An eight-step teaching guide to help elementary students become familiar with electronic calculators. (Author/SJL)

The author points out the usefulness of the ALP minicalculator program with learning disabled learners and introduces a novel aspect of the program--a new method of dealing with fractions via the calculator in which decimal answers are converted to equivalent fractions. (SBH)

Uses a graphing calculator to demonstrate that dividing by a fraction is the same as multiplying by the reciprocal. Students graph a division problem and an equivalent problem, multiplying by the reciprocal. They find that the graphs are the same. (SKS)

Describes an exploration involving parabolas that was prompted by a routine exercise undertaken in a graphing-calculator workshop with high school mathematics teachers. Appendices contain instructions for using the TI-85 SIMULT menu and matrices to solve the system. (JRH)

Discusses the behavior of functions under reciprocal mappings, focusing on the horizontal reciprocal transformation. Offers suggestions for using the graphing calculator, for extending the concepts, and for teaching about reciprocal mappings. (JRH)

Documents the experiences of 25 first-year university students with regard to the kinds of tasks calculus instructors should design in order to engage students in mathematical practices that often require the use of a graphing calculator. (MM)

Discusses planetary motion and universal gravitation using a graphing calculator. Includes program and data. (MKR)

Introduces the Sharp EL-9600 graphing calculator and its capabilities, and discusses its possible uses in mathematics classrooms. (ASK)

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."
