Describes an activity in which students investigate the symmetry of factor sets of composite numbers using the TI-83 graphing calculator. This activity allows students to observe patterns, make predictions, and verify their accuracy. (ASK)

Presents a lesson that uses a motion detector in order for students to experience the interplay between motion and its graphical representation of the slope. Focuses on the change in the appearance of the graph with regard to changing speed. (ASK)

Discusses the graphing and other technical capabilities of the TI-83. Demonstrates possible uses of it in mathematics classrooms. (ASK)

Presents a study on calculus reform that examines how instructional approaches that place different emphases on the use of technology and multiple representations impact undergraduate calculus students' ability to use and understand connections between different representations of concepts. Compares three courses--traditional calculus, calculus…

Identifies and describes some of the mathematics curriculum issues associated with graphing calculators such as equity, role of calculators, content and sequencing, textbook design, learning to use a calculator, worksheets, student decision-making, calculator dependence, assessment, electronic algorithms, multiplying choices, calculator…

The abstract nature of the mole and its applications to problem solving make learning the concept difficult for students, and teaching the concept challenging for teachers. Presents activities that use concept maps and graphing calculators as tools for solving mole problems. (ASK)

Reports on a study replicating and extending a previous study examining the effects of the TI-92 graphics calculator and calculus instruction on students' success in calculus. Finds that students using a TI-92 had significantly better performance on the final exam and overall course grade than students using other calculators, and student-centered…

Showcases applications of mathematics designed to demonstrate to students how the topics under study are used in the real world or to solve problems. Presents an activity on thermal systems using spreadsheets or graphing calculators. (ASK)

Presents an opportunity for students to become familiar with the fundamental premise of iteration for a new branch of mathematics that is known as chaos theory by using graphing calculators. (ASK)

Focuses mainly on a common example in technology-rich mathematics curricula, namely the line of best fit, followed by a discussion of two additional examples, interpolating polynomials and complete graphs. (ASK)

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)

Least squares regression is the most common method of fitting a straight line to a set of bivariate data. Another less known method that is available on Texas Instruments graphing calculators is median-median regression. This method is proposed as a simple method that may be used with middle and high school students to motivate the idea of fitting…
