Evaluating Maintenance Performance: A Video Approach to Symbolic Testing of Electronics Maintenance Tasks. Final Report.
Shriver, Edgar L.; And Others
This volume reports an effort to use the video media as an approach for the preparation of a battery of symbolic tests that would be empirically valid substitutes for criterion referenced Job Task Performance Tests. The graphic symbolic tests require the storage of a large amount of pictorial information which must be searched rapidly for display. At the time this video effort was started, no completely satisfactory way had been found for rapidly searching and displaying such information. The anticipated results that the video media would provide satisfactory and economical solutions to these problems did not materialize. From a testing point of view, video symbolic tests place the test subject in a passive evaluative role of watching someone else perform each task. Success in this passive role does not ensure his success in the active role of performing the same task. Also, the development costs of the video tests proved to be very high in terms of video equipment and test development time. To obtain video materials of acceptable quality, would require both quality video equipment and studio production facilities. As a result, it was recommended that video should not be further considered as a testing medium for performance analogues and that future efforts should be aimed at improving and refining graphic symbolic substitute tests.
