This paper argues that using Computer Algebra Systems (CAS) to teach 12- to 18-year-old students is going to change teaching methods, the content of what has been taught, and exams. Traditional exam questions are analyzed and categorized according to their usefulness in a CAS environment. The goal is to give teachers new perspectives with which to…

This paper describes a classroom, instructor-led activity designed to show how graphic calculators can be used to explore coordinate geometry. The activity involves digitizing an image of a hand and transforming the image through geometrical transformations. Teaching notes and calculator instructions are included as are blackline masters. Also…

This project description is designed to show how graphing calculators and calculator-based laboratories (CBL) can be used to explore topics in the physics of sound. The activities address topics such as sound waves, musical notes, and chords. Teaching notes, calculator instructions, and blackline masters are included. (MM)

Presents an activity on solving equations of the form ax+b=Sqr(cx=d) using graphing calculators. (ASK)

Discusses the results of research which examines the perceptions of teachers as they initially engage in instruction using graphing calculators. Data were collected from 261 math and science teachers of grades 6-12. Participant views changed significantly overall in favor of viewing the graphing calculator as a thinking tool to enhance conceptual…

Presents two examples of using the limitations of calculators to help students understand important mathematical ideas. The first example shows how a simple algebraic calculation can make a recursive model work long enough to perform the job at hand while the second shows how the limitations of a calculator can be used to introduce the need for…

Presents a discovery activity that connects mathematics and the world of entertainment. Combines geometric transformations with a calculator's DRAW, MATRIX, and PRGM features to generate visual reinforcement of mathematical concepts. (Author/NB)

Aims for students to use a combination of stochastic ideas to simulate a basketball tournament. Uses the TI-83 calculator in the activity to simulate the binomial distribution. (KHR)

Calls for the use of the zoom feature of graphing calculators to help students better understand the concept of derivatives. (MKR)

Discusses mathematics as analogous to a tree with many branches. Contends that technology, especially the graphing calculator, can help students see the sun and sky through the many branches and leaves. (MKR)

Presents an investigation of a third-degree polynomial using a TI-82 graphing calculator. Also includes an algebraic solution. (MKR)

Presents an experiment carried out at the University of Groningen where pretest-posttest design was used including two experimental conditions with the graphics calculator (TI-81) and one control condition without the calculator. Results point toward a change in teacher instructional behavior and in pupils' problem-solving approaches. Contains 14…

Presents an investigative process of conjecture followed by proof by induction using a combination of manipulatives and technology, placing special emphasis on the use of different representations. (ASK)

Describes the implementation of graphing calculators as teaching and learning aids in an intermediate linear algebra unit at the undergraduate level. Outlines the approach taken and discusses the problems that arose in relation to calculator use. (ASK)

Focuses on three activities using the TI-92 graphing calculator that examine the relationship between the intensity of a light source and its distance from a measurement point, properties of a sound wave, and the relationship between the time elapsed and the temperature of a cooling substance. (ASK)
