This article on mathematics in the curriculum describes how students learn the characteristics of conic section equations by entering them into graphing calculators to make happy faces in a high school or college algebra class. A sample worksheet page is included. (Author/LRW)

Discusses the importance of calculators in the teaching and learning of mathematics. Argues that affordable graphing calculators let all mathematics students use computer visualization on a regular basis for both in-class and out-of-class activities. (ASK)

Why calculators should be used for testing, as well as for instruction, is discussed. The focus of the curriculum would shift from computation to deeper development of concepts and to mathematical modeling. A broader curriculum would result. (MNS)

Explores the effects of varying the coefficients in the general quadratic function using graphing calculators. (MKR)

Examines what students think about calculators and their use in school by utilizing a short questionnaire. Concludes that children had mainly positive views about the calculator although much of it still remained a mystery, and none of them appeared particularly confident in using it. (ASK)

Presents examples in which the graphing calculator can provide students with particularly valuable insights into some major statistics ideas such as random numbers. (ASK)

Describes a calculator program that graphs and indicates the main features of the conic whose second-degree equation includes a nonzero xy-term. The program indicates coefficients of conic in a rotated coordinate system, type of conic, angle of rotation, coordinates of vertices of conic in the original coordinate system, and a graph of conic…

Discusses the appropriateness of lower secondary school students using graphics calculators instead of scientific calculators. (ASK)

The issue of calculator use in the Adult Basic Education/General Education Delivery (GED) classroom has arisen because of a recommendation that calculators be permitted on the mathematics part of the GED test. Teachers and supervisors are challenged to make calculator use enhance mathematics education. (JOW)

Discusses the heated debates in education recently over the use of calculators in mathematics. Argues for the urgent need of calculators to be introduced into arithmetic lessons in primary schools. (ASK)

Focuses on solutions to a single problem using both induction and deduction by utilizing a TI-82 graphing calculator to illustrate symbolic, numerical, and graphical approaches to the problem. (ASK)

Reports on how students managed some technical aspects of graphics calculators as they used them to study graphs of straight lines and parabolas. Identifies three common student difficulties: (1) tendency to be unduly influenced by the jagged appearance of graphs; (2) poor understanding of the zoom operation; and (3) limited grasp of the processes…

Reviews recent research into the effectiveness of the graphing calculator as a tool for instruction and learning within precalculus and calculus, specifically in the study of functions, graphing, and modeling. Contends that much research fails to provide clear guidance or informed debate regarding the role of graphing calculators in mathematics…

Uses the visual and programming capabilities of the graphing calculator to discern both differences and similarities between two independent collections of sample data. (MKR)

Demonstrates the principal concept and the application of MAPLE in mathematical education in various examples. Discusses lengthy and abstract topics like the convergence of Fourier series to a given function, performs the visualization of the wave equation in the case of a vibrating string, and computes the oscillations of an idealized skyscraper…
