This paper outlines an experiment in which pupils in Key Stage 2 were encouraged to use graphics calculators, in particular two simple programs, which helped them develop recall of their tables and allowed them to practise multiplication. The pupils responded very well to the calculators and seemed to have been motivated by them. The pupils did…

Inquires into assessment items classified as "extended pieces of work" in applicable mathematics in Western Australia. Identifies opportunities for graphics calculator use in extended pieces implemented in schools. Concludes that availability of the technology has widened the scope of approaches used in extended pieces of work in…

This study analyses some of the consequences of adopting a functional/modelling approach to the teaching of algebra. The teaching of one class of 17 students was observed over five weeks, with 15 students undertaking both pre- and post-tests and 6 students and the teacher being interviewed individually. Use of graphics calculators made the…

In this article, the authors describe how to use a TI-73/83/84 graphing calculator and Vernier's LabPro/CBL2 probe system to take pH readings. This is not an endorsement of these products, but simply the authors' attempt to give readers an idea of what is involved in using this technology in the classroom. This activity can be accomplished using a…

The chain rule is one of the hardest ideas to convey to students in Calculus I. It is difficult to motivate, so that most students do not really see where it comes from; it is difficult to express in symbols even after it is developed; and it is awkward to put it into words, so that many students can not remember it and so can not apply it…

The purpose of this study was to evaluate the effectiveness of a mathematics enrichment activity used to improve the mathematics performance of students relative to participation in the State Agricultural Mechanics Career Development Event (CDE) and in mandated assessments. The treatment group (13 schools, 43 students) participated in a…

Assumptions: In mathematics learning, one of the considerations in the graphing calculator (GC) use is to understand students' attitude toward calculators. Rationale: This presentation describes design of an assessment instrument of students' attitude toward graphing calculator. Objectives: A pilot study that assessed the effectiveness of the…

Although the nature of the research varies, as do concepts of angle, research in general supports the supposition that angle is a complex idea, best understood from a variety of perspectives. In fact, the concept of angle tends to be threefold, consisting of: (1) the traditional, static notion of two rays meeting at a common vertex; (2) the idea…

Graphing calculators and data collection technology was integrated in an undergraduate science methods classes for preservice elementary school teachers. The study investigated whether preservice teachers' knowledge and comfort with the use of graphing calculator technology and their perspectives in the use of graphing calculator technology were…

This article illustrates the fact that unless tempered by algebraic reasoning, a graphing calculator can lead one to erroneous conclusions. It also demonstrates that some problems can be solved by combining technology with algebra.

This document is a collection of lesson plans written by 18 of Ohio's outstanding teachers chosen by the Ohio Council of Teachers of Mathematics. Each lesson plan includes reflection questions and some contain worksheets. Lesson plan titles for primary grades (grades 1-3) are: "Munching Fractions;""Math and…

This booklet contains a representative sample of the efforts of colleagues at 11 institutions to use graphing calculators to enhance the teaching of calculus and precalculus. The first section contains examples of graphs for teachers to choose from for presentations, including: simple examples to illustrate some standard ideas in precalculus,…

This paper reports on a workshop developed to give middle school teachers experience using the TI-73 calculator as a teaching tool and to serve as a model for the introduction of technology into their classrooms. A booklet prepared for the workshop gave keystrokes used for the TI-73 with an emphasis on features that are unique to this calculator.…

How does your calculator quickly produce values of trigonometric functions? You might be surprised to learn that it does not use series or polynomial approximations, but rather the so-called CORDIC method. This paper will focus on the geometry of the CORDIC method, as originally developed by Volder in 1959. This algorithm is a wonderful…

This essay describes the role of graphing calculators in mathematics reform. Among the topics discussed are the history of graphing calculators in mathematics education, recent technological innovations, and professional development opportunities. The case is made for a balanced approach between calculator use and paper-and-pencil techniques.…
