Evaluating Maintenance Performance: A Video Approach to Symbolic Testing of Electronics Maintenance Tasks. Final Report.

Abstract : The 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 development and tryout of such criterion referenced tests and promising graphic symbolic substitute tests are reported in previous volumes. 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. In addition, some dynamic displays would have been desirable for those graphic symbolics where as all of the original graphic pictorials are static. The anticipated results that the video media would provide satisfactory and economical solutions to these problems, did not materialize.
