Evaluating navigation history comparison

Abstract

Self-directed navigation involving knowledge construction in learning Web contents, called navigational learning, is not so easy for learners since they often fail to notice the pages to be learned and semantic relationships between the pages navigated. It is accordingly necessary to enhance their awareness of the incompleteness of knowledge that they have constructed. We call such awareness unknown awareness. However, it is hard for learners to gain it by themselves. We have developed the system, which enables them to compare their navigation history to others, and which can select some navigation histories more appropriate for the history comparison from a repository. This paper describes a case study with the system whose purpose is to ascertain if the history comparison contributes to providing an unknown awareness. © Springer-Verlag Berlin Heidelberg 2005.
