Effects of Movement and Commentary on Manipulative Performance.
St. John, David Richard
The purpose of this four-group controlled experiment was to ascertain: (1) the effect of a motion model on a learner's performance behavior and (2) the effect of verbal description of the processes included in the demonstration upon a learner's performance behavior. After viewing video tape presentations, one with commentary and one without, of the tasks to be performed, 48 seventh grade girls were asked to cut and fasten two boards with a nail and to fasten two boards with a woodscrew, during which time a task analysis was used to identify hand and tool movements involved in the performance of the tasks. Rating scales were developed to measure the extent to which the subjects performed each of the tasks like the models which they had seen. A major conclusion of the study is that when a verbal description of the processes accompanies the visual demonstration of a manipulative task, the learners perform (imitate) significantly more like the model.
