Reviews the use of handheld computers and mobile imaging devices for teaching and learning. Highlights include features of handheld computers to consider for use in elementary and secondary education; graphic calculators as part of local area networks; digital cameras; and portable scanners. (LRW)

Describes the use of an application for TI-83 and TI-92 calculators called the Symbolic Math Guide (SMG) for teaching and learning the laws of exponents in algebra. Discusses ways in which the SMG can be used for teaching, review, and testing. (MM)

Introduces the notion of a class networked with graphing calculators and discusses the pedagogical implications of this set up. New teaching methods are necessary to exploit the potential of the system. (MM)

Shares experiences of a project aimed at developing and refining programs written on a Casio FX9750G graphing calculator. Describes in detail some programs used to develop mental strategies and problem solving skills. (MM)

Provides a lesson plan designed to form three one-hour sessions with mixed ability groups of 11-12 year olds. The activity involves students estimating road distances by counting the number of map grid lines crossed in going from A to B. The activity is designed to introduce students to graphing calculators. Screenshots from the calculator are…

Describes the different types of scientific calculators and explains how graphic calculators can apply to chemical problems. (Contains 19 references.) (YDS)

This article reports on results of an exploratory study on undergraduate pre-service teachers' understanding of graphical representations of motion functions. The study described pre-service teachers' explorations using a CBR device. Pre-service teachers' growth was studied in two dimensions: (a) in their learning of the mathematics involved and…

Probably the one "new" mathematical topic that is most responsible for modernizing courses in college algebra and precalculus over the last few years is the idea of fitting a function to a set of data in the sense of a least squares fit. Whether it be simple linear regression or nonlinear regression, this topic opens the door to applying the…

A Mandelbrot mathematical set is an object with endless borders, and in the present exercise a graphing calculator is used to identify and examine the set points. The significance and power of technology is also displayed in the understanding and solving of problems.

A teacher shares his successful experience in helping students understand the relationship between exponents and logarithms in high school and college courses. He presents the procedure that he used for teaching using a graphing calculator that shows previous calculations made.

A demonstration, which shows that the graphing calculation can greatly supplement the computer and often eliminates the need for computers and science, is given. The graphic calculator is a handheld computer, more powerful than most sophisticated computer of 25 years ago.

Discusses a real-world problem-solving lesson that emerged when a high school math teacher used a motion detector with a CBL and graphing calculator to obtain the bounce data of a ping-pong ball. Describes the lesson in which students collect bad data then fill in the missing parabolas that result using critical components of parabolas and…

The purpose of this study was to determine if the use of a graphical teaching and learning approach via the graphing calculator enhances students' understanding of the formal definition of limit. College students in six sections of Calculus I participated by completing a test prior to the introduction of the definition, and completing a second…

Technologies play a prominent role in current reforms of school and collegiate mathematics. This study examined ways in which first-semester calculus students still showed the influence of a graphing-intensive college algebra course they had studied one or two semesters earlier. Students (n=18) at a large research university were asked to solve a…

The study of linear functions is important as it provides students with their first experience of identifying and interpreting the relationship between two dependent variables. This paper, which builds on previous research, reports a study undertaken with 64 year 9 students from two Australian schools. Linear functions were introduced to these…
