The impact and role of social needs, including computer technology, on the secondary school mathematics curriculum are considered. Their role in the American curriculum, mathematical applications, institutionalized needs, and alternatives are discussed. (MNS)

Many drugs are used up by the body at rates described in terms of exponential decay. Two simple exponential formulas are discussed. (MNS)

The teaching objectives and curriculum content of the secondary school mathematics program in China are discussed. Public examination papers and classroom teaching methods are described, with specific examples. (MNS)

One schools' experiences with mathematics contests are described, with American Pi, the Great Calculator Contest, and the Forest View Math Olympics in problem solving each detailed. (MNS)

The mathematical content involved in self-teaching enrichment models for students in grades 8-12, the pedagogy employed in a summer institute for such students, and the results obtained are presented. (MNS)

This review of research on secondary school geometry is drawn from the NCTM publication, "Classroom Ideas from Research on Secondary School Mathematics." Considered are the following topics: goals, content, time, textbook use, activity-oriented instruction, teacher communication, homework, student characteristics, proof, problem solving,…

Computer science may foreshadow some near revolutions in school mathematics, concerning new ways of teaching much of the mathematics curriculum, increased emphasis on discrete mathematics, and the impact of symbolic mathematical systems. Each is discussed, with a distinction made between computer science and computer technology. (MNS)

Provides domino geometry problems, problems with arithmetic progressions, and magic pentagram sums. (JM)

Explored the effects of microcomputer instruction organization on three variables: (1) sex of student; (2) social arrangement of classroom; and (3) curricular presentation (high and low guidance) for algebra I (N=114) students at a suburban high school. Learning was significant regardless of treatment, but behavioral changes were different under…

An example of how geometry serves as a model in the real world is outlined, with suggestions on how it might be used at the high school level. (MNS)

Stressed is a conceptual approach to absolute value, based on the visualization of the graphs of absolute-value equations. An important by-product is predicting a graph on the basis of certain constraints. Four worksheets plus teacher comments are included. (MNS)

This is a report of an application of the interpretation of errors and springboards in a real-life situation. If and why we need to reduce fractions is considered. (MNS)

A common mistake in adding fractions involves the confusion betwen the concepts of fraction and ratio. A coherent system to operate with ratios is developed. (MNS)

Several intuitive proofs for evaluating specific infinite expressions are given. Observations on intuition and errors in mathematics are included. (MNS)

Presents a set of classroom activities and a computer program that have been used to help students intuitively grasp, in a minimum of instructional time, such fundamental concepts as hypothesis testing, random sampling, statistical inference and p-values. The lesson shows students how statistical thinking and microcomputers can be used in…
