Guin, Dominique; Trouche, Luc – International Journal of Computers for Mathematical Learning, 1998
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.…

LaGrange, Jean-Baptiste – International Journal of Computers for Mathematical Learning, 1999
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…

Masat, Francis E. – 1994
Graphing calculator use is often thought of in terms of pre-calculus or continuous topics in mathematics. This paper contains examples and activities that demonstrate useful, interesting, and easy ways to use a graphing calculator with discrete topics. Examples are given for each of the following topics: functions, mathematical induction and…

Hall, Lucien T., Jr. – Mathematics Teacher, 1984
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)

Block, Gerald H. – Academic Therapy, 1980
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)

Pelech, James; Parker, Jacquelyn – Mathematics Teacher, 1996
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)

Houssart, Jenny – Micromath, 2000
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)

Heid, M. Kathleen – Mathematics Teacher, 1988
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)

Leitzel, Joan R. – 1984
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…
