This paper describes the genesis and purpose of our geometry methods course, focusing on a geometry-teaching technology we created using NVIDIA[R] Chameleon demonstration. This article presents examples from a sequence of lessons centered about a 3D computer graphics demonstration of the chameleon and its geometry. In addition, we present data…

According to the Merriam-Webster dictionary, a planimeter is "an instrument for measuring the area of a plane figure by tracing its boundary line". Even without knowing how a planimeter works, it is clear from the definition that the idea behind it is that one can compute the area of a figure just by "walking" on the boundary. For someone who has…

The article discusses the use of L-systems, which provide students with a unique method to construct line fractals, including the Koch snowflake, the Sierpinski triangle, and the Harter-Heighway dragon. Applets that use L-system theory offer a graphics tool that promotes geometric reasoning, sparks enthusiasm, and connects to historical themes in…

A set of programs, designed to supplement a high school or college course in trigonometry, is described. Student exploration is stressed. (MP)

At some point in their education, pre-engineering students will take physics and/or calculus. For many freshmen who aren't certain about their career paths, taking these courses is a litmus test to determine whether they have the aptitude or desire to pursue an engineering degree. Therein lies the challenge for many students in the U.S. Science,…

Educational robots are defined, their essential characteristics and features are outlined, and their educational applications and what makes them run are discussed. Classroom experiences with five educational robots--Topo, Rhino XR-2, RB5X, Hero I and Tasman Turtle--are described. (MBR)

Describes a development project for the use of computer graphics and video in connection with an inservice training course for primary education teachers in Denmark. Topics addressed include research approaches to computers; computer graphics in learning processes; activities relating to computer graphics; the role of the teacher; and student…

Screen designers for computer-mediated instruction (CMI) products must consider the motivational appeal of their designs. Although learners may be motivated to use CMI programs initially because of their novelty, this effect wears off and the instruction must stand on its own. Instructional screens must provide effective and efficient instruction,…

An exploratory study was conducted to test the assumption that multimode knowledge of results is superior to traditionally presented knowledge of results in maintaining a student's interest and attention. In addition, the relative merit of pictorial format in a lesson was compared with a basic lesson display. The study involved 32 kindergarten…

Describes an eighth grade computer literacy course in which students used spreadsheet programs to illustrate statistics for classroom presentations. Discusses the use of color and animation in graphs, and the value of active participation using technology to increase student motivation, retention, and self-expression. (AEF)

Reports on the first stage of a British phonetic training project in foreign language learning that used a repurposed videodisc developed by using the editing capabilities of an authoring tool. Topics discussed include student motivation; content issues; teaching strategies; questioning/feedback techniques; text and graphic screens; and manuals…

Discusses advantages of multimedia research reports, including critical thinking skills, student motivation, and cooperation and collaboration; describes possible components, including videodisc, compact disc, digital audio, graphics, and animation; explains the use of video report makers and hypermedia programs; and examines the role of the…
