Performance support and usability: An experimental study of electronic performance support interfaces by Rawls, Charles L., Jr., Ed.D., University of Central Florida, 2005 , 120 pages; AAT 3193500 My Interest: 1) Checklist. 2) Online Questionnaire – PUTQ. 3) Online Questionnaire – UCFUQ. Action: To read the Dissertation in the future. Research Goal This study evaluated the usability of two types of performance-support interfaces that were designed using informational and experiential approaches. The experiment sought to determine whether there is a relationship between usability and the informational and experiential approaches. Methodology Two instruments---a checklist and an online usability questionnaire-- -were used to measure the five dependent variables: efficiency, intuitiveness, errors, satisfaction, and student performance. First, a checklist was used to assess the students' performance completing their task, which was a copyright issue request letter. The checklist was designed as a performance criterion tool for the researcher, instructor, and participants to use. Second, an online usability questionnaire was constructed based on the Purdue Usability Testing Questionnaire (PUTQ) questions to measure interface efficiency, intuitiveness, errors, and satisfaction. This study tested two approaches to user interface design for the Electronic Performance Support (EPS) using two HTML interface templates and the information from an existing training module. There were two interventions consisting of two interface types: informational and experiential. Results Discussion Results of this study indicated that students at the University of Central Florida reported no differences between the two interface types. It was postulated that the informational interface would yield a higher mean score because of its implementation of HCI guidelines, conventions, and standards. However, it was concluded that the informational interface may not be a more usable interface. Users may be as inclined to use the experiential interface as the informational interface.
