An Investigation of the Effectiveness of Training Devices With Varying Degrees of Fidelity.
Grunwald, Walter
A study was made of the relative effectiveness of five selected training devices with varying degrees of fidelity in the learning of a psychomotor task in which manipulative skill was not vital. The hypothesis was this: an increase in fidelity may not produce a corresponding increase in effectiveness, whereas such factors as ability to engage a learner in meaningful physical and mental interaction may be more important than mere resemblance to the real equipment. Five homogeneous groups of Air Force students were randomly assigned to training with either the actual equipment, a functional simulator device, a partly functional mock-up, a full-sized photograph, and a small illustration of the equipment. All groups received identical instruction through a programed text and a tape recording. Training devices were evaluated on transfer of training as expressed by scores on written and performance tests. Results significantly favored the partly functional mock-up and suggested that the effectiveness of training devices may decrease when fidelity is increased beyond a certain optimum value. A model of this relationship was developed. (author/ly)
