This tutorial presents a geometric proof done by sketch to compose a square or equilateral triangle from four small boards. It then converts the procedure into a series of 12 drawing steps with Geometer's Sketchpad. The complete Geometer's Sketchpad file of this demonstration is located at: http://poncelet.math.nthu.edu.tw/chuan/dissect/2dud.html.…

The computer can be used as a tool to represent and communicate geometric knowledge. With the appropriate software, a geometric diagram can be manipulated through a series of animation that offers more than one particular snapshot as shown in a traditional mathematical text. Geometric constructions with the computer enable the learner to see and…

Defines virtual manipulatives and stresses their advantages for classroom use. Presents examples on the Internet and discusses current and potential use of virtual manipulatives. (KHR)

Investigates the effects of computers and Internet technology on teaching and learning. Presents electronic examples that integrate well with high-quality mathematics instructional programs. (KHR)

The process of turning symbols into a mathematical sculpture has never been easier. A copy of Maple V release five and a Web browser configured with a VRML plug-in such as the Cosmo Player is necessary to do these activities. Maple V furnishes the computing environment with the capability of allowing for concentration on the mathematical…

Presents activities for using the Internet to teach mathematics. Includes various web sites. (NB)

Shows how the joint use of a dynamic geometry program and a spreadsheet can provide a computational environment for exploring geometry on plane lattices that lessens the risk of developing the false empiricist view of mathematics often associated with the use of information technology. Contains 17 references. (Author/ASK)

Takes a theme from "IMPACT Maths" and works it into a spreadsheet activity to display data in bar charts, pie charts, and line graphs. (ASK)

Presents a student mathematics project aimed at developing students' skills with computer spreadsheets and using the Internet to give students an appreciation of the many ways that mathematics can describe common everyday items--in this case the bicycle--and make them aware of their own role in learning. (ASK)

Investigates ways to analyze change in various contexts. Focuses on computer technology providing contexts for children's investigations of patterns of change and helping to develop foundational ideas of algebra and calculus. Discusses relationships between patterns of change, fundamental algebraic notions as linear and nonlinear functions, and…

Considers how the World Wide Web is used by mathematics educators and describes a multiphase teaching experiment designed to determine if the World Wide Web is a viable means of accessing course materials. Discusses the resources involved in supporting such access. (DDR)

Presents an activity in which students use computer-based spreadsheets to find out how much grain should be added to a chess board when a grain of rice is put on the first square, the amount is doubled for the next square, and the chess board is covered. (ASK)

Shares experiences with using "The Wall", a number patterns spreadsheet idea developed by Dave Shiers, with children in a middle school. (ASK)

Presents ways of connecting mathematics to students' lives. Provides information on CamMotion, software that uses video and computer technologies to bring mathematics and students together in innovative ways. (ASK)

Describes PC Logo, an instructional tool that can be used for teaching and enhancing a student's knowledge of graphs and geometric concepts. (CCM)
