Discusses how hypermedia interfaces can use graphic design and language to help users of hypermedia programs to structure a cognitive approach to information retrieval. Argues that such interfaces should acknowledge the medium's limits, identify authorship levels, define a program model, provide overviews, and narrow the navigation functions. (SR)

This study found that a Kohonen self-organizing map (SOM) algorithm for browsing can categorize a large and eclectic Internet-information space into manageable sub-spaces that users can navigate to find relevant home pages. An automatically generated concept-space algorithm for searching was shown to enhance keyword-based Internet searching.…

Argues that social studies teachers should offer their students the necessary critical-thinking skills to help them navigate the Internet. Presents an overview of six criteria, with accompanying questions, to assist students in determining the reliability and usefulness of information sites and allowing them access to the valuable information…

Discusses problems with navigation in hypertext systems, including cognitive overload, and describes a study that tested information visualization techniques to see which best represented the underlying structure of Web space. Considers the effects of visualization techniques on user performance on information searching tasks and the effects of…

Describes World Geography, a commercial Web subscription geographic information source. Discusses its use as a reference source, including content, navigation, and links; the teaching module; integrating technology into the curriculum; pricing; and vendor information. (LRW)

Describes DVD (Digital Videodisc, or Digital Versatile Disk) technology which offers the ability to combine laser disc and CD-ROM programs to create a multimedia platform that can deliver high quality, full-motion video and an on-screen user interface for interactive navigation and branching for providing group or individual instruction. (LRW)

Discusses the development and results of usability testing of Washington State University's Web-based OPAC (online public access catalog); examines how easily users could navigate the catalog and whether they understood what they were seeing; and identifies problems and what action if any was taken.

This article, which originally appeared in the May 1998 issue of "Mathematics Teaching in the Middle School," explores the runway numbering system. The activity described in this paper furnishes an excellent setting for discussing rounding rules and, in particular, what to do if the digit to the right of the place to be rounded is equal to five. A…

The goal of this work is to extend the theoretical understanding of the relationship between hippocampal spatial and memory functions to the level of neurophysiological mechanisms underlying spatial navigation and episodic memory retrieval. The proposed unifying theory describes both phenomena within a unique framework, as based on one and the…

For the last three decades, the engineering higher education and professional environments have been completely transformed by the "electronic/digital information revolution" that has included the introduction of personal computer, the development of email and world wide web, and broadband Internet connections at home. Herein the writer compares…

This paper provides a brief description of Hyper-G, the first second-generation hypermedia system. The first section identifies problems with first generation hypermedia systems. The following sections discuss the new concepts that are implemented in Hyper-G, including user accounts and billing, structuring of data, caching and replication, native…

The World Wide Web (WWW) acts as a multimedia Internet, navigable via Web browsers. Web browsers (Mosaic, Netscape, Cello, WinWeb, etc.) read files treated in HyperText Mark-up Language (HTML) and display interactive pages to users. Teachers with computer-mediated classrooms or labs can use HTML and Web browsers to create multimedia presentations…

This book is designed to help instructors and students master and teach the Wilderness Education Association (WEA) curriculum while in the field. It is formatted in self-contained lesson plans which describe the overall goal, the specific objectives, the body of knowledge, and the materials necessary for teaching about a specific topic within the…
