Examines the use of a computer simulation program as a tool to help in the understanding of wave phenomena. After analyzing some of the main difficulties and common misconceptions about waves, features of the "Making Waves" software package are described. Figures showing a typical monitor display are presented. (YP)

Describes optical scanners, including how the technology works; applications in data management and research; development of instructional materials; and providing community services. Discussion includes the three basic types of optical scanners: optical character recognition (OCR), optical mark readers (OMR), and graphic scanners. A sidebar…

Addresses present and future capabilities of online journals. Notes differences between paper and online journals including the ease of publication compared to paper, the importance of hypertext links, color graphics, and immediacy of communication with authors. Discusses advantages and disadvantages, three main formats (simple text, scanned…

Discusses the use of multimedia technology in multicultural elementary and secondary school classrooms. Highlights include types of multimedia technology, including hypermedia, voice/sound digitizers, scanners, CD-ROMs, videodiscs, and other video equipment; lesson plans for teachers; ideas for student group projects; and sources for multimedia…

The existing methods for graphically illustrating projection and coordinate systems for manual and computer-aided drafting and design are examined. Inconsistencies in methods used to graphically depict first and third angle projection in texts and the lack of attention in the relationship of projection to coordinate systems are noted. (KR)

An algorithm is described for generating smooth curves of first-order continuity. The algorithm is composed of several cubic Bezier curves joined together at the user defined control points. Introduced is a tension control parameter which can be set thus providing additional flexibility in the design of free-form curves. (KR)

The focus of this article is on how computer graphics can be integrated throughout the engineering graphics curriculum to increase visual perceptual skills. Visual perception is defined, the need to develop it is described, and methods which engineering graphics educators can use to develop it are outlined. (KR)

Effects of animated presentations and practice were studied in a computer-based science lesson involving 55 fourth graders and 64 fifth graders. Results suggest that animated graphics can promote learning, and they demonstrate successful application of interactive graphics in the design of cognitively based practice activities. (SLD)

Summarizes the conclusions reached by art educators who discussed the kinds of computer knowledge and skills required by preservice teachers. Identifies two categories: fine arts (visual expression, graphic design, and aesthetics) and art education (knowledge about hardware and software, applications, management, and interdisciplinary…

Examined how exposure to a program of fractal computer graphics affected the perceptual sensitivity of sixth-grade students (n=197) to the natural visual environment. MANCOVA analysis of collected data and students' written responses to questions indicated that environmental perceptual sensitivity was higher for subjects exposed to fractal images.…

Discussion of multicultural classrooms and English-as-a-Second-Language focuses on a study that investigated the relationship of learners' language backgrounds and different computer graphics display strategies. Four versions of hypertext instruction with identical text and different levels of computer graphics displays were tested on graduate…

Relates the story of the creation of an exploratory art technology class at Hadley Junior High School (Illinois) and its development over the past decade. Describes the equipment required to conduct the course, resources available for teachers creating similar courses, and student projects. Suggests ways to make the course multidisciplinary. (DSK)

Asserts that current software makes it easy for instructors to integrate visual displays into their lectures. Reviews the benefits of using visual displays, provides a taxonomy of visual displays, and proposes principles for constructing each type of display. Includes reproductions of related computer graphic screens. (MJP)

In this article we describe a mathematical microworld for investigating car motion on a racing course and its use with a group of grade 12 students. The microworld is concerned with the mathematical construction of courses and functions which describe car motion. It is implemented in the computer algebra system, Maple[R], which provides the means…

Most children's books are filled with pictures, yet when schools design curricula to teach writing, they often ignore the role of visual images in the writing process. Historically, methods for teaching writing have focused on text. Even relatively recent techniques like brainstorming and story webbing still focus on verbal information. In some…
