Adaptive Educational Hypermedia Systems (AEHS) play a crucial role in supporting adaptive learning and immensely outperform learner-control based systems. AEHS' page indexing and hyperspace rely mostly on navigation supports which provide the learners with a user-friendly interactive learning environment. Such AEHS features provide the systems…

Presents a framework for organizing research and theory in the areas of psychology, pedagogy, and technology as they relate to interactive multimedia; and derives principles and implications for the design of interactive multimedia. Highlights include prior knowledge, the organization and utilization of knowledge, feedback, concept maps, and…

Users of educational hypertext are faced with the challenge of creating meaning both within and between texts. Cohesion is an important factor contributing to whether a reader is able to capture meaning and comprehend text. When readers are required to fill in conceptual gaps in text, comprehension can fail if they do not have sufficient…

This quantitative study compared the instructional effects of two web-based animation strategies against static graphics by high and low prior knowledge participants. One strategy used animation to gain attention; the second to gain attention and provide elaboration. Participants were 111 college student volunteers. Two-way multiple analysis of…

Describes the design and evaluation of a multimedia course on integrated circuit manufacturing that was developed at the University of California at Berkeley using IC-HIP (Integrated Circuit-Hypermedia in PICASSO), a hypermedia-based instructional system. Learning effects based on prior knowledge, methods of navigation, and other factors are…

Empirical evaluations of learning with hypertext have shown contradictory results. Adaptive hypertext was introduced to solve some problems when learning with hypertext. This paper reports on two empirical studies comparing different forms of adaptive hypertext. In the first experiment, four treatments were realized by a combination of adaptive…
