Explores the attitudes of a small group of primary teachers towards the use of calculators. Suggests low calculator use in these classes is often by default rather than because of an anti-calculator stance. (ASK)

Examines the relation between the sequence of approximations to the square root of a number and the harmonic, geometric, and arithmetic means using the TI-85 graphing calculator. (MKR)

Stresses the links between the technical work and the conceptual reflection in the learning of mathematics and argues that the potential of Computer Algebra Systems (CAS) is to be found in the more varied and richer techniques that CAS can offer. Reports on an experiment with DERIVE as well as findings of research on graphical calculators, and…

Explores some ideas for the imaginative use of a graphics calculator in introductory statistics teaching. (Author/ASK)

National Assessment of Educational Progress (NAEP) shows a deficiency in U.S. students' mathematics performance and computation skills. The students using calculators in school classrooms result in lower math scores than students who never use them.

An intuitive derivation of Stirling's formula is presented, together with a modification that greatly improves its accuracy. The derivation is based on the closed form evaluation of the gamma function at an integer plus one-half. The modification is easily implemented on a hand-held calculator and often triples the number of significant digits…

This article describes a solution, using CAS, to graph theory problem that was presented in the movie "Good Will Hunting."

Graphing calculators and data collection technology was integrated in an undergraduate science methods classes for preservice elementary school teachers. The study investigated whether preservice teachers' knowledge and comfort with the use of graphing calculator technology and their perspectives in the use of graphing calculator technology were…

For mathematics teachers who are continually looking for ways in which to engage their students in the learning process, the capabilities offered by technology answer the call. Whether the technology comprises computer based applications or graphics calculators, often boring aspects can be bypassed so that students can work on the "good…

Describes a study in which fifth-graders learned how to operate electronic calculators and used them on a mathematics achievement test. The results indicated that the children with calculators outperformed the control children on the straight computational problems but did more poorly than the controls on thought problems. (JMB)

Five activities are presented in this student workbook on using the electronic calculator. Following the directions for using the machine, problems are given on multiplying and dividing, finding percentages, calculating the area of assorted polygons, changing fractions to decimals, and finding squares and square roots. (JH)

Students in three mathematics classes were assessed on two aptitudes, field independence and general reasoning, and randomly assigned to either an expository or a discovery treatment. The expository treatment used a deductive sequence of instruction and provided maximal guidance for the students. The discovery group used an inductive sequence with…

Illustrated is the use of pocket calculators for solving the Francis formula for rectangular, triangular, and V-notched weirs. (CS)

The calculator is used to determine the formula for computing annual yield from a savings account. (MP)
