Impact of Navigational Models on Task Completion in Web-Based Information Systems.
Frick, Theodore; Kisling, Eric; Cai, Weijia; Yu, Byeong Min; Giles, Frank; Brown, J. P.
This study investigated performance differences between three different World Wide Web-based navigation models: linear, persistent, and semi-persistent menu structures. Subjects, 44 graduate and undergraduate students at Indiana University and public school teachers, were placed into one of the three navigation conditions and completed information-finding tasks. No significant differences were found among the models with respect to success in completing tasks or overall completion time. Use of other navigation aids built into the browser, such as the "home" and "back" buttons, was also measured, as well as user satisfaction and perceived usability. No differences among models were found here either. Results of this study tentatively indicate that the three navigation models, as tested, performed equally well and further that designers should give fair consideration to each of the models pending the purpose and audience of the site being designed. Further research is needed, since several potentially confounding factors were identified. (Author/MES)
