Presents a summary of the arguments for and against calculator use in teaching mathematics. Includes an overview of research and suggestions for calculator use in the classroom. (PK)

Four worksheets designed to be used with calculators are presented. For levels 1-2, counting is the focus; levels 3-4, estimation; levels 5-6, use of memory keys; and for levels 7-8, patterns. (MNS)

New approaches to the teaching of introductory algebraic concepts are discussed. Their use in the Approaching Algebra Numerically Project in some middle schools in Ohio is reviewed. Some implications for use in Australian schools are considered. (MNS)

Activities to extend the core curriculum through the study of the periodicity of rational numbers to help students develop calculator and research skills are presented. Four worksheets are included, to be used as discovery activities. A computer program is listed, as well as examples of periodic pictures. (MNS)

More sophisticated graphing calculators available for college students can be incorporated into college algebra classes to result a higher student achievement. For this purpose, in this study 117 college students were randomly assigned into either experimental groups where students were allowed to the use of graphing calculators or control groups…

This paper describes how a researcher developed task and four different data collection instruments provide evidence for the identification of various affordances of a technology-rich teaching and learning environment (TRTLE) that were perceived and/or enacted by Year 9 students in their solution of a linear function task utilising a graphing…

The Health Sciences and Technology Academy (HSTA), administered through West Virginia University, provides professional development to science teachers who partner with higher education faculty in a science and math enrichment program for financially disadvantaged African American students. This program focuses on human nutrition and has…

Studies concerning the impacts of electronic calculators on mathematics-related achievement and attitudes were reviewed. Results showed support for the computational benefits due to calculator use, but support for conceptual benefits was minimal. Hypothesized changes in general attitudes toward mathematics for those using calculators was…

Presents 14 problems organized into three levels of difficulty. Topics include algebra, pattern identification, probability, and geometry. Includes solutions to the problems. (DDR)

Secondary mathematics teachers participated in a problem-solving course in which technology became a means to develop as teachers and as problem solvers. Findings indicate a delineation between technical competence and metatechnology--thinking about how and when to apply technology to particular problems. (PVD)

Discussed are supercalculator capabilities and possible teaching implications. Included are six examples that use a supercalculator for topics that include volume, graphing, algebra, polynomials, matrices, and elementary calculus. A short review of the research on supercomputers in education and the impact they could have on the curriculum is…

Describes mathematical problems which occur when using the computer as a calculator. Considers errors in BASIC calculation and the order of mathematical operations. Identifies errors in spreadsheet and calculator programs. Comments on sorting programs and provides a source for Mathemagical Black Holes. (MVL)

Discusses research findings related to students' ability to make connections between analytical (symbolic) and graphical representations of functions in calculus. Describes graphing tasks and typical student interpretations. Implications for teaching are suggested. (Contains 17 references.) (MKR)

Summarizes research conducted within a series of professional development workshops for teachers in grades K-8 which emphasize basic reasoning skills, integrating manipulative materials, and technology. Demonstrates these principles using patterns, relations, and functions as examples. (Author/MKR)

Describes how graphing calculators can be used to explore different functions, from linear to higher degree polynomials. "Globs" (circles) are drawn around randomly plotted points on the screen, and students devise functions that pass through as many of these globs as possible. Variations on the game are also mentioned. (DPM)
