In the context of exploring educational hypermedia on the World Wide Web, this paper presents a history visualization that helps learners reorganize explored contents to find what Web sites they should visit next. Learning-by-exploration is discussed as it relates to educational hypermedia, including the "Get Lost in Hyperspace" problem,…

This paper shows how to use design patterns for building educational multimedia applications. The first section summarizes design issues related to organizing the information, the organization of the interface, and implementation. Navigating through information is covered in the second section, including problems, motivations, and solutions, and…

Presents a matrix that can serve as a tool for designing the information architecture of a Web portal in a logical and systematic manner. Highlights include interfaces; metaphors; navigation; interaction; information retrieval; and an example of a children's Web portal to provide access to museum information. (Author/LRW)

This paper reports on an ongoing work in designing and developing a personalised search tool for teachers' online searching using Google search engine (repository) for the implementation and testing of the first research prototype.

Discusses the need for usability testing for information systems and for librarians to recognize what makes computer interfaces either easy or difficult to use. Highlights include user friendliness; navigation; standards; visual appeal; layout and design; feedback; help screens; and the usability-testing process. (LRW)

Purpose: To outline the conceptual and technical difficulties encountered, as well as the opportunities created, when developing an interlinked collection of web-based digitised primary sources on eighteenth century London. Design/methodology/approach: As a pilot study for a larger project, a variety of primary sources, including the "Old…

The DR-LINK (Document Retrieval through Linguist Knowledge) search system was created to help automate the process that research librarians use to convert information needs, as stated by users, into the information retrieval process. DR-LINK resulted from participation in the United States Government initiative called Tipster that was sponsored by…

This experimental study investigated internal (psychological characteristics) and external (World Wide Web site features) factors influencing learning and disorientation in Web navigation. The research design was a two-factors ANOVA (ANalysis Of VAriance) with mode of navigation (linear, nonlinear) and distracters (i.e., the presence of…

This paper promotes further discussion and analysis of interactivity in learning environments and contains a classification of interaction types appropriate for consideration in multimedia settings. Through an examination of related factors associated with navigation and control, a matrix of interactive dimensions is proposed. (Author)

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…

A portal is the digital infrastructure for an online campus. Community portals, online service portals, and enterprise-wide platforms represent the three basic portal variations available for online campuses. They are differentiated by the offices represented, the campus audience served, and benefits provided to the school as a whole. (PGS)

This study of undergraduates investigates how cognitive style, online database experience, and task type influence users' search behavior on the Web. Considers time spent, the number of nodes visited, search performance, navigational style, and ways to improve Web interfaces and Web user training programs. (Author/LRW)

As more archival metadata and archival records become available online, providing effective interfaces to those materials is increasingly important to give users access. This article describes five approaches from the hypertext and visualization research communities which can be used to improve such access: (1) navigating hierarchical structures,…

Summarizes the issues, debates, and decisions that helped to shape "The Washington Post's" online service, Digital Ink. Highlights include: differences between online and print versions of the newspaper, structure of the user interface, organization of information, content, searching and navigation, and advertising.

This paper proposes a model for a general interface between people and Computer Algebra Systems (CAS). The main features in the CAS interface are data navigation and the possibility of accessing powerful remote machines. This model is based on the idea of session management, in which the main engine of the tool enables interactions with the…
