A Historical Perspective from "a" to "c"
Edwards, Thomas G.; Ozgun-Koca, S. Asli
Mathematics Teaching in the Middle School, v15 n8 p458-465 Apr 2010
Evolving technology has played an important part in a common quadratic-function lesson. Having been mentioned repeatedly in numerous reform documents, a recurring lesson has involved changing the parameters in f(x) = ax[superscript 2] + bx + c and studying the effects on the graph. In both NCTM Yearbooks and NCTM Standards documents, technology is discussed and explored as a way to enrich quadratic function tasks. However, these authors will show how advances in technology have enriched these activities. Using quadratic functions as an example, this article describes how the evolution of technology has altered the expectations of students' understanding and critical thinking. (Contains 9 figures.)
