Discussion of transactions in computer-based instruction for ill-structured and visual domains focuses on two transactions developed for meteorology training that provide the capability to interact with video and graphic images at a very detailed level. Potential applications for the transactions are suggested, and early evaluation reports are…

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…

Discusses the possible futures of telecommunications and interactive television and describes the Internet and services now available through it. Topics addressed include access to the Internet; resources available; access costs; user-friendly graphical interfaces; the digital video channel, used for videoconferencing and experimental projects;…

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)

Describes the development of an interactive teaching and learning model involving Desktop Videoconferencing (DVC) and other audiographic facilities for undergraduate mathematics. The experiment demonstrated that it was possible to integrate DVC with computer applications/graphics software to represent algebraic, geometric, and numeric concepts.…

Describes the advantages in having children develop their own art rather than downloading images or clip art from computers or the Internet. Topics include developing art skills; learning through creating; self-expression; self-confidence gains; observation skills; and creativity and problem solving. (LRW)

Using computer graphics such as drawings, charts, and figures in textual instruction can enhance learning by providing a spatial concept of what is being read. It is important for instructional designers to determine the specific instructional objectives to be met, what level of comprehension they want learners to achieve, and how to use the…

The MARIE project explores knowledge-based information retrieval of captioned images of the kind found in picture libraries and on the Internet. MARIE's five-part approach exploits the idea that images are easier to understand with context, especially descriptive text near them, but it also does image analysis. Experiments show MARIE prototypes…

This column describes technology resources that teachers can use to support a celebration of reading throughout the year. In addition to online sites, other tools such as word processors, graphic drawing tools, and photo editors are suggested.

This paper extends work on the construction of instructional modules that use graphical and simulation techniques for teaching statistical concepts (Marasinghe, et al. 1996; Iversen and Marasinghe 2001). These modules consist of two components: a software part and a lesson part. A computer program written in LISP-STAT with a highly interactive…

Today computer music is the dominant form of reproduced music and computers are widely available in the home and in science laboratories. The advent of new technology prompts us to rethink not only how we teach, but also what we teach. In this article I present a possible new approach to the teaching of sound based around these new technologies.…

Statistical and geographical literacy is essential for our daily lives. A new web portal for middle school students, published on the federal government statistics website, supports geographic and statistical education by providing age-appropriate online learning activities that teach how to use statistical summaries and their graphic…

This document consists of nine issues of the National LOGO Exchange Newsletter (NLX). Each issue contains several articles as well as regular features and departments. The lead articles in this volume are entitled: (1) "Twenty Powerful Ideas" (Molly Watt); (2) "Multiple Turtles without Sprites" (James Hurley); (3)…

This paper describes Macintosh features which can be used in writing interactive programs. A program written in Microsoft BASIC (version 2.0 interpreter) is described which is used to produce plots of electric field produced by two-dimensional arrangements of point charges. It demonstrates the use of pull-down menus, windows on the screen, the…

An Open University project was planned to develop a set of computer assisted learning (CAL) microcomputer programs for a second level, summer school physics course, scheduled to begin in 1982. Major project aims were the development of an underlying system to effectively use medium resolution graphics with a simple animation capability;…
