An example is given of a class of problems whose solutions require the use of a scientific calculator in order to plot the graphs. (MP)

An alternative approach is described for presenting the idea of the derivative through the use of chords of a graph. (MP)

Some of the questions used on a test covering concepts of graphing are presented, along with a selection of students' comments and percentages of students making given responses. (DT)

Provides directions for constructing graphical alignment charts to solve a variety of mathematical physics problems. (MLH)

A geometric approach to the solution of quadratic equations and more general polynomials is based on finding points with minimum distance from the x-axis. The approach is useful in motivating the definition of complex numbers. (SD)

Important demographic trends in the United States include 1) the population's changing age profile, 2) the tendency for young people to remain single longer, 3) the widening mortality differential between the sexes, and 4) reversal of migration trends.

This article describes the organization and results of the 1990 New Zealand Children's Census. This census, which preceded a National Census, provided a powerful tool for raising statistical awareness nationwide. (Author)

Offers problems involving baseball to give students the opportunity to utilize the technology of a graphing calculator such as the TI-82 to work on the area of statistics. Gives step-by-step instructions as well as explanations. (AIM)

Cooperative groups were given transparencies of eight regular inscribed polygons and overlays of corresponding circumscribed polygons and were asked to find the perimeters and ratios of perimeter to diameter. Transparencies give students a graphic illustration of limits. Includes reproducible worksheet. (NI)

Reprints three items that appeared in the media that were developed into mathematical problems. Items include a commentary called Junk the Penny, a sale advertisement for a department store, and a sports column with statistics. Eighteen questions are provided along with answers. A graphing calculator is suggested for some problems. (PVD)

Reprints a corrected version of an article originally published in the volume 43, number 1 issue of this journal. Presents results of a national survey of technical communicators and technical communication teachers assessing the ethics of seven document design cases involving manipulation of typography, illustrations, and photographs.

Explains how the Web can be modeled as a mathematical graph and analyzes the graph structures of three national university publicly indexable Web sites from Australia, New Zealand, and the United Kingdom. Topics include commercial search engines and academic Web link research; method-analysis environment and data sets; and power laws. (LRW)

Advocates using graphs with young children to express relationships in a visual form. Describes how to teach children about graphs to encourage them to develop the ability to quantify data and the confidence to use this tool for science learning. (NB)

Takes the reader through production steps of creating an "infographic" for a high school newspaper. Give six lessons for doing infographics: (1) always accept free help; (2) if it sounds interesting, it probably is; (3) if an idea works, use it; (4) know thoroughly the "ins and outs" of the program used; (5) different is good, interesting is…
