A study of the effect of the use of calculators on student computational ability is reported. Results showed that treatment groups using calculators gained significantly more whole number computational ability than control groups not using calculators. Interaction between sex of student and calculator usage was not significant. (DT)

Arguments for and against the use of hand calculators in school mathematics are presented. (DT)

The place of binary arithmetic in the curriculum is discussed, then uses of binary coding for methods of automatic error correction in computers and calculators are analyzed. (DT)

A method is explained for using the calculator to determine the day of the week on which any given date falls. (DT)

The study analyzed gender attitudes of students in learning mathematics by using a calculator, in one of Botswana's Junior Secondary Schools. Students' attitudes were sought using a questionnaire and data was analyzed by both quantitative and qualitative methods. Attitude variables used were usefulness of calculators, enjoyment and anxiety in…

In this report, we give a sociocultural account of the mediating functions handheld graphing calculators and social interaction play in students' mathematical understanding. We discuss the evolution of students' abilities to symbolize, model, and develop collective mathematical practices about polynomial inequalities in instrumented activity. In…

This paper examines to show how an investigative approach to mathematics teaching can honor its two important dimensions--a thinking and reasoning side to go with the skill development. The paper addresses the question of why a problem solving approach has failed, makes the case for investigations as an overarching organizer, and discusses the…

Analysis of student achievement data following the introduction of graphics calculators to tertiary entrance examinations in mathematics in Western Australia suggests the possibility of an equity problem between the sexes in their usage. While males out-performed females in a number of categories, the most conclusive evidence emerged in questions…

This collection of essays examines the history and impact of computers in mathematics and mathematics education from the early, computer-assisted instruction efforts through LOGO, the constructivist educational software for K-9 schools developed in the 1980s, to MAPLE, the computer algebra system for mathematical problem solving developed in the…

In recent years, there has been a growing interest in the use of graphing technology for the teaching of mathematics. This interest has been, in part, sparked by the recommendations of the National Council of Teachers of Mathematics (NCTM) Standards and "Everybody Counts: A Report to the Nation on the Future of Mathematics Education."…

This issue of Mathematics Education Dialogues focuses on the nature and the role of algebra in the K-14 curriculum. Articles on this theme include: (1) "Algebra For All? Why?" (Nel Noddings); (2) "Algebra For All: It's a Matter of Equity, Expectations, and Effectiveness" (Dorothy S. Strong and Nell B. Cobb); (3) "Don't Delay: Build and Talk about…

This paper presents two mathematics activities that model functions studied using the Calculator Based Ranger (CBR) software for TI-82 and TI-83 graphing calculators. The activities concern a bouncing ball experiment and modeling a decaying exponential function. (ASK)

This collection of activities is designed to show how TI-Interactive[TM] and Calculator-based Laboratories (CBL) can be used to explore topics in high school science. The activities address such topics as specific heat, Boyle's Law, Newton's Law of Cooling, and Antarctic Ozone Levels. Teaching notes and calculator instructions are included as are…

This paper discusses uses of TI-73 graphing calculators for middle school mathematics students. It indicates that with the appropriate use of the TI-73, students can develop understanding about variables and basic concepts of algebra, and explore mathematical topics. Background on middle school students' difficulties with those subjects is…

The central premise of this study was that the use of graphing calculator technology helped improve students' achievement in upper level biology courses. The populations studied included high school students in a block course entitled "AP Biology/AP Calculus" and students in a traditional AP Biology course. There appears to be a positive effect on…
