Field Evaluation of Enriched Hybrid Job Performance Aids.
Abstract
Twenty Navy technicians participated in a field evaluation of the effectiveness of enriched hybrid job performance aids (EHJPAs) for troubleshooting the AN/AWC-10 airborne weapon control system. In a between-subjects design, each group used one of four troubleshooting formats on two troubleshooting tasks: deductive information only (DED), hybrid aid without any enrichment (UN), an enriched hybrid (TS/IC), and another enriched hybrid with techincal data references (SS/BRC). Performance across tasks, as well as performance on a pre- and posttask using the DED format were compared. Using the TS/IC format, technicians solved the two tasks 58 percent faster than did the technicians using DED. Improvement from the pre- to posttasks for the TS/IC group was 65.6 percent, compared to 31.9 percent for the DED group. One hundred percent of all hybrid groups solved the posttask, compared to the 83 percent of the DED group. One hundred percent of all hybrid groups said the hybrid aids were easier to use and understand than existing technical material. In a test on system knowledge, the SS/BRC group was superior when compared to the other groups. Combining the results with the user preference for the SS/BRC format, it was concluded that the SS/BRC was the most effective EHJPA. (Author)
