This paper introduces a teaching unit on using spiral symmetry in a geometry course for secondary education majors. The TI-92 graphing calculator is used to exploit the exponential function to analyze the geometric topic of similarity and to study the derivative of spirals. The paper provides some procedures and programs to generate spirals using…

This study explores a program designed to revolutionize developmental mathematics at the college level using the new handheld computer algebra systems and new information about the ways in which students learn mathematics. Students in one class of developmental algebra worked with the new approach to learn algebra by building on their intuitive…

The purpose of this study was to investigate the effects of the Casio 9850 and the TI-85 graphing calculators on college students' procedural skills and conceptual understanding in two different developmental mathematics courses. The courses used in this study were Elementary Algebra and Intermediate Algebra. Both the non-graphing calculator group…

This paper discusses how students' participation in conversation and classroom activities potentially evidences and constitutes their cognition. Participation is viewed in terms of reflective discourse, a construct from the literature, and is described in the context of two Year 11 students together designing a simple aplet for their graphics…

In this presentation we will investigate the mathematics and physics of a free-falling object, not for the purpose of research to discover some profound physical phenomena, but rather to enhance students' ability to gather, organize, and analyze data using state of the art hand held technology. We will use the TI-83 plus (a sophisticated graphing…

This collection of activities is designed to show how graphing calculators can be used to explore statistics. The activities address such topics as data representation, distributions, and statistical tests. Teaching notes and calculator instructions are included as are blackline masters. (MM)

A proposal for teaching how to graph functions is presented on the basis of the teaching theory of didactical situations implemented by the French author Guy Brousseau. The proposal is aimed at students in 12th grade in high school (USA) or in a freshman calculus course. The TI-92 graphic calculator was used as a teaching aid. (Author/ASK)

Describes an activity presented in sports fishing magazines on developing a formula that predicts the weight in pounds of a game fish given its length in inches by using a TI-83 graphing calculator. Highlights the importance of using real-life problems and mathematical explorations. (ASK)

Presents activities to find Pythagorean triples using the TI-83, a graphing calculator. (KHR)

Addresses the "T-cubed" or Teachers Teaching with Technology program and their courses utilizing hand-held technology such as graphic calculators, data-loggers and the TI-92 hand-held computer. Describes practical experiments involving discharge, a temperature probe, and an oscillating water sprinkler. (AIM)

Presents four methods for solving a quadratic equation using graphing calculator technology: (1) graphing with the CALC feature; (2) quadratic formula program; (3) table; and (4) solver. Includes a worksheet for a lab activity on factoring quadratic equations. (KHR)

Graphing calculators convert an equation to a visual model allowing students to make connections between mathematical concepts. Teachers are very receptive to the calculators, according to the director of the Calculator and Computer Precalculus Project at Ohio State University. (MLF)

Reviewed are 13 computer software packages including "Algebra I Second Semester"; "The Algebraic Proposer"; "SVE AutoGraph"; "Geometry: Concepts and Proofs"; "Geometry 1&2"; "Graphics Calculator"; "Interactive Physics"; "Learning Data Analysis with Data Desk";…

Describes the graphing calculator as a new graphical approach to standard physics problems. Presents a collision problem to illustrate its use. (JRH)

Compared the performance of (n=710) college students taught precalculus using a graphing calculator approach to the performance of students using the traditional approach. Students in the first group scored significantly higher than the others on a comprehensive final exam. (16 references) (Author/MKR)
