Presents a way to examine in depth the polynomial approximation of a transcendental function by using graphing calculators. (ASK)

Technology offers the opportunity to study larger, more difficult group structures and perform tedious computations quickly while maintaining the focus on concepts over calculations. Explores several technology options available to the instructor as well as sample assignments and class explorations that effectively integrate technology within the…

Describes a mini-experiment on how the TI-92 might fit into normal classroom learning and considers students' initial reactions to the calculator. (Author/ASK)

Provides experiences of teaching students who had the use of a TI-92 for the semester, both in and out of class, with a greater emphasis on modeling and qualitative graphical methods and decreased emphasis on explicit solution techniques. Indicates that the TI-92 proved to be an invaluable tool for this course. (Author/ASK)

One problem that students have with mathematics is that they often view the topic as a series of unrelated ideas. Sometimes they are aware that they have to know one concept to move to the next, but what is done in geometry is not necessarily related to anything in algebra. This failure to recognize mathematical connections limits students'…

This report summarizes findings on strategies chosen by students (n=38) when solving algebra problems related to various functions with the freedom to use a TI-83 graphing calculator, influences on student problem-solving strategy choices, student ability to approach algebra problems with use of multiple representations, and student beliefs on how…

This paper presents the features of graphic calculator technology that can be implemented in noncalculus-based educational statistics courses. The objectives are to: (1) present potential uses of the graphing calculator; (2) discuss current research concerning graphing calculator implementation in the classroom; and (3) illustrate current…

The purpose of this study was to determine the effect of the TI-81 Graphics Calculator as an instructional tool on college algebra students' conceptual and procedural achievements involving functions and graphs and on the students' attitudes toward mathematics. The study was a posttest-only, equivalent control group design conducted with students…

The relationship between college students' preferred mode of processing mathematical information--visual or nonvisual--and their performance in calculus classes with and without technology was investigated. Students elected one of three different versions of an introductory differential calculus course: using graphing calculators, using the…

In this report, we give a sociocultural account of the mediating functions handheld graphing calculators and social interaction play in students' mathematical understanding. We discuss the evolution of students' abilities to symbolize, model, and develop collective mathematical practices about polynomial inequalities in instrumented activity. In…

Analysis of student achievement data following the introduction of graphics calculators to tertiary entrance examinations in mathematics in Western Australia suggests the possibility of an equity problem between the sexes in their usage. While males out-performed females in a number of categories, the most conclusive evidence emerged in questions…

In recent years, there has been a growing interest in the use of graphing technology for the teaching of mathematics. This interest has been, in part, sparked by the recommendations of the National Council of Teachers of Mathematics (NCTM) Standards and "Everybody Counts: A Report to the Nation on the Future of Mathematics Education."…

This issue of Mathematics Education Dialogues focuses on the nature and the role of algebra in the K-14 curriculum. Articles on this theme include: (1) "Algebra For All? Why?" (Nel Noddings); (2) "Algebra For All: It's a Matter of Equity, Expectations, and Effectiveness" (Dorothy S. Strong and Nell B. Cobb); (3) "Don't Delay: Build and Talk about…

This paper presents two mathematics activities that model functions studied using the Calculator Based Ranger (CBR) software for TI-82 and TI-83 graphing calculators. The activities concern a bouncing ball experiment and modeling a decaying exponential function. (ASK)

This collection of activities is designed to show how TI-Interactive[TM] and Calculator-based Laboratories (CBL) can be used to explore topics in high school science. The activities address such topics as specific heat, Boyle's Law, Newton's Law of Cooling, and Antarctic Ozone Levels. Teaching notes and calculator instructions are included as are…
