A discussion is given of calculators in the classroom. Opinions and recommendations of various groups are incorporated. (MK)

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)

A description is given of an approach to teaching a remedial mathematics course using calculators as a complete substitute for paper-and-pencil calculation. (MP)

Specially designed materials were used for teaching trigonometric ratios to 131 ninth- and tenth-grade students, one group using calculators and one not. Results on achievement were mixed. (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…

Presents five guided activities that use a graphing calculator to help students discover the fundamental theorem of algebra. Includes student worksheets and illustrates solutions. (KHR)

Considers the impact of the introduction of graphic calculators into assessment within the International Baccalaureate Diploma. Discusses difficulties that arise in the development of practice questions, how these difficulties were resolved in the questions that appeared on the examinations, and problems of different calculator syntax. (Author/KHR)

Suggests use of the quadratic formula to build understanding that connections between factors and solutions to equations work both ways. Making use of natural connections among concepts allows students to work more efficiently. Presents four sample problems showing the roots of equations. Messy quadratic equations with rational roots can be solved…

Describes a framework to help teachers decide when to use calculators with their students. (YDS)

Uses a Calculator-Based Ranger and a graphing calculator in problem-solving mode to introduce an exploration of graphing-related concepts including intercepts, slopes, and rate of change. (YDS)

Describes the use of calculator based laboratory (CBL) technology in monitoring the process of chemical reactions. Explains the estimation of infinity readings and criteria to choose t values. (YDS)

Presents mathematical calculator activities used by students individually, in small groups, or as problems of the week. Suggests using calculators to enhance and stimulate student learning. (KHR)

Discusses numerical methods to compute approximate solutions of a differential equation. Provides a Pascal program for the extended Euler-Heun method. (YP)

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)
