Although the nature of the research varies, as do concepts of angle, research in general supports the supposition that angle is a complex idea, best understood from a variety of perspectives. In fact, the concept of angle tends to be threefold, consisting of: (1) the traditional, static notion of two rays meeting at a common vertex; (2) the idea…

Suggestions for using handheld calculators are given. Students can invent and check their own problems. The calculator can debug problems, provide practice, aid in developing concepts of place value, decimals, order of operations, powers of a number, and evaluation of formulas. (KM)

A program is presented which enables a programable calculator to become a device to check the arithmetic computational skills of students. (MP)

Suggestions are given for using the calculator in junior high classrooms. Square roots, factoring, and percentages are some topics discussed. A worksheet is included. (MP)

Taking advantage of calculators involves becoming knowledgeable about the research on calculators, recognizing intangible benefits of calculator use, developing an open calculator policy, allowing students to explore with calculators, never requiring calculator checks of paper-and-pencil computations, using standardized tests designed for…

Defines psychic intelligence as an inclination all children possess to use whatever cognitive intelligence they have for learning, adaptive behavior, and pleasure; strongly suggests that algorithmic drill usually damages the mentality of children by stifling psychic intelligence; and discusses the use of pocket calculators to prevent this effect.…

This book is designed to familiarize instructors and students with the Texas Instruments Explorer Plus calculator and provide background information and activities for including the calculator in the mathematics curriculum. Materials are included for three workshops and 26 lessons. Lessons are organized by common mathematical topics making it…

The purpose of this study was to investigate the meanings that a teacher associated with calculators as reflected in the teacher's use of calculators in two 12th-grade mathematics courses, and to link those meanings to the institutions and individuals that supported the development of those meanings. By describing the teacher's conceptions of his…

Included are a detailed example of a calculator demonstration, the general principles to be followed in preparing a calculator demonstration, a list of demonstration topics for a calculus course, and some suggested topics for other courses. (MK)

An activity is described for introducing some fundamental notions in inferential statistics to students in elementary high school statistics courses. (MP)

Demonstrates the capabilities of graphics calculators in assisting with a simple mathematical investigation. Subjects covered include Direct Calculation, Tables, Graphing Particular Cases, Logarithms, Parametric Solutions, and Three-Dimensional Plots and Contours. The question posed for investigation with the calculator is, for what pairs of…

Questions students raise about the meaning of zero to the zero power present an opportunity for mathematics teachers to involve students in active participation in exploring mathematical relationships. Calculators are the needed tool to make this exploration accessible to students. How they can be used is described. (MNS)

Criticizes the method of using calculators for the purpose of selecting candidates for L, for the limit value of a function. Suggests an alternative: a working formula for calculating the limit value L of a real function in terms of infinitesimals. (Author/ASK)

Describes a research and development project whose main focus is the use of Computer Algebra Systems (CAS) in mathematics classrooms and the didactical possibilities linked with its use. Focuses on the possibilities and problems of cooperation between theory and practice and between mathematics educators and teachers. (Author/MM)

The students need not compute dependent values required in making line graphs but to teach the students the usage of graphing calculator to plot, calculating and graph linear equations, which are best suited to real world data. In this initial learning process, the teacher should give minimum support to the students in arriving at a solution as…
