Discusses the use of computer graphics to introduce the concepts of derivative and tangent line using the iteration of functions, especially linear functions. (MKR)

Describes the Knowledge Gateway Project (KGP), a program that emphasizes intensive use of computer technology to help at-risk high school students. Teacher training in the use of Macintosh computers and appropriate software is discussed, self-paced lessons are described, and changes in student behavior are reviewed. (LRW)

A computer program that replaces a set of pharmacology and physiology laboratory experiments on live animals or isolated organs is described and illustrated. Five experiments are simulated: dose-effect relationships on smooth muscle, blood pressure and catecholamines, neuromuscular signal transmission, acetylcholine and the circulation, and…

Described are improvements for the computer efficiency of the two midpoint scan-conversion algorithms used to draw ellipses. Included are computer programs written in C programing language. (JJK)

Describes the use of interactive television in distance higher education based on experiences of an accredited MBA program at Ball State University (Indiana). Discusses how graphics were designed and used to deliver accounting instruction and feedback to homework assignments. Describes the presentation software used. (AEF)

Describes a study of undergraduates that compared navigational study strategies, the extent of lesson coverage, and attitudes about learning with three types of hypermedia lessons to examine how learners use different types of graphical browsers in a learner-controlled hypertext system to construct personalized representations of the content…

We present a new highly interactive computer animation tool to increase the mathematical skills of deaf children. We aim at increasing the effectiveness of (hearing) parents in teaching arithmetic to their deaf children, and the opportunity of deaf children to learn arithmetic via interactive media. Using state-of-the-art computer animation…

There is much research that documents what many teachers know, that students struggle with many concepts in probability and statistics. This article presents two sample activities the authors use to help preservice teachers develop ideas about how they can use technology to promote their students' ability to understand mathematics and connect…

In this paper, results from a subset of the Purdue Spatial Visualization Test and a self-efficacy test developed by the authors are presented to determine whether certain object shapes, orientations, and types of rotations in standard spatial ability tests cause more difficulty than others and whether a solid object, which includes shading to…

Critical reasoning has been recognized as a valuable educational goal since the end of the nineteenth century. However, the educational programs to reach this goal have changed dramatically during the twentieth century and moved to a dialogic approach. The shift to dialogism in programs to promote critical reasoning brings challenges concerning…

Digital Chisel is a user-friendly multimedia authoring tool for helping students and teachers to tutor/teach the computer. It can be used as a visual presentation tool, as a tool to provide individualized instruction and as a tool to help students learn using a variety of visual and auditory modes. Interactive presentations can be designed without…

The purpose of this paper is to report specific motivational requirements within each motivation category of Keller's ARCS (Attention, Relevance, Confidence, Satisfaction) model (1991) based on data collected on students' reactions to a computer-assisted learning lesson that incorporated motivational strategies in its design. Interview techniques…

This report describes the development of a project designed to enable high risk high school students to acquire the skills necessary to create computer art. The project was based on a perceived need for the development of a curriculum in computer graphics that would motivate high risk students to acquire skills that could lead to a long term…

The first section of this paper on World Wide Web applications related to dynamic geometry addresses dynamic geometry and teaching, including the relationship between dynamic geometry and direct manipulation, key features of dynamic geometry environments, the importance of direct engagement of the learner using construction software for…

The effects of visual grouping strategies involving animated and static graphic presentations on learning were studied. Also studied was the ability of students to learn a scientific rule presented incidentally in an animated sequence in the hope of replicating results from previous research. A total of 39 fourth graders participated in an…
