In this article, the author focuses on possible ways to develop the concepts of joint variation and function through the upper primary and lower secondary years of education. The examples demonstrate the building of a range of important mathematical ideas by modelling life-related situations using students' informal and intuitive knowledge. Over…

Illustrates the ease with which programs occupying only a single command line of a graphics calculator can be constructed. (MKR)

This reprinted article from the November 1976 issue of "Arithmetic Teacher" describes a series of calculator games suitable for all levels from kindergarten through calculus.

This paper reports on a study of 22 preservice teachers enrolled in a first-semester mathematics teaching methods course. Course activities included participation in two separate field experiences in neighboring school districts. The methods class placed considerable emphasis on the use of advanced digital technologies in the teaching and learning…

Explores various emerging technologies for use in the teaching and learning of mathematics and science. Discusses advanced graphing calculators, networked calculators, and participatory simulations. (MM)

This essay begins with a brief history of calculator development and presents some lessons learned about using calculators in work dating back to the 1970s. A position statement on the appropriate use of calculator technology is presented along with a discussion of some of the controversial issues that have arisen as a consequence of the use of…

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)

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)

This paper was developed with the goal of enhancing the mathematical preparation of secondary school teachers in the technological paradigm. It shows how two-variable inequalities can be utilized as models for the construction of geometric objects using the software Graphing Calculator 3.5 (produced by Pacific Tech) as a relation grapher. An…

Computer Algebra Systems (CAS) can be used to help understand the behavior of cubics and other families of curves. The analysis of the parameters associated with a family of curves can give insight into the behavior of the family and can be used within the context of a mathematical model to determine a policy for the implementation of the model in…

This study investigated the effects of using the TI-92+ calculator to demonstrate geometric diagrams to students in class. The participants (N=83) were from three 10th grade classes. A pretest, treatment, posttest with control group design was used in the study. The treatments lasted for 12 weeks. Results from data analyses via the Dependent…

Examines what students think about calculators and their use in school by utilizing a short questionnaire. Concludes that children had mainly positive views about the calculator although much of it still remained a mystery, and none of them appeared particularly confident in using it. (ASK)

Discusses the appropriateness of lower secondary school students using graphics calculators instead of scientific calculators. (ASK)
