This paper explores the potential of mobile devices to support novel forms of mathematics classroom activity. In particular, I consider two salient aspects of contemporary practice with mobiles--networking/communication, and picture taking--and explore technology designs that might exploit their potential for supporting related forms of…

Presents examples to illustrate that iteration and recursion are useful pedagogical tools that can be used in many areas of mathematics, make models traditionally taught in upper levels accessible in grades 9-14, and provide alternative problem solving approaches less dependent upon ready-made formulas.

Steiner's Porism states that if you can draw a connected ring of circles in the annular region between two original circles, the ring will be successfully completed no matter where you start. This paper explores how the TI-92 graphing calculator can be used to demonstrate Steiner's Porism and illustrate the main points of its proof. Inversion in…

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)

Uses the zooming technology of graphing calculators and certain graphing software to help middle school students extend their understanding of slope to curved graphs. (ASK)

This paper introduces a teaching unit on using spiral symmetry in a geometry course for secondary education majors. The TI-92 graphing calculator is used to exploit the exponential function to analyze the geometric topic of similarity and to study the derivative of spirals. The paper provides some procedures and programs to generate spirals using…

Describes two activities that involve thinking of slope as rate of change. Uses a calculator-based laboratory, graphing calculator, appropriate probes, and web sites to make the concepts of slope and y-intercept come alive for middle grade students. (ASK)

The Cabri programming language is a dynamic geometry software used all around the world by many of teachers, students, and researchers in mathematics. This paper presents examples of using Cabri and graphing calculators as a tool to practice mathematics and provides ways that mathematics could be approached, taught, and received in a way…

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…
