A proposal to shift to a conceptually oriented curriculum using the calculator as an instructional tool and to eliminate the teaching of complex computations in elementary school is presented. (MP)

Changes in the elementary and junior high school mathematics curriculum that have occurred in the last 20 years and that may occur in the future are discussed. (MK)

This essay discusses the possible types of uses of calculators in the elementary school, citing several publications, articles, and research studies. (MP)

Two units of study are given here for teaching elementary school students the use of the programable calculator. Storage registers and the program memory are considered. (MP)

Raises and responds to questions about what and how to teach mathematics with the availability of calculators to all students. Discusses whether students need basic facts, mechanical skills, and knowledge of computational algorithms. Argues that students need to develop number sense and analytical skills using simple, symbolic, and graphing…

Describes a study designing and implementing technology-based investigations and evaluates their impact on student learning. Discusses a teacher's mediation of the students' use of technology through curriculum materials, and considers some attributes of computers and graphics calculators that determined which tool was selected for each…

In this brief review, research on varying types of instructional materials is summarized. The evidence indicates that the textbook is the most widely used instructional material, and few teachers appear to use any other materials more than five times a year. Research findings on the value of the use of manipulative materials seems clear: they have…

A problem-solving program supplemented by calculators in one treatment group was conducted in 63 grade 7 classes with about 1350 students. Teachers were provided with problems correlated with textbooks, and instruction for teaching problem-solving strategies. School districts provided calculators and problem-solving materials. Pretest scores…

This study was designed to investigate the effectiveness of a heuristic approach to problem-solving instruction. The 330 subjects were randomly assigned to either a Problem Solving, Calculator Problem Solving, or Control group. The two experimental groups studied problem-solving heuristics applied to nonroutine problems for 18 weeks, after which…

This report discusses some of the activities of the Iowa Problem-Solving Project (IPSP). The document has three main sections: (1) Materials Development, where IPSP teaching materials and test development are discussed; (2) Summative Evaluation of Materials, presenting the procedures, results, and findings of the 1978-79 evaluations; and (3)…

The twenty-two essays on problem solving included in this publication give ideas and examples for use in the classroom at all levels of instruction. Topics discussed in the essays include but are not limited to: problem posing, clues from research, story problems, calculators, textbook problems, and measuring problem solving. Polya's heuristics as…

The first aim in school might be to help children become more aware of the algorithmic processes they use; then, ensure that they can devise algorithms and define them. Many examples of how these aims can be met are given, including the use of calculators and computers. (MNS)

The author discusses changes in the mathematics curriculum enabled by the use of calculators and computers. The need to eliminate long division and change how we teach other mathematical concepts is stressed. (MNS)

Results of a study conducted to gather information about calculator usage in Missouri schools are given. (MK)

The study concluded that ninth-grade Fundamentals of Mathematics students can achieve at a higher level when using hand-held calculators and a specially designed curriculum. (MK)
