinct treatment was ineffective. Simply using the technical names of parts in the film did not teach those names to the trainees. (Author/JK)
