Factors influencing academic achievement in a school or school system were examined, using data from studies of mathematics and science achievement of high school and college bound students in Australia. Two curricular factors, opportunity to learn and time spent in learning, were related to achievement. (GDC)

The article includes a brief description of the project "Reckoning with Mathematics." The project is grounded in the belief that reliance in American schools on "textbook as technology" is outdated and counterproductive. A sample student worksheet is included. (PK)

Presents a practical application of mathematics that would be appropriate for a general liberal arts classroom exercise to illustrate how calculators and computers are important tools for the consumer. (PK)

Contains an update of an earlier listing of software for mathematics instruction at the college level. Topics are: advanced mathematics, algebra, calculus, differential equations, discrete mathematics, equation solving, general mathematics, geometry, linear and matrix algebra, logic, statistics and probability, and trigonometry. (PK)

The author addresses two types of classroom activities: strategic games and games of conflict. It is suggested that each has an important role to play in many areas of mathematics. In addition to providing examples of games, the author reflects on the processes involved in using the activities. (PK)

Described is the process approach to mathematics which is gaining momentum in primary schools. Included is a discussion of the origin and features of the movement and possible future directions and consequences of its growth. (PK)

The concept of variable is central to mathematics teaching and learning in junior and senior high schools. Described is a structured reflexive exercise designed to reexamine the notion of variable and to rediscover its richness and multiplicity of meaning. (PK)

Provides an overview of research relative to achievement in the area of similarity. Suggests activities which might improve student understanding of the concept. (PK)

Reports on a study designed to document that learning-disabled (LD) students make errors in estimating the passage of short time durations, and to determine if LD students were different than nondisabled in time estimation. Non-LD and LD students differed significantly in estimations of 15-second intervals, but not 3-second intervals. (PK)

Argues that "appropriate practical work" in mathematics aids understanding. Presents ideas and activities for teaching mechanics. Discusses modelling, problem formulation, and interpretation. (PK)

The aim of this article is to show some of the aspects of mathematics which lie within the arts, in particular the conflicts and emotions involved in the teaching and learning of mathematics. (PK)

Presented is an example that allows students to investigate trigonometric ideas in a simple and practical way. (PK)

Discusses computer methods for finding roots of polynomials. The program provided finds rational roots and prints the roots as rational numbers. (PK)

Discusses the status of the testing of computational estimation. Suggests ideas to promote needed immediate actions and examines issues related to effective assessment of computational estimation. (PK)

Suggests a series of ratio activities that make use of a computer to produce graphical collections of objects in a grid with variable dimensions. Extends content to the areas of proportions, statistics, probability, programming, and problem solving. (PK)
