Knowledge Puzzle: A Tool for Constructivist Learning from Hypertext

This paper presents Knowledge Puzzle, a tool for knowledge construction from the Web. Its main contribution to Web-based learning is the adaptation of information structure on the Web to cope with the interlinked knowledge structure in the learner's mind Self-directed learners will be able to adapt the path of instruction on the Web to their way of thinking, regardless of how the Web content is delivered The way to achieve that is to provide the learner with a meta-cognitive tool that enables him to bring his knowledge to the surface and visualize what he has in mind Once we get the learner's viewpoint externalized, it will be converted to a hypermedia layer that will be laid over the Web pages visited by the learner. The attached layer adapts the views of Web pages to the learners information needs by associating information pieces that are not already linked in hyperspace and attaching the learner's notes to the page content.
