Pretraining on test-taking strategies improved the reliability and predictive power of the Arithmetic Reasoning Test for seventh-grade Chicano students but not for non-Chicano students. Pretraining did not improve the reliability of the Missing Words Test for either group, but appears to have improved the predictive power of this test for both…

Transformations are defined and described through many examples. Teaching aids and activities for teaching about transformations are suggested. (JT)

The authors describe a series of magic tricks based on computation which they use in elementary and secondary school mathematics classes to motivate and challenge students. (SD)

Indicates that only 21% of respondents (secondary school math teachers) used computer-assisted instruction for tutorial work, physical models to interpret abstract concepts, or real-life application of the arithmetic or algebraic manipulation. Recommends that creative teaching methods be applied to problem solving. (NKA)

Presented are the mathematical explanation of the algorithm for representing rational numbers in base two, paper-and-pencil methods for producing the representation, some patterns in these representations, and pseudocode for computer programs to explore these patterns. (MNS)

A brief overview is given of a research project funded to investigate the cause and cure of errors in ratio and proportion, algebra, and fractions. Choosing pertinent information, interviewing students, listing significant features, developing lessons, and testing the materials are considered. (MNS)

Developing assessment measures so that the ratings for assignments across teachers will be similar was the goal. What was learned from testing and how valid and relevant assignments might be produced and recognized are described. Survey results are included. MNS)

Reports on a study into the problem solving abilities of students in a Jamaican high school who were intentionally taught problem solving strategies during one-sixth of their mathematics instruction for one academic year. Results indicated no significant increases in their performance on a problem solving test. (TW)

Considers the problem of constructing Venn diagrams for more than three sets. Presents an unusual geometric display of a Venn diagram for five sets. (PK)

Reports that students frequently confuse meanings of terms and misunderstand function-related concepts. Also, providing mental images of functions is often limited to elementary algebra examples. This article describes a game which can help create conceptual links between the function properties and their various representations. (PK)

The aim of this article is to provide a conceptual picture of a "Mathematics and Society" curriculum. Examples of such curricula are described, along with discussion of ethnomathematics and self-generated mathematics, the social institution of mathematics, critical thinking and conscientization, and policy issues. (MNS)

Explains a unified approach to using the computer as a teaching tool for helping students discover concepts and principles involved in geometry. Describes the Geometric Supposer series which allows students to develop constructions and measure angles, areas, and circumferences. States that supplemental materials are also available. (RT)

Presents results of an investigation of a formula for rank correlation. The exploration turned up an unexpected connection and showed the formula to be far from arbitrary. (PK)

Description of the field of robotics and its possible use in high school computational geometry classes emphasizes motion planning exercises and computer graphics displays. Eleven geometrical problems based on robotics are presented along with the correct solutions and explanations. (LRW)

This article gives a brief account of secondary school mathematics curriculum development in China. Some experimental teaching materials and teaching methods are introduced. One of the most influential projects is described in detail. (Author/PK)
