Aitchison, Kate – Micromath, 2001
Provides a lesson plan designed to form three one-hour sessions with mixed ability groups of 11-12 year olds. The activity involves students estimating road distances by counting the number of map grid lines crossed in going from A to B. The activity is designed to introduce students to graphing calculators. Screenshots from the calculator are…

Stylianou, Despina A.; Smith, Beverly; Kaput, James J. – Journal of Computers in Mathematics and Science Teaching, 2005
This article reports on results of an exploratory study on undergraduate pre-service teachers' understanding of graphical representations of motion functions. The study described pre-service teachers' explorations using a CBR device. Pre-service teachers' growth was studied in two dimensions: (a) in their learning of the mathematics involved and…

Gordon, Sheldon P.; Gordon, Florence S. – Mathematics and Computer Education, 2004
Probably the one "new" mathematical topic that is most responsible for modernizing courses in college algebra and precalculus over the last few years is the idea of fitting a function to a set of data in the sense of a least squares fit. Whether it be simple linear regression or nonlinear regression, this topic opens the door to applying the…

Ford, Roger – Mathematics Teacher, 2004
A Mandelbrot mathematical set is an object with endless borders, and in the present exercise a graphing calculator is used to identify and examine the set points. The significance and power of technology is also displayed in the understanding and solving of problems.

Madden, Sean P.; Wilson, Wayne; Aichun Dong; Lynn Geiger; Mecklin, Christopher J. – Journal of Chemical Education, 2004
A demonstration, which shows that the graphing calculation can greatly supplement the computer and often eliminates the need for computers and science, is given. The graphic calculator is a handheld computer, more powerful than most sophisticated computer of 25 years ago.

Swingle, David A.; Pachnowski, Lynne M. – International Journal of Mathematical Education in Science and Technology, 2003
Discusses a real-world problem-solving lesson that emerged when a high school math teacher used a motion detector with a CBL and graphing calculator to obtain the bounce data of a ping-pong ball. Describes the lesson in which students collect bad data then fill in the missing parabolas that result using critical components of parabolas and…

Madden, Sean P.; Downing, James P.; Comstock, Jocelyne M. – Mathematics Teacher, 2006
This article describes a classroom activity in which a solar eclipse is simulated and a mathematical model is developed to explain the data. Students use manipulative devices and graphing calculators to carry out the experiment and then compare their results to those collected in Koolymilka, Australia, during the 2002 eclipse.

Morse, Dana F. – Texas Instruments, 2007
This study took place at Skaneateles High School in Skaneateles, New York in a grade 10 Integrated Math AB course with 52 students in 3 sections using the TI-84 Plus family graphing calculators and the TI-Navigator classroom learning system with a projector and interactive whiteboard. New York State is phasing in a new curriculum that integrates…

Martin, William O. – 1994
Technologies play a prominent role in current reforms of school and collegiate mathematics. This study examined ways in which first-semester calculus students still showed the influence of a graphing-intensive college algebra course they had studied one or two semesters earlier. Students (n=18) at a large research university were asked to solve a…

Pierce, Robyn – International Group for the Psychology of Mathematics Education, 2005
The study of linear functions is important as it provides students with their first experience of identifying and interpreting the relationship between two dependent variables. This paper, which builds on previous research, reports a study undertaken with 64 year 9 students from two Australian schools. Linear functions were introduced to these…

Zoltek, S. M.; Dick, S. S. – 1997
This paper presents teaching strategies and examples developed for a two-semester sequence in quantitative problem solving, specifically outlining a non-calculus derivation of linear regression formulas supported by the graphical display of the TI-83 calculator to visualize the minimization of the sum-squared vertical distances. The paper…

Perera, Vic – 2002
This paper presents some ideas on how to utilize TI-83 Plus calculators to perform division of one polynomial (the divided) by another polynomial (the divisor) and how that procedure might be incorporated into a college algebra lesson. Four ways to obtain the quotient and remainder when dividing a polynomial by a first-degree polynomial are…

Ryan, Walter F. – 1999
This study extended over three months and involved 344 subjects. It compared the performance and attitudes of seventh-grade students taught geometry using the TI-92 calculator and a supplementary activity manual written to be used with the TI-92 calculator with the performance and attitudes of students using the traditional approach. On a…
