The use of technology allows students to look at mathematical concepts in many different ways. With a variety of perspectives, studying ideas that were at one time difficult to understand are possible. Mathematics learning focuses more on concepts and less on computations. Various sequences including arithmetic, geometric, and partial sum can be…

Discusses the properties of the equation y"+ay=0, a basic equation in differential equations classes which is well known to have periodic solutions. Explores similar but more complicated equations using a graphing calculator to ask questions about the nature of the solutions and to generate conjectures from examples. Lists some equations and…

Explores how students interpret algebraic notation and what teachers can do to support appropriate interpretations. Presents two research-based strategies and concludes that in the face of reform and technological advances, finding a definition for symbol sense takes on added significance. Contains 22 references. (ASK)

One way to assist students in developing correct intuitive ideas about the effect of sample size is to allow students to simulate similar problems. Describes experiences with classes performing simulation using graphing calculators. (ASK)

Describes an experiment with two participants, one of which is familiar with the Geometer's Sketchpad but not with Cabri-Geometre and vice versa. Displays the work of both participants when they are given two geometry problems in secret and 20 minutes to work on each, the first with software that they are familiar with and the second using the…

Presents two problems whose solutions can be enhanced using the Geometer's Sketchpad to solve the problems. Concludes that available computer technology can aid in the analysis and solution of some interesting geometry problems. (ASK)

Presents activities in which students are invited to re-create on their calculator screen images using graphical features of the graphing calculator. (ASK)

Presents a mathematics activity using hand-held technology that can be used with elementary school students. Uses graphing calculators and calculator-based laboratories in this activity. (Contains 11 references.) (ASK)

The HeadJam series is comprised of six programs exploring mathematics, science, and critical thinking skills. It is an award-winning, educational videotape series for middle school students that explores multi-disciplinary skills in a highly entertaining way. The teacher's guide and 22-minute video, "Go Figure," demonstrate how math is…

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

Discusses reasons for using spreadsheets in mathematics education. Presents mathematics activities for beginning algebra classes using spreadsheets. (ASK)

Shows how the joint use of a dynamic geometry program and a spreadsheet can provide a computational environment for exploring geometry on plane lattices that lessens the risk of developing the false empiricist view of mathematics often associated with the use of information technology. Contains 17 references. (Author/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)

Discusses more effective uses of assessment techniques in mathematics classrooms. Presents some examples of powerful assessment techniques. (ASK)
