Technology Focus: Multi-Representational Approaches to Equation Solving

Most mathematical functions can be represented in numerous ways. The main representations typically addressed in school, often referred to as "the big three," are graphical, algebraic, and numerical representations, but there are others as well (e.g., diagrams, words, simulations). These different types of representations "often illuminate different aspects of a complex concept or relationship," and each has its own features, advantages, and limitations. For students to have a conceptual understanding of functions, they not only need to understand each representation on its own, but also need to be able to link different representations meaningfully. Solving equations using a function approach, with different representations, can help students learn to better connect representations. In this article, the authors present two sample activities they use with their pre-service teachers to help them think about teaching with multiple representations. (Contains 2 figures.)
