Proof in Algebra: Reasoning beyond Examples
Otten, Samuel; Herbel-Eisenmann, Beth A.; Males, Lorraine M.
Mathematics Teacher, v103 n7 p514-518 Mar 2010
The purpose of this article is to provide an image of what proof could look like in beginning algebra, a course that nearly every secondary school student encounters. The authors present an actual classroom vignette in which a rich opportunity for student reasoning arose. After analyzing the proof schemes at play, the authors provide a hypothetical alternative ending that attempts to activate different proof schemes and engage students in the act of proving. (Contains 2 figures.)
