Abstract

This experiment examined the effects of content domain expertise on the ability to identify goal-related units on a hypertext content map. Novice learners based their unit selections on similarities between the wording of the unit titles and learning goals (i.e., short-answer questions). Wording similarities had significantly less effect on the selections of experts. Experts' and novices' confidence ratings indicated that both groups were able to predict accurately the probable correctness of their selections. These results show that novices studying hypertext may select information on the basis of superficial text features, while experts can use prior knowledge to identify goal-related units. The fact that novices had less confidence in their incorrect selections suggests that they may readily correct these selections with further use of the content map.
