Journal ArticleDigital resources are stored online in your NSTA Library.

In this article, the author describes how to challenge students with three intriguing questions and scaffolding techniques to help them develop a deeper understanding of light and vision. Through these surprising empirical experiences, students gain a much richer and more useful understanding of light and vision, which is very different from “understanding” the law of reflection and the principle of vision as isolated pieces of knowledge that cannot be applied to real-world contexts (Duckworth 1991).
