Use Related Examples and Non-Examples to Explain A Concept

The video features Craig Barton discussing effective strategies for teaching concepts using examples and non-examples. He shares his journey from initially using definitions and single examples to realizing the importance of showing both what a concept is and what it isn't. Barton emphasizes three principles: mixing examples with non-examples, including boundary examples that challenge students' understanding, and using related consecutive examples to highlight critical features. He demonstrates these principles using the concept of triangles and mathematical expressions, showing how they help students better grasp the concepts by comparing similar and different cases. This method encourages deeper understanding and avoids misconceptions. Barton concludes by inviting viewers to adapt these strategies to their subjects and to share their experiences.
