Describes the conceptual foundations for the Gateway to Educational Materials (GEM) metadata framework including adoption of the Dublin Core Element Set as its base referent, and extension of that set to meet the needs of the domain. Discusses selection and structuring of the units of description. Examines metadata generation, the association of…

Introduces a prototype system for devising and using a metadata vocabulary for data retrieval, based on a project at the United States Department of Agriculture. A unified information-access system called REEIS (Research, Education, Economics, Extension Information System) is being designed to provide a knowledge base of programs, projects, and…

Interacting cognitive subsystems (ICS) is proposed as a unified cognitive theory that can be used as the basis for representations in human-computer interaction, and two approaches based on the theory are described: one entails the description of cognitive task models, and the other entails the production of less complete diagrammatic notations.…

Describes the use of Spotfire, a starfield visualization tool, to generate interactive visualizations of log data, ranging from aggregate views of all Web site hits in a time interval to close-ups that approximate the path of a user through a site. Highlights current efforts and provides examples of the visualizations created in Spotfire.…

Suggests that a solution to the inadequacy and passivity problems with push and pull technologies could be in a combination of both, with an active component, adding more intelligence to the whole process of information and knowledge dissemination and supply. Describes basic principles of activity components in intelligent systems, and some…

Lists steps to follow when planning a course online: assess needs and necessary conditions to satisfy them; estimate development cost, effort, and implications; plan the virtual classroom; design the virtual classroom; prepare and distribute contents; enable communication; implement online student assessment methods; implement class management…

Describes the design for a digital collection service, an independent mechanism for introducing structure into a distributed space, research by Cornell Digital Library Research Group (CDLRG). Summarizes the component-based digital library architecture that is the context for the design. Describes a collection abstraction that is appropriate for…

Discussion of distance education outlines general strategies for effective distance learners, methodologies students have adopted to learn online, and their preparation techniques. Topics include student personality characteristics, reasons for pursuing education online, technology increasing student motivation, collaborative learning, and use of…

Describes CaMILE (Collaborative and Multimedia Interactive Learning Environment), an online forum for collaboration and reflection. Topics include project-based learning, collaborative domain-relevant student discussions, a model for understanding collaboration tool use, examples of using CaMILE in various university disciplines, and use of the…

This study developed an analytical approach to detecting groups with homogenous usage patterns in a Web-based information system. Principal component analysis was used for data reduction, cluster analysis for categorizing usage into groups. The methodology was demonstrated and tested using two independent samples of user sessions from the…

Reports on results of an exploratory study of perceptions of collections by librarians in an academic library that provides both traditional and networked information services. Five librarians from a Midwestern university library were interviewed. Findings indicated an uncertainty about the virtual world in two particular areas: collection and…

Describes a novel design of a Table Browser for casual users of statistical data. Focuses on the overall system architecture and the user interface. Describes the prototype interface and presents results of experiments testing the efficacy of the multi-threaded data flow. (AEF)

Few would dispute that much has changed in the field of international credential evaluation in the past twenty years. Support for fully staffed international admissions has waned as directors of admission have faced increasing challenges in the areas of recruitment and enrollment management while being faced with budget constraints and increased…

This article presents interesting articles that explore several different areas of reference assessment, including practical case studies and theoretical articles that address a range of issues such as librarian behavior, patron satisfaction, virtual reference, or evaluation design. They include: (1) "Evaluating the Quality of a Chat Service"…

When the human genome project was conceived, its leaders wanted all researchers to have equal access to the data and associated research tools. Their vision of equal access provides an unprecedented teaching opportunity. Teachers and students have free access to the same databases that researchers are using. Furthermore, the recent movement to…
