Map-Based Horizontal Navigation in Educational Hypertext

This paper discusses the problem of horizontal (nonhierarchical) navigation in modern educational courseware. We will look at why horizontal links disappear, how to support horizontal navigation in modern hyper-courseware, and our earlier attempts to provide horizontal navigation in Webbased electronic textbooks. Here, we present map-based navigation -- a new approach to support horizontal navigation in open corpus educational courseware that we are currently investigating. We will describe the mechanism behind this approach, present a system KnowledgeSea that implements this approach, and provide some results of a classroom study of this system. Categories and Subject Descriptors H.5.1 [Information Interfaces and Presentation]: Multimedia Information Systems - Hypertext navigation and maps. General Terms Documentation, Design, Human Factors.
