AHIS equation describes a new model for instructional system design and develops a system based on Merrill's Component Display Theory incorporating appropriate selection of Media, Ergonomics and Navigation Structures to produce learner engaging and effective learning outcome. A significant component of the proposed model is the integration of…

This study compared linear text-based and non-linear hypertext-based instruction in a handheld computer regarding effects on two different levels of knowledge (declarative and structural knowledge) and learner motivation. Forty four participants were randomly assigned to one of three experimental conditions: linear text, hierarchical hypertext,…

This study focuses on carrying out weighted digraph-based mathematical construction of hypermedia and user navigation on hypermedia and making a presentation of "weighted" forms of known stratum and compactness. In the instructional Web design researches, the structural analysis of navigation on the hypermedia is important in modeling the…

Typical web lectures consist of two different kinds of media linked together: an audio- or video-recording and the corresponding slides or desktop recording. Both media are synchronized so that the slide or image shown corresponds to the position currently played in the time-based media stream. Web lectures are thus composite media consisting of a…

This article describes how the author applied principles of universal design to hybrid course materials to increase student understanding and, ultimately, success. Pulling the three principles of universal design--consistency, color, and icon representation--into the author's Blackboard course allowed her to change the types of reading skills…

Whether fading support for problems affects accuracy of hypertext navigation and problem performance is investigated in this study. In a student-centered e-learning environment conceptual support is added to help domain novices get an overview of the problem domain, while strategic support is provided to help domain novices get insight into the…

Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information…

Purpose: Social navigation is an emerging trend for navigation in hypermedia. With social navigation, users can be guided through large volumes of learning content by cues which integrate the browsing history of past users. Earlier papers have shown that social navigation is suitable for navigation not only in classic hypermedia but also in…

Describes the "Knowledge Board," a comprehensive integrated writing environment for professionals who write complex documents. Program functions, including navigational capabilities, an automated note card file, information sorting, information weaving, a function to organize information logically, and a revision function are examined.…

Reviews published findings from empirical studies of hypermedia learning and cognitive styles and classifies them into five themes: nonlinear learning, learner control, navigation in hyperspace, matching and mismatching, and learning effectiveness. Presents a learning model and discusses implications for the design of hypermedia learning systems.…

To counter user disorientation and cognitive overload, hypertext environments often incorporate navigational aids in the form of graphical overviews of the hypertext structure. The aim of the present experimental investigation of learning in hypertext environments was to examine the impact of such graphical overviews on learning achievement in…

This paper reports on the design strategies and technical solutions that the authors have adopted to increase interaction in a World Wide Web-Based Instruction (WBI) system aimed at supporting new didactic approaches to the subjects of urban planning and architecture through the activation of online modules at the university level. Specifically,…

Describes an integrated approach to similarity coefficients that allows multiple index dimensions to be integrated into a single, flexible navigation tool. Categorizes different types of similarity measures by the kinds of index terms they employ and describes the underlying similarity measures. (Author/AEF)

Educational Adaptive Hypermedia Applications (EAHA) provide personalized views on the learning content to individual learners. They also offer adaptive sequencing (navigation) over the learning content based on rules that stem from the user model requirements and the instructional strategies. EAHA are gaining the focus of the research community as…

Describes functionality and user interface issues associated with the design of an automated system that provides a visually based online index to multimedia information for higher education. Topics include online lectures; bibliographic access; and the need for a hypermedia system that presents an integrated view of the materials with graceful…
