Technology Focus: Enhancing Learning of Limits of Functions with Dynamic Sketches
Cory, Beth; Garofalo, Joe
NCSSSMST Journal, v15 n2 p21-22 Spr 2010
After students have constructed a conceptual understanding of a mathematical idea, applying mathematical symbolism to represent and define the idea concisely becomes an easier task. In fact, Moore (1994) found that students "often needed to develop their concept images through examples, diagrams, graphs, and other means before they could understand formal verbal or symbolic definitions." A good example is the formal definition of the limit of function. Without a coherent pictorial model, students struggle to make sense of this definition, and it is no wonder when one considers its complexity. In this article, the authors present a tool they designed using "The Geometer's Sketchpad" which is a collection of interactive dynamic sketches which could be utilized to help students overcome hurdles involved in understanding the formal definition of the limit of function.
