Sample materials from a primary training packet are included. The packets were developed as a part of a teacher development program aimed at improving elementary mathematics by giving teachers practical ideas. The sample student materials are drawn from the areas of geometry and oral mathematics. (PK)

Argues that while microcomputer and graphing calculators have evolved to a stage where they should be used routinely by mathematics students at all levels, there is sometimes potential to mislead students with computer generated graphs. Examples are included. (PK)

Describes how interactive programs for scientific modeling may be created by using spreadsheet software such as LOTUS 1-2-3. Lists the advantages of using this method. Discusses fractional distillation, batch partial melting, and combination models as examples. (CW)

Describes seven estimation and counting activities appropriate for an early childhood classroom. Includes suggested methods for going beyond the prescribed activities. (PK)

Discusses some important components of instruction on fractions in the early childhood years. Argues that fractions should be included in the early childhood curriculum and suggests various activities and materials. (PK)

Presents a new method to teach the subject of evaporators which is both simple enough to use in the classroom and accurate and flexible enough to be used as a design tool in practice. Gives an example using a triple evaporator series. Analyzes the effect of this method. (CW)

Provides mathematical activities in reproducible format for students in grades seven through ten. Intended to review and reinforce mathematical symbolism, concepts and relationships appropriate for middle school students. The game format is modeled after a television game show. (PK)

Activities are given to assist students in seeing a rationale for the difficult algorithms we teach for fractions. Both interpretations of fractions and operations with fractions are discussed. (MNS)

This paper examines issues related to the statistical power of impact estimates for experimental evaluations of education programs. The focus is on "group-based" experimental designs, because many studies of education programs involve random assignment at the group level (for example, at the school or classroom level) rather than at the student…

This book features a comparative study of American and Chinese mathematics teachers. How teachers understand the content of mathematics and their practice of mathematics teaching is examined. The differences between Chinese and U.S. teachers' knowledge of mathematics for teaching are documented, and how Chinese teachers' understanding of…

Since 1964, colleges have been sending data to the College Board Validity Study Service in order to determine the degree to which measures used in admissions predict college performance. These studies have allowed for the monitoring of general trends in the relationship of SAT scores and high school grades with freshman grades. Beginning in the…

A description is given of a game simulation course, developed for a full year of general mathematics credit. It traces a rock-and-roll band, with each student acting as manager. Ten activities are outlined. (MNS)

Four activities focus on estimation and mental computation. Each consists of a game that can be used on an overhead projector. The content involved finding costs and estimating sums, products, and percents. (MNS)

Use of the hand-dialed, transparent, nonelectronic SEE-Calculator is proposed. Pupils can dial numbers into appropriate columns, watching the gears work; place-value concepts are enhanced. Both activities and flowcharting are suggested. (MNS)

Presented are activities which give practice in making estimates, gathering data, and checking the reasonableness of results. (TG)
