Discusses hypermedia; examines cognitive theories of learning and hypermedia; and describes hypermedia applications in science education, including physical delivery of information, curriculum design, and promotion of scientific inquiry. Research projects at Vanderbilt University dealing with aspects of science education, including elementary…

Discusses research issues related to using cognitive learning and instructional theory to design technology-based learning environments such as hypertext and hypermedia. A "Theory-to-Design" framework is described, and the framework is then used to analyze theoretical and design issues raised in a hypermedia research project. (Contains…

This study found that students using hypertext to learn technical information experienced an increased sense of control, and results provide preliminary evidence of an increased level of intrinsic motivation to learn among hypertext users. Implications for further research regarding the effects of hypermedia on intrinsic motivation are discussed.…
