Describes the desk top calculators now on the market, including manufacturers, prices, and functions performed. Provides a table of specifications for programmable desk calculators. (MLH)

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)

Briefly traces the development of computers from the abacus, John Napier's logarithms, the first computer/calculator (known as the Differential Engine), the first computer programming via steel punched cards, the electrical analog computer, electronic digital computer, and the transistor to the microchip of today's computers. (MBR)

An evaluation of five voice calculators now on the market--the Canon SP-1260-D, Panasonic JE-165OU and JE-72OU, Sharp EL-620, and Speech Plus--by 20 legally blind adults indicated that most can easily by used by visually handicapped people. Descriptive information is given. (Author/MC)

An approach to the teaching of business mathematics with the use of the electronic calculator. (Editor)

Presents the results of an investigation into how pre-service teachers with low-level mathematics qualifications do mathematics when using hand-held, sophisticated mathematics technology as a tool. Results indicate that students were able to master the technical aspects of the TI-92, ask relevant questions and engage in mathematical discussion,…

Explores the myths surrounding the use of calculators in primary school. (Author/CCM)

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)

Questions the effectiveness of graphics calculators in developing mathematical understanding. Investigates how a small group of students actually used graphics calculators in examination conditions. Finds that very little was made of the calculator when taking the exam with most students preferring to use a scientific calculator instead unless a…

This article describes a hands-on activity that explore weaving patterns of the Tellem people. It includes a graphing calculator program that simulates the weaving pattern.

Describes the results of a teacher's exploration of the effects of using graphing calculators in calculus instruction in sections other than those that are experimental. Two experimental and two traditional sections of Calculus I and II participated in the study. (DDR)

This book is part of the "Windows on Literacy: Language, Literacy & Vocabulary" program and shows students ways to solve problems, including drawing a picture and using a calculator. The suggested grade range is K-3; the guided reading level is N-P; the basal results level is Grade 2-Grade 3; and the Windows on Literacy Stage is Fluent Plus…

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.

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…
