Discusses the use of Calculator Based Ranger (CBR) in mathematics classrooms. Provides a classroom activity in which students graph walking in different directions and speeds. Presents student work and testing. (ASK)

Stresses the value of graphing and computer algebra systems calculators when teaching about waves. Discusses how to input data into these calculators. Highlights the Texas Instruments' (TI) Web site at http://www.ti.com. (YDS)

Describes an activity in which students are given a set of designs and are required to use their electronic grapher to reproduce the designs. The activity reinforces students' understanding of lines and of the formula for a linear function. (MKR)

This project description is designed to show how graphing calculators and calculator-based laboratories (CBL) can be used to explore topics in the physics of sound. The activities address topics such as sound waves, musical notes, and chords. Teaching notes, calculator instructions, and blackline masters are included. (MM)

Discusses the graphing and other technical capabilities of the TI-83. Demonstrates possible uses of it in mathematics classrooms. (ASK)

Focuses mainly on a common example in technology-rich mathematics curricula, namely the line of best fit, followed by a discussion of two additional examples, interpolating polynomials and complete graphs. (ASK)

The use of a computer to help honors second-year algebra students graph quadratic and higher-order polynomials is discussed. Sample computer programs are included. (MP)

Addresses the "T-cubed" or Teachers Teaching with Technology program and their courses utilizing hand-held technology such as graphic calculators, data-loggers and the TI-92 hand-held computer. Describes practical experiments involving discharge, a temperature probe, and an oscillating water sprinkler. (AIM)

How the use of calculators can illuminate mathematics and improve the level of problem-solving discussion in classes is presented. (MP)

Explores ways in which various technologies can be integrated to teach the transformation of graphs in an interactive and dynamic way. Discusses how the use of graphic calculators, a spreadsheet, graph plotter, presentation package, and an interactive whiteboard can be combined to give students the opportunity to investigate, understand, and have…

Two microcomputer-based laboratories, the motion detector and the sound detector, are discussed in terms of their affects upon the facilitation of an understanding of graphs and their ability to aid in the development of conceptual understanding from graphical analysis. The author relates experiences in using these labs with high school students…

It is difficult to incorporate long term studies such as ecology into classroom settings. Discusses how to reach and download research center data available on the web. Recommends Long Term Ecological Research (LTER) sites for downloading and interpreting data. Explains the downloading procedure using a Netscape browser, and uses Excel and Lotus…

Identifies conceptions that students have with regard to the construction of graphs representing everyday situations in a computer learning environment using a GRAPHIC plotter, and examines the resistance of alternative conceptions to formal instruction. Following instruction, no significant improvement in students' performance was observed.…

Provides a lesson that focuses on three-dimensional graphing, contours, and topographical maps using computer spreadsheets. (ASK)

Offers information on a project to improve students' understanding of derivatives. Students use the software package "Cactusplot" which allows them to calculate the slope at various points, and "Graphical Analysis III" software to graph the data and modify the graphs if necessary. (ASK)
