Drawing a Regression Line between Spaghetti & Basketball
Ozgun-Koca, S. Asli; Edwards, Thomas G.
Mathematics Teaching in the Middle School, v16 n1 p50-55 Aug 2010
"I liked to grab things on the graphics and see it first hand, see what we were doing on the problem. It makes more sense." These words were from a student who completed a series of lessons on lines of best fit. She made this comment after comparing a hands-on approach using a strand of spaghetti with a high-tech approach using a calculator. To give students meaningful experiences while studying regression lines, the authors designed a learning environment that accommodates "Bruner's three forms of representation." Bruner advocated a sequence of learning that runs the gamut from using physical materials to using symbols to teach mathematical ideas effectively. This article presents a regression activity using the TI-Nspire[TM] calculator and spaghetti. (Contains 4 figures.)
