This article describes a number of problems every educational measurement specialist should be prepared to confront before using microcomputers to support test-related activities, including problems with hardware, with software, and with implementing a system. It concludes with a checklist for planning a microcomputer application. (BW)

The proceedings of the 24th annual meeting of the Psychology of Mathematics Education North American Chapter (PME-NA) contains research reports, plenaries, and poster presentations. Papers include: (1) "What Do We Believe about Teacher Learning and How Can We Learn With and From Our Beliefs?" (Deborah Loewenberg Ball); (2) "Toward Evidence for…

The report describes a mathematical modelling activity of a natural phenomenon (transmission of hereditary characters in a codominance case) using the concept of model as a theoretical instrument. The chosen tool enables us to show how the construction of a link between reality and a model is related to the evolution of the graphical…

This guide is linked to a science curriculum and was designed for use by those involved with early childhood education. The goal of this document is to enable caregivers and teachers to use the curriculum in a more varied, stimulating, and developmentally appropriate way. Topics discussed include student attitudes toward mathematics, parent…

Many of today's popular sports are based around the use of a ball yet none are alike. In fact, they are all designed with specific characteristics in mind. In this activity, students investigate different balls' ability to bounce and represent the data they collect graphically. This activity uses a time frame of 100 minutes. (Author/SOE)

This paper reports on efforts to design a computer-based instructional unit for 7th grade students that would not only address state standards but would also provide some groundwork for the students' subsequent formal study of algebra. SimCalc Mathworlds software was used to explore the same motion from different perspectives. The overall…

Compares Illinois' funding formula with a mathematical model for resource compensating formulas. Describes the variables used (including district enrollment, wealth, tax effort, and state guaranteed valuation). Uses graphs to illustrate varying equity effects of the formula for K-12, K-8, and high school districts, both statewide and in selected…

Data on 2,380 searches of online information retrieval systems are analyzed using a mathematical model to determine the relationship between two measures of effectiveness--documents read and relevant references. The nature and relative merits of these two variables are discussed, as well as the findings, and seven references are listed. (RBF)

The design of a "percent computer" that uses the concept of similar triangles is presented. The device can be easily made by elementary and secondary pupils out of graph paper and string. Sample student problems are included. (MP)

Illustrates the diverse ways in which the computer spreadsheet can be used by both teachers and students as a problem-solving tool in high school mathematics, and provides detailed examples of spreadsheet use in word problems. Discusses the functions of spreadsheet tables, columns, and graphs. (AEF)

Outlines a pair of projects used in introductory calculus that are inspired by techniques archaeologists use in the analysis of pottery. These real-world application problems appeal to students who are not necessarily interested in the standard application of calculus. (Author/DDR)

Presents strategies that utilize graphing calculators and computer software to help students understand the concept of minimizing the squared residuals to find the line of best fit. Includes directions for least-squares drawings using a variety of technologies. (DDR)

Described are several spreadsheet templates which use the functions of iteration and logical look-up which allow students to calculate and graph quantum mechanical functions and to simulate rotational and vibrational energy level and spectra. The templates are listed in the appendix. (KR)

Appropriate uses for graphics calculators in precalculus and calculus are discussed. The functions of Casio, Sharp, and Hewlett-Packard brand calculators are stressed. A "Stress Test" for graphics calculators designed to illustrate common errors and to furnish examples of tasks which cannot be completed on these instruments is provided.…

Describes a computer applications course developed for undergraduate biology students (primarily sophomores) to teach word processing, database and spreadsheet programs, graphing programs, telecommunications, and file transfer procedures. AppleWorks software is discussed, course content is explained, and the microcomputer laboratory is described.…
