This case study investigated the impact of a spreadsheet (EXCEL) exploration on the understanding of statistical graphs among twenty Singapore secondary school students of average ability. Four EXCEL templates were constructed to allow students to explore four aspects of statistical graphs: zero in scale, effect of different scales, size…

This guide to the discovery, analysis, production, communication, and use of statistical information through graphic forms produced by a computer is designed to enable researchers to conduct their analyses and report research results more effectively. It is designed both for individuals with little knowledge about the use of statistical graphs or…

Use of Logo to teach statistical ideas is proposed for students in grades 5-10. Procedures and diagrams are suggested, with program listings for four models for graphs. (MNS)

Given is an example of the solution of maximum-minimum problems by replacing differentiation techniques with microcomputers and simple BASIC programs. (MNS)

Three activities with Knuth functions are discussed and illustrated, with sample computer programs listed. (MNS)

Presents a graphing activity to show transverse and longitudinal waves using spreadsheets. (Author/NB)

Discusses the use of a dynamic geometry software package to improve teaching of graph theory in basic graph sketching and in isomorphic, bipartite, and planar graphs. (JRH)

The characteristics of unidimensional ability estimates obtained from data generated using multidimensional compensatory models were compared with estimates from non-compensatory item response theory (IRT) models. The least squares matching procedures used represent a good method of matching the two multidimensional IRT models. (TJH)

Discussion of expert systems focuses on a national survey that gathered information concerning the attention and investment given to expert systems by managers and computer professionals in a variety of fields. Highlights include uses of expert systems, types of computers and software used, and expert systems shells and development costs. (18…

Reviews two software programs: "The Graph Club" which makes learning graphs "magical and exciting"; and "WiggleWorks," an "exciting" reading curriculum on CD-ROM. (SR)

Explains format, style rules, and lexicographic conventions that improve clarity and precision in a technical glossary. Discusses general rules, rules of style, rules of grammar and syntax, and rules for figures. Describes the computer display techniques and file management system used to develop such a glossary. (SR)

Topics such as linear and nonlinear equations and inequalities, compound inequalities, linear and nonlinear absolute value equations and inequalities, rational equations and inequality are commonly found in college algebra and precalculus textbooks. What is common about these topics is the fact that their solutions and graphs lie in the real line…

The graphing of intricate curves and the fundamental theorem of algebra lead to a third discovery with microcomputers: Lagrange polynomials. Teaching suggestions for helping students to explore continuous change, interpolation, roots, and shifting and symmetry are presented, with a computer program listing. (MNS)

Presented is an interactive Applesoft BASIC program that graphically demonstrates the central limit theorem. It can be used as the basis of a lab to illustrate the main conclusions of the theorem. (MNS)

A function-graphing program is given, plus a series of experiments that students can carry out using the program. (MNS)
