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…

Growing consensus among policy makers and educators alike suggests that our education system must be transformed to address the needs of a global society as well as the needs of the 21st century student. Often overlooked as a resource, students can contribute a valuable perspective on education. The purpose of this study, therefore, was to learn…

Across the globe, progressive universities are embracing any number of MUVEs (multi-user virtual environments), 3D environments, and "immersive" virtual reality tools. And within the next few months, several universities are expected to test so-called "telepresence" videoconferencing systems from Cisco Systems and other leading…

Mixed methods were adopted to explore the effects of student-generated visualization on paper and on computers as a study strategy for middle school science concept learning. In a post-test-only-control-group design, scores were compared among a control-group (n=28), a group that was trained to visualize on paper (n=30), and a group that was…

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…

The purpose of this book is to assist pre-service and in-service K-12 teachers in selecting instructional strategies and media that will ensure that students achieve desired learning objectives and to illustrate how teachers can develop more effective curriculums by engaging in applied research. The first five chapters comprise Part 1, an overview…
