Develops two-dimensional descriptions of degenerate transformations using elementary matrix algebra. (RS)

Describes an introductory physics experiment concerned with scattering particles off various force centers. The experiment uses simulation techniques and a computer. The scattering is classical, and the student examines plots of computed particle trajectories. The results illustrate the concepts of differential corss-section, total cross-section,…

Described is a microcomputer-based statistics laboratory accessible to students in grades six through eight. A variety of software is available. Some of the graphing possibilities are illustrated. (MNS)

Two posters are presented that emphasize graphing in a Halloween setting. Both provide practice in reading and interpreting bar graphs. (MNS)

GrafTalk is a powerful, easy to use, business-oriented graphics package for producing pie, bar, and line-plot graphs. GrafTalk should run on nearly any CP/M-based system that drives a graphics device through serial/parallel output port. Discusses package installation, structure, documentation, and use, plotting scientific data, and comparison with…

Describes a study to determine the relationship between the method of presentation of data in a report and reader retention, reader reaction, and reading time. Tables were effective in increasing reader retention and decreasing reading time. (JOW)

The material is designed to help pupils investigate how the value for slope in the equation of a line affects the inclination for the graph of an equation. A program written in BASIC designed to run on an Apple microcomputer is included. Worksheet masters for duplication are provided. (MP)

Graphs are viewed as extremely useful tools in communication, which enable readers to see at a glance facts that might take several paragraphs to describe adequately. An ability to read graphs critically is seen to be an important objective for any elementary curriculum, and ways to introduce them are presented. (Author/MP)

Dialog from a filmed lesson that uses graphing to explain positive and negative numbers is presented. The material highlights the responses of children. The work was also presented to a class of low, mixed-ability pupils since the filming, and the work of two pupils from this group is noted. (MP)

An instructional sequence for teaching graphing that has been extensively field tested in kindergarten through grade six is detailed. The material begins with point graphs, employs a movable y-axis to begin with minimal clutter, and has graphs constructed before reading graphs is required. (MP)

An examination of a student question concerning a calculus problem leads to a discussion of some of the symmetric properties of a specific set of polynomials. (MP)

Some experiences with a classroom computer graphics facility are recounted to show how such a facility has changed the views of some instructors teaching mathematics at the college level. Teachers are encouraged to search out and seize opportunities to acquire graphics hardware, with the added teaching capabilities promoted. (MP)
