A card game designed to help high school students drill basic arithmetic operations in general mathematics classes is presented. Activity sheets suitable for reproduction are included. (MP)

A tool to aid elementary calculus students in the computation of unusual limits is reviewed. (MP)

Teaching and learning mathematics in classrooms is interpreted as human interaction in an institutionalized setting. Using theories and categories from different disciplines, a classroom episode is reanalyzed. Four hidden dimensions in the classroom process and thus deficient areas of research are identified. Consequences for teacher training are…

The effects of two item formats on item difficulty and item discrimination indices for mathematics problem solving multiple-choice tests were investigated. One format required identifying the proper "set-up" for the item; the other format required complete solving of the item. (Author/JKS)

To illustrate what a young, self-taught computer enthusiast can accomplish, 11-year-old Safi Bahcall presents two BASIC computer programs he developed. The first converts numbers from one mathematical base to another. The second monitors commodity investments. In his introduction, Harold Nelson notes some of Safi's other computer achievements.…

The method used at airports in determining the cloud height at night is presented. Several problems, the equation used, and a simple design of an alidade (an instrument that shows cloud heights directly) are also included. (MP)

Ten high school geometry teachers were observed to determine if there was differential treatment of male and female students. A trend of higher quantity and quality contacts with male students was noted. (MP)

Several BASIC computer programs designed to illustrate concepts in probability are presented. The programs are geared for the Apple II computer, but most samples are adaptable to other systems. (MP)

Two responses to a prior report on significant figures and a discussion on outlining conventions for the accuracy of answers are included in this document. A clarification of the supposed error in the original report is noted at the beginning. (MP)

An organized series of steps designed to help students solve related rate problems often found in beginning calculus is presented. Two example problems are taken through five steps of solution. (MP)

The development of the new mathematics curriculum of the late 1950s is examined in light of current calls for changes in the instructional program. Thoughtful, imaginative reform that offers radically new models of approach to teaching mathematics is called for. (MP)

The need for students of engineering to acquire the rational, methodical approaches identified with the "mathematical way of thinking" is discussed. The skill areas in mathematics most critical to engineering majors are pointed out, with proper shaping of student attitudes seen as an important role secondary school mathematics must play.…

A study of student attitudes towards computers in a mathematics class found significantly positive relationships between such use and their attitudes towards mathematics, the instructional setting, achievement in mathematics and programing, and previous programing experience. No significant relationship between students' intelligence and attitudes…

A guided discovery lesson on the Law of Sines was analyzed for teaching moves. After breaking down the lessons in a transcription, the frequency of certain moves was listed and then categorized. This report is designed to serve as a guide to others who wish to make similar studies. (MP)

Five basic skill areas needing more attention in standard high school geometry are discussed. Levels of student mental development in geometry and a need for less emphasis on formal proofs are reviewed. (MP)
