Timing stoplights and trying to determine the best way to allocate cycle time to the two directions is discussed. The simple case and improving the model are both considered. (MNS)

This article was written in part to celebrate the anniversaries of landmark mathematical works by Newton and Descartes. It's other purpose is to dispel some myths about Sir Isaac Newton and to encourage readers to read Newton's works. (PK)

Described is a series of five related microcomputer-based laboratory analysis programs that are used by students in a college calculus-based physics course. With minor modifications these programs, which are written in BASIC, could be used in most beginning undergraduate laboratory science courses. (RH)

A slight rewording can often transform a routine exercise into a nonroutine one. Three problems (with solutions) from first-year college calculus are presented to illustrate how the technique can be used and how it is applicable to any course. (JN)

Investigated were the effects of spatial training on calculus achievement, spatial visualization ability, and the use of visualization in solving problems on solids of revolution. Sex differences were found favoring women in calculus achievement and men in spatial visualization ability. (MNS)

Discusses a computer calculus game which follows the path of a parabola in stepwise progression. The educational value of the game is a simple example of nonlinearity, a subject which is just beginning to earn some attention in the mathematical community. The Applesoft program listing is included. (JN)

Newton's method for finding roots of equations is described. How to find complex roots using the BASIC computer language is then presented, with the computer program included. (MNS)

Extracts from booklets providing critical reviews of and recommendations related to textbooks of the Nuffield Mathematics Project are presented. (SD)

An approach to absolute value is described which emphasizes the metric property of the absolute value function and the fact that the real number form an ordered set. (DT)

Author states that the use of computers in mathematics courses tends to generate interest in course subject matter and make learning a less passive experience. Computers also introduce students to computer science as a field of study, and provide basic knowledge of computers as an important aspect of today's technology. (Author/RW)

In two previous studies we investigated the non-routine problem-solving abilities of students just finishing their first year of a traditionally taught calculus sequence. This paper reports on a similar study, using the same non-routine first-year differential calculus problems, with students who had completed one and one-half years of traditional…

This paper reports ongoing research investigating how students' experiences with the notion of tangent line in different lecture courses at a technical school are being integrated to the related mathematical concept. Focusing on a technical course case study, we examine how aspects of the notion of tangent line are related to features of the…

This study examined quantitatively the effects of varying retention intervals (RI) within a 4 X 4 block schedule on knowledge retention of Algebra 2 skills and concepts. Specifically, the study contrasted the mean scores of students having an RI of 0, 8, and 12 months on a pre-review, post-review, and end-of-course test in precalculus. The study…

This document describes a two-year project designed to prepare, desk-top publish, and class-test supplemental materials geared specifically toward a slower-paced, one-year Calculus I course that integrates the review of precalculus topics as they are needed. This course replaces the traditional two-semester Precalculus-Calculus I sequence for…

This paper describes a model for effective incorporation of technology into the learning experience of a large and diverse group of students in first-semester first-year tertiary mathematics. It describes the introduction of elementary use of MATLAB, in a course offered both on-campus and at a distance. The diversity of the student group is…
