In this paper I analyze students' conceptual understanding of the quality of polynomial approximation. In particular, I analyze to what extent the interactive play with various methods of interpolation enables the students to build visual pictures that help understanding the formal mathematical statements. The role of the Mathematica software in…

This paper reports a study designed to probe the abstraction ability that US Algebra I students can achieve in moving the concepts rate of change and accumulation between motion and money contexts. The Algebra I students used the technologies motion detectors and Interactive Banking software during a replacement unit focused on slope, ratio, and…

This study tested the benefits of matching field dependent (FD) learners to an algorithmic method and field independent (FI) learners to a discovery method relative to mathematics achievement. It also attempted to discover if FD learners reacted more positively to computer experience than did FI learners. A total of 126 college algebra students…

Study of algebra students' response to availability of optional interactive computer graphing lessons analyzed responses of both users and non-users. Information sought included number of lessons completed, students' opinions of value and difficulty of lessons, whether students felt threatened by computer use, and relationship of gender and age to…
