Analysis of the constraints and potential of the artefact are necessary in order to point out the mathematical knowledge involved in using calculators. Analyzes and categorizes observations of students using graphic and symbolic calculators into profiles, illustrating the transformation of the calculator into an efficient mathematical instrument.…

Reviews tasks and techniques to help students develop an appropriate instrumental genesis for algebra and functions to prepare for calculus. Focuses on the potential of the calculator to connect enactive representations and theoretical calculus. Discusses strategies to help students experiment with symbolic concepts in calculus. (Contains 32…

The difference between estimation (the mental skill of making an educated guess) and approximation (finding a result precise enough for a specific purpose) is discussed. (MNS)

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)

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)

Suggests the use of a calculator to scale photographs for the printer. (HOD)

Why calculators should be used for testing, as well as for instruction, is discussed. The focus of the curriculum would shift from computation to deeper development of concepts and to mathematical modeling. A broader curriculum would result. (MNS)

Drawing from experiences at Ohio State University (OSU) with remedial college students and with 12th grade students without elementary algebra skills, this paper outlines a numerical approach to algebra instruction using handheld calculators. Introductory material discusses problems with traditional approaches to math education and outlines some…

A game for the HP-25 programable calculator is discussed. The objectives of the game are to introduce angle measurement and the rudiments of trigonometry. A program for the game is given. (MP)

Described is the use of calculators in two experiments. In the first, students determine the relative atomic mass of magnesium. In the second, students use a calculator to determine a constant for gaseous concentrations of two reactants and the product at equilibrium. (AJ)

Use of calculators rather than computers or paper and pencil when calculators can do the job is stressed. When the use of calculators is more appropriate is indicated. (MNS)

Provides a rationale for using calculators to study large numbers in the elementary school. Suggests that calculators be used to encourage children to develop their interest in large numbers, to become more adventurous in their explorations of them, and to stimulate their curiosity in their occurrence. (JN)

The general algorithm used in most hand calculators to approximate elementary functions is discussed. Comments on tabular function values and on computer function evaluation are given first; then the CORDIC (Coordinate Rotation Digital Computer) scheme is described. (MNS)
