Describes the components of a hypertext system and discusses possible applications from the model of hypertext as a writer plus reader phenomenon. The role of semantic nets is described within the context of both the writer and the reader, and the relevance of hypertext techniques to computer software and expert systems is discussed. (42…

Describes current developments in microcomputer technology, including CD-ROM, the 80386 microprocessor, and the graphic user interface. It is argued that, as the information handling capacity of microcomputers increases, the microcomputer industry will increasingly market information to end users, and the library will be challenged to provide the…

Shows a series of Euclidean equations using the Euclidean algorithm to get the greatest common divisor of two integers. Describes the use of the equations to generate a series of circles. Discusses computer generation of Euclidean circles and provides a BASIC program. (YP)

Suggests computer graphing as a topic for computer programing. Reviews Apple II computer graphics information and gives suggestions for writing the programs. Presents equations to help place information onto the screen with proper coordinates. (MVL)

Explains the Intelligent Maintenance Training System that allows a nonprogramming subject matter expert to produce an interactive graphical model of a complex device for computer simulation. Previous simulation-based training systems are reviewed; simulation algorithms are described; and the student interface is discussed. (Contains 24…

SIGMA (Simulation Graphical Modeling and Analysis) is a computer graphics environment for building, testing, and experimenting with discrete event simulation models on personal computers. It uses symbolic representations (computer animation) to depict the logic of large, complex discrete event systems for easier understanding and has proven itself…

The use of a computer software package called "Exploring Measurement, Time and Money--Level 1" to help children explore many different arrangements of data and the effects of changing that data is presented. Activities which may be used to prepare students for this instruction are described. (CW)

Discusses the basic technical concepts of using graphics in World Wide Web pages, including: color depth and dithering, dots-per-inch, image size, file types, Graphics Interchange Formats (GIFs), Joint Photographic Experts Group (JPEG), format, and software recommendations. (AEF)

The objective of this article is to investigate the computer animation and virtual reality technologies for developing a virtual marine museum. The museum consists of three exhibition areas. The first area displays fishes in freshwater, including creeks, rivers, and dams in Taiwan. The second area exhibits marine ecology and creatures of different…

In this paper, I review both mathematics education and CSCL literature and discuss how we can better take advantage of CSCL tools for developing mathematical proof skills. I introduce a model of proof in school mathematics that incorporates both empirical and deductive ways of knowing. I argue that two major forces have given rise to this…

Look no further than to the popularity of C-SPAN's annual video documentary competition for middle and high schoolers, and it's obvious that video editing, and the technology that comes with it, is important to today's students. In the past it was a complex, involved, and expensive process. Video editing is now within the reach of anybody with a…

This ERIC Digest discusses concept mapping, a technique for representing the structure of information visually. Concept mapping can be used to brainstorm, design complex structures, communicate complex ideas, aid learning by explicitly integrating new and old knowledge, and assess understanding or diagnose misunderstanding. Visual representation…

Arguing that females need instruction in visuo-spatial skills before adolescence, when they begin to lag behind males in the development of these skills that are so strongly correlated with success in technical careers, this paper discusses the use of the three-dimensional and spherical graphics of ExperLOGO to develop spatial skills in students…

In an increasingly technological society, there is a social need for designing communication technology around the perceptual abilities and cognitive strategies of people. A growing demand for information has created additional pressure on emerging communication technologies to provide electronic alternatives to the printed page. Design depends…

The concept of the personal computer (PC) as a stand-alone, single-user computer has had its day. The 8-bit processors cannot support the newer applications, and, although there have been some advances in 16-bit microprocessors, the "second generation" software is immature and does not work well. The immediate problem for colleges and universities…
