Offers examples of loss of accuracy when using digital computing devices. Discusses causes for loss of accuracy and methods of preventing loss. Presents implications that loss of accuracy has for mathematics instruction. (MDH)

An analysis was made of the use of computing tools at the graduate and undergraduate levels in colleges and universities in the United States. Topics ranged from hand-held calculators to the use of main-frame computers and the assessment of the SPSSX, SPSS, LINDO, and MINITAB computer software packages. Hand-held calculators are being increasingly…

Presented are several suggestions for teaching elementary school mathematics with technology. Activities use calculators and microcomputers for teaching multiples. (RH)

Presents two elementary level activities designed to make math more meaningful with the help of technology. One activity involves learning about banking using computer spreadsheets and stock programs; the other uses computers and calculators to help students integrate mathematics into the study of world cultures. (SM)

This booklet is intended to acquaint educational policy-makers with some of the current roles and potential applications of computers in the curriculum, and to encourage them to initiate actions that will lead to proper and effective instructional use of computers in school systems. It is organized as a series of questions and answers designed to…

In three parts, this booklet provides elementary teachers with definitions of essential computer terminology and examines instructional uses of computers and computer-related activities. Terms defined are computer, interactive computing, computer hardware, computer software, and programming languages. Part 2 explores the main categories of the…

Summarizes a series of handbooks, "Mathematics in ILEA Primary Schools," for helping teachers (Inner London Education Authority). "Children and Mathematics" provides a framework for classroom content and suggestions for activities. "Making It Happen" is intended to help coordinators. "Starters" describes…

Computer spreadsheets, computer graphing software, and programable graphing calculators are each demonstrated in the computational process of numerical iteration as a problem-solving method. Examples, illustrations, practical tips, and a typical calculator program are included. (JJK)

Utilizes a computer-generated graph to solve an equation for methods using trigonometric tables or less sophisticated calculators would likely fail because of round-off errors and limitations of the instruments. Discusses how this new technology can be utilized in mathematics instruction. (MDH)

Presents several problems that use calculator or computer-generated graphs of the absolute value function as related to the maximum and minimum functions to illustrate the statistical concepts of range, median, mean, and variance. (MDH)

This Texas Tech University computer literacy course designed for preservice elementary and middle school mathematics teachers lacking a technological orientation facilitates their computer introduction through preliminary use of calculators. Course development, philosophy, and course segments are outlined with emphasis on the sequence in which…

Two trigonometry problems are presented. The first compares the graphs of the functions arcsin[sin(x)], arccos[cos(x)], and the identity function f(x)=x. The second, using the law of cosines, demonstrates that the solution of a triangle knowing two sides and the excluded angle is no longer ambiguous. (MDH)

Presents an algorithm to estimate pi by approximating a unit circle with a sequence of inscribed regular polygons. Demonstrates the application of the algorithm with a hand-held calculator and an Apple computer. Provides a program to calculate pi in Pascal programing language. (12 references) (MDH)

This article explores the multiple representations (verbal, algebraic, graphical, and numerical) that can be used to study the golden ratio. Emphasis is placed on using technology (both calculators and computers) to investigate the algebraic, graphical, and numerical representations. (JAF)
