LEARNING-STRATEGIES FOR UNSTRUCTURED HYPERMEDIA - A FRAMEWORK FOR THEORY, RESEARCH, AND PRACTICE

This article presents a review of major strategies for learning and in formation retrieval useful for learners, respectively users in coping with typical problems in unstructured hypermedia. They are derived fro m a process analysis of learning and information retrieval in ''hyperm edia-systems'' and related problems, and they represent a framework fo r collecting and integrating several approaches widely scattered and i solated from each other in the literature. Three global types of strat egies concerning goal attainment, spatial orientation, and knowledge a cquisition are distinguished and specified with several sub-strategies . For each sub-strategy its contribution to solve particular problems is discussed. The article closes with a discussion of theoretical and methodological shortcomings, respectively, open questions concerning r esearch and practical applications.
