This paper reports on the experiences of students who were learning mathematics with CAS for a second consecutive school year. Evidence presented shows that nearly all students managed the challenging task of mastering the technical aspects of using CAS well. It also shows that the level of technical difficulty and the degree to which it presents…

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.

Ongoing professional development programs are required by teachers in order to become more effective in teaching. Although, in-service courses are offered to enhance the teachers' professional skills but the courses are not relevant to their needs. This may be due to the administrators' assumptions of the teachers' needs rather than what the…

Building physical models relative to a concept can be an important activity to help students develop and manipulate abstract ideas and mental models that often prove difficult to grasp. One such concept is "time". A method for helping students understand the cyclical nature of time involves the construction of a Time Zone Calculator through a…

The velocity of sound in a gas depends on its temperature, molar mass, and [lambda] = C[subscript p]/C[subscript v], ratio (heat capacity at a constant pressure to heat capacity at constant volume). The [lambda] values for air, oxygen, nitrogen, argon, and carbon dioxide were determined by measuring the velocity of the sound through the gases at…

Little is known about how best to teach mathematics to students with learning disabilities. This study explored the performance and self-reported calculator use of 13 sixth-grade and 15 seventh-grade students with learning disabilities educated in either standards-based or traditional mathematics curricula on multiple-choice and open-ended…

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…

Discusses the use of calculators as a way of helping people to develop basic math skills. Suggests using calculators to check answers, to perform calculations rather than working them out on paper, and as a tool to accelerate learning. (JOW)

Covers a project conducted by the Freudenthal Institute in which observation of student behavior supported the premise that the graphics calculator can stimulate the use of realistic contexts, the exploratory approach to mathematics, a more integrated view of mathematics, and more flexible behavior in problem solving. (AIM)

This paper extends the discussion of the critical line approach using three risky stocks as described in Haugen's Modern Investment Theory, 4th edition. A dynamic presentation of the concepts involved in finding the efficient set, using two EXCEL spreadsheets and an HP-12C hand-held calculator, is provided. This dynamic presentation will enable…

Describes the use of programmable calculators in a linear algebra course at the University of Kansas. Reports that these calculators can exploit the opportunities of personal computing and allow students to concentrate on how to apply new mathematical principles to real-world applications. (JRH)

Examines ways in which students can learn about computational discrepancies that arise as a result of a calculator's limited ability to store numbers accurately. Suggests ways in which such discrepancies can be avoided. (Author/NB)

In order to stimulate further discussion, this article addresses issues concerning calculator use in elementary school mathematics such as: Is computation still important in elementary school? How would a calculator-driven curriculum look? When is calculator use appropriate? and How should calculators be used? (Author/MKR)

Not all educators agree that the best ways to teach mathematics include giving students electronic calculators. But many do, and their view is reflected in the policies and practices of school districts, textbook publishers, testing companies, and state education agencies. That adds up to profits for Texas Instruments Inc., the Dallas-based…

The beliefs of preservice elementary-school teachers regarding the use of basic calculators and "Illuminations" activities were investigated. The goals of the study were to describe preservice teachers' beliefs, identify the sources of those beliefs, and determine which interventions successfully modify them. Participants included 210…
