Explores the concept of extraneous roots in radical equations using an alternative to traditional algebraic methods. Using calculator- or computer-based graphs, accounts for extraneous roots by examining the four possible cases of systems of equations that can produce the solution to the radical equation. (MDH)

Presents activities in which students develop and analyze scatterplots on graphing calculators to model corn growth, decay, a box of maximum volume, and weather prediction. Provides reproducible worksheets. (MDH)

Running experiments and grabbing experimental data are great ways to learn and teach science and mathematics. Data grabbers are instruments that capture physical data in electronic form for graphing and analysis in graphing calculators and computers. Describes some data grabbers and points to items in their gigantic support system. (PVD)

The purpose of this study was to examine rural and non-rural students in order to understand similarities and differences between their learning styles and the ease with which they learned Algebra with a graphic calculator. Two samples of students, one from a rural high school and one from a non-rural one, answered a survey asking about their…

The National Council of Teachers of Mathematics (NCTM) Curriculum and Evaluation Standards puts great stress on the mathematical processes of problem solving, communication, reasoning, and making connections. NCTM standards also emphasize new and emerging content areas for middle school students such as algebra, data analysis, and probability.…

This paper presents a comparative analysis of the Western Australian Calculus Tertiary Entrance Examination (TEE) papers for 1996-99, two years before and two years after the introduction of graphics calculators on the examination. Changes in the questions that asked students to graph rational functions and students' answers to the corresponding…

This book contains descriptions of the 122 Summer Science Camps (SSC) funded by the National Science Foundation (NSF) from 1992 to 1996. This program is employed as an early intervention strategy that reaches out to a large number of disadvantaged children who are underrepresented in scientific and technical careers. The main goal of the SSC is to…

Explores the role that symbolic-graphical calculators can play in the current calls for reform in the mathematics curriculum. Discusses symbolic calculators and graphing calculators in relation to problem solving, computational skills, and mathematics instruction. (MDH)

Discusses integrating mathematics/science with measurement for grades 6-12. Provides Web addresses for companies manufacturing data grabbers (instruments for gathering data in electronic form for graphing and analysis by graphing calculators and computers) and for sites offering instructional materials. Describes projects in architecture,…

In a two-day workshop, 12 teachers who had not previously used graphics calculators not only learnt how to use a calculator but also completed calculator tasks designed to explore their misconceptions and then learnt about students' difficulties. Observation of lessons taught subsequently by 6 of the teachers, and interviews with 15 of their…

This document contains the first volume of the proceedings of the 26th Annual Conference of the International Group for the Psychology of Mathematics Education. Conference presentations are centered around the theme "Learning from Learners". In total, 290 presentations were given ranging from the psychology of mathematics in the very…

This volume contains the proceedings of the International Conference on Technology in Mathematics Education (TIME 2000). It includes papers, posters, and short oral reports. Research papers include: (1) "Implications of the Shift from Isolated Expensive Technology to Connected, Inexpensive, Ubiquitous and Diverse Technologies" (Jim…

This book looks at how practitioners have focused on the fully educational application of intellect to the problem of developing mathematical thinking among one's pupils. Each chapter demonstrates reflective minds at work, relying on close observation, willingness to understand the student's thinking processes and patient commitment to students…

Discusses the use of technology in solving compound interest-rate problems that can be modeled by linear relationships. Uses a graphing calculator to solve the specific problem of determining the amount of money that can be borrowed to buy a car for a given monthly payment and interest rate. (MDH)

Texas Instruments has undertaken a research program with the goal of producing scientifically-based evidence of the effectiveness of graphing calculators and the "TI-Navigator"[TM] classroom networking system in the context of a professional development and curriculum framework. The program includes a two-year longitudinal study. The…
