A program designed to tutor algebra students in inequalities is presented. The program is designed around the graphics of the Apple II computer, and randomly picks graphs, and shades inequalities. (MP)

A program designed in the BASIC programing language to provide drill and practice with positive and negative numbers is presented. (MP)

This section focuses on finding two-dimensional geometric shapes in designs and three-dimensional objects. The material is presented on worksheets designed for duplication for classroom use. (MP)

Using three sets of real data, a comparison of four discrete discriminate analysis procedures is made using the actual versus the optimal error rate. The kernel method gives the most accurate results in all three cases. (Author/RL)

Three questions dealing with hypothesis testing are presented. Activities that can be best worked with calculators as tools are detailed and suggestions for extensions of these problems are given. (MP)

A mathematical treatment of the relationship between driving speed and fuel efficiency is presented. The material involves applications of exponentials, logarithms, and elementary calculus, and is intended to be enrichment material for secondary and lower college mathematics classes. (MP)

An activity unit designed to help students discover some of the patterns of sine and cosine functions is presented. Worksheets designed for duplication are included. (MP)

A unique problem solving activity involving student lockers in a junior high school is presented. The activity embodies numerous mathematical concepts and has successfully motivated pupils to explore related mathematical ideas. (MP)

Three teaching ideas are discussed: the improvement of ditto reproduction, and exploration of congruent triangles, and an intuitive introduction to the concept of limit. (MP)

An exercise in applied mathematics that focuses on belt drives that is suitable for senior secondary pupils is presented. Some comments on classroom use and student reactions to this lesson are included. (MP)

A lesson for secondary mathematics pupils on prime numbers designed to capture student interest is presented. The emphasis is on developing lessons that act as motivating forces in the classroom. (MP)

This article reports a field evaluation of experimental first-year algebra materials, "Algebra Through Applications." Effectiveness of the materials was evaluated in terms of achievement, attitude, transfer to consumer, problem solving, readability, and implementation. Overall, it was found the experimental materials could be used…

The purpose of this study was to identify which of 36 mathematical competencies were deemed desirable or mandatory by hiring officials in selected businesses. (MP)

Results of an investigation of numeracy skills of first-year London Transport craft apprentices are reported. (MP)

The author discusses problems with available mathematics textbooks and suggests that a computer "problem bank" is a viable alternative to a textbook. (MK)
