This study was designed to discover whether a student learns to imitate the skills demonstrated in a motion picture more accurately when the supportive descriptive terminology is presented in an auditory (spoken) form or in a visual (captions) form. A six-minute color 16mm film was produced--"Determining the Test Weight per Bushel of Yellow Corn". One mode of the film used captions and the other mode used verbal comments. The test population consisted of 87 males enrolled in an agriculture course at Michigan State University. After examining the test data, the dependent variable data, and the independent variable data, the study concluded that visual supportive descriptive material was more effective than auditory descriptive material for identification of the parts of the apparatus, but both were equally effective forms in teaching students to imitate perceptual motor skills demonstrated by motion pictures. A bibliography and sample of the measuring instrument are appended. (JY)
