A teacher describes the experiences of her fourth-grade students when using calculators during mathematics class. (MK)

The results of a school district's move to proficiency testing in mathematics are described and discussed. (MK)

This annotated bibliography includes activities with calculators in the areas of computational skills, geometry, measurement, number pattern recognition, and probability. (MK)

Communication of mathematical structure from curriculum developers to teachers and then to classes of secondary students was investigated. A high correspondence among the cognitive structure of curriculum developers, content structure, and teachers' cognitive structures, and between cognitive structure of a class and that of its particular…

The theories of Karl Popper, Imre Lakatos, and Jean Piaget are examined in an attempt to find answers to some long-standing, critical problems in mathematics education. (MK)

A description of a calculator project conducted in Indianapolis schools is given. Results include a positive change in teacher attitude toward calculator use. (MK)

Tessellation provides challenging problems for both the mathematician and the artist. This note presents some attempts to work in the borderland between art and science, using colored illustrations rather than long verbal explanations to demonstrate the progress achieved. (Author/MK)

A census-taking activity that can be conducted by elementary students is described. Sample data sheets and report forms are included. (MK)

The possibility of improving problem-solving performance and increasing interest in mathematics by incorporating calculators in the mathematics curriculum was investigated. Results indicate that teachers can experiment with calculators in the classroom without fear of endangering computational skills and a thoughtful program integrating…

Calculator-based activities are presented that may be used as the framework for a unit to replace much of the usual algebra material on exponential functions and logarithms. (MP)

The results of this study show no evidence of a decline in mathematics learning in elementary school classes that used calculators and suggested that primary students may benefit from using calculators. (MP)

An appeal is made for a more formal treatment of the topics of estimation and reasonableness of answers in the school mathematics curriculum. (MP)

Various classroom uses of simulation of random phenomena with a table of random digits are described. Examples are given to illustrate the mathematics of simulation. (MP)

A description is given of a teacher's technique for teaching mathematics to mixed-ability groups. Examples from two lessons are given. (MK)

Compares the relative difficulty of four types of word problems. Other variables considered are grade level, sex, order of testing, and performance on a computational skills test. (MK)
