Investigating the Mathematical Process with Nonlinear Asymptotes
Principles and Standards for School Mathematics (NCTM 2000) emphasizes having students experience mathematics as mathematicians do and demonstrates that the Process Standards—Problem Solving, Reasoning and Proof, Communication, Connections, and Representation—are not simply means through which mathematics is learned and taught; they are also the manner through which mathematics is done. This article presents an abbreviated version of the musings and methodologies experienced by mathematics educators through a genuine problemsolving investigation. This account will investigate dimensions of an algebraic concept known to many high school students and show how these lead to an intuitive understanding of the limit in calculus. Readers will experience and come to a deeper understanding of the Process Standards as well as experience the necessity of using multiple representations to make and solve mathematical conjectures. To accomplish these multidimensional goals, the authors describe a chronological development of mathematical ideas among themselves and invite readers to reason along with them in their actual investigations.
