Do your students know how to make meaningful comparisons? Students must be able to examine similarities and differences within the critical content they are learning. They need to know how to use comparisons, classifications, metaphors, and analogies to generalize, draw conclusions, and refine schema. Based on the earlier work of Dr. Robert J. Marzano, Examining Similarities & Differences: Classroom Techniques to Help Students Deepen Their Understanding provides explicit steps for implementation and monitoring students' ability to examine similarities and differences. It includes adaptations for various student populations, examples and nonexamples from classroom practice, and techniques to avoid making common mistakes.
