Short essay questions are introduced into the calculus course as a technique to involve students with their own learning. Provides (1) instructions to the student for writing the report; (2) results of using the technique; and (3) reasons for using writing in mathematics classes. (MDH)

Working in groups on weekly themes, students discover calculus concepts through assigned readings and written reports. Provides an outline of the course content for two courses and how the courses are organized. An appendix contains the complete text of two themes on curve sketching and applications of the definite integral. (MDH)

Presents three teaching strategies requiring active student participation in which students (1) create and solve their own word problems; (2) generate trigonometric expressions to be solved by their classmates; and (3) act as points to model a basic locus of points. (MDH)

The first idea concerns a board game similar to tic-tac-toe in which the strategy involves the knowledge of the factorization of quadratic polynomials. The second game uses the calculation of the surface areas of solid figures applying the specific examples of cigar boxes and cylindrical tin cans. (JJK)

Described are the inexpensive construction and the suggested classroom applications of three different demonstration devices, as alternatives to the use of computer graphics, for displaying the conic sections. These devices are the simplified string model, the stroboscopic cone generator, and the capillary hyperbola. (JJK)

By incorporating writing into everyday math activities, elementary students become better communicators and learn to express themselves, mathematically and otherwise, with more confidence and clarity. An elementary teacher presents several successful writing activities from her math classroom, including a math word web, a guided-response sheet,…

Analysis of data on grade 11 students from the 1985-86 National Assessment of Educational Progress indicates that minority students are substantially disadvantaged in mathematics, and that students of all races score low enough to jeopardize future United States leadership in science and technology. (Author/MSE)

Provided are three program listings which may be used to illustrate this fractal figure. Extensions of these algorithms and their use in the study of chaos and fractals are suggested. (CW)

Presented is an activity designed to develop a concrete linear model to assist students in estimating answers to percentage problems and developing an understanding of the concept of percentage. (CW)

Reports research findings regarding the learning and teaching of proportional reasoning. Presents four tasks devised to assess students' proportional reasoning and describes four solution strategies for solving these tasks based on the analysis of seventh and eighth graders' correct responses. (MDH)

Examines aspects of language connections in the learning of mathematics in three sections that discuss the interaction between language, symbolism, and manipulatives; emphasis on context in language development; and language connections in problem solving. Presents implications for nonnative English speakers. (MDH)

This article explores the multiple representations (verbal, algebraic, graphical, and numerical) that can be used to study the golden ratio. Emphasis is placed on using technology (both calculators and computers) to investigate the algebraic, graphical, and numerical representations. (JAF)

Emphasizes a real-world-problem situation using sine law and cosine law. Angles of elevation from two tracking stations located in the plane of the equator determine height of a satellite. Calculators or computers can be used. (LDR)

This is a reprint of an address given at the Christmas National Council of Teachers of Mathematics (NCTM) meeting in 1958. It provides a critique of elementary instruction and discusses the changes necessary. It calls for fundamental change in the concept of mathematics teaching. (PDD)

Describes the benchmark and decomposition-recomposition estimation strategies and presents five techniques to develop students' estimation ability. Suggests situations involving quantities of candy and popcorn in which the teacher can model those strategies for the students. (MDH)
