Entering a value into a calculator and repeatedly performing a function f(x) on the calculator can lead to the solution of the equation f(x)=x. Explores the outcomes of performing this iterative process on the calculator. Discusses how patterns of the resulting sequences converge, diverge, become cyclic, or display chaotic behavior. (MDH)

Describes a teaching experiment in which spreadsheets and computer algebra systems were used to teach a low-level college consumer mathematics course. Students were successful in using different types of functions to solve a variety of problems drawn from real-world situations. Provides an existence proof that computer algebra systems can assist…

Presents a program in the United Kingdom that trains every serving teacher and trainee teacher how to use Information and Communication Technology (ICT) to teach their subjects more effectively. Discusses mathematics education related to this part of the program. (ASK)

Least squares regression is the most common method of fitting a straight line to a set of bivariate data. Another less known method that is available on Texas Instruments graphing calculators is median-median regression. This method is proposed as a simple method that may be used with middle and high school students to motivate the idea of fitting…

This article focuses on three key factors that a survey of literature indicated impact the teaching and learning of mathematics with graphing calculators: access to graphing calculators, the place of graphing calculators in the mathematics curriculum, and the connection between graphing calculators and pedagogical practice. Access to graphing…

This paper discusses the results of questionnaires sent to principals and teachers on the subject of manipulatives, computer, and calculator availability and use in the classroom. The study was done in order to develop a better understanding of teachers' inservice needs. Results of the study include: (1) most teachers have at least some…

This document is a verbatim transcription of an interview conducted by Thomas C. O'Brien under the auspices of the Teacher's Center Project of Southern Illinois University at Edwardsville. The transcript presents the views of Professor A. I. Weinzweig for the University of Illinois at Chicago Circle. Distinctions between training and education,…

This document was initiated with the collection of 150 questions in telephone interviews of a national sampling of junior high school and high school teachers. A Mathematics Consultant Panel reviewed the questions, and selected topics were developed, for which there were research bases for answers. The material covers: (1) Effective Mathematics…

Presented is a third supplement to previous lists of references. This document is a compilation collected by the Calculator Information Center between March 1982 and March 1983. Included are references which previously appeared on bulletins distributed by the center, plus articles in newsletters and similar less readily available sources and from…

This document consists of two major parts. The first, titled Initial Comments, discusses the motivation for creating this material, provides a list of minimal characteristics in calculators for various educational levels, notes a number of basic assumptions on calculator use, and discusses curriculum concerns regarding effects of calculators. The…

This monograph was designed primarily to develop awareness of the benefits of using calculators to teach mathematics in grades K-8 and to provide teachers with some specific teaching ideas. The first section, on the rationale for using calculators, presents position statements from various groups and answers some questions about the use of…

Twelve research reports related to mathematics education are abstracted and analyzed. Three of the reports deal with aspects of learning theory, two with student characteristics, and one each with calculators, problem solving, secondary mathematics curriculum changes in Australia, sex differences, teaching methods, and tutoring strategies. The…

Presented is a second supplement to previous lists of references. This document is a compilation of information collected by the Calculator Information Center between December 1980 and March 1982. Included are references which previously appeared on bulletins distributed by the center, plus articles from newsletters and similar less readily…

This is a supplement to a previous collection of expanded abstracts of research with calculators. Eight dissertations are abstracted, to add to the fund of information on the effects of calculators on achievement and learning. The critical commentary prepared by each abstractor pinpoints particular strengths and weaknesses of each study. (MS)

Two teachers share practical tips for teaching secondary school mathematics. The tips focus on effective use of homework and teaching trigonometric concepts. (PK)
