Comparison and Contrast

Frequent Use Strategy

The Comparison and Contrast strategy engages students in delineating, differentiating, and distinguishing information. The four connected strategies for Comparison and Contrast are comparing, classifying, creating analogies, and creating metaphors.

When using Comparison and Contrast, the teacher models how to analyze, qualify, and organize subtle and significant similarities or differences. Students identify similarities or differences between two or more items to understand how they are alike, equal, or analogous to each other.

Comparison and Contrast is not effective for comparing unlike, irrelevant, and dissimilar ideas or concepts. It is especially effective when the learning requires analysis to examine subtle similarities and differences between relevant ideas or concepts and results in a deeper understanding.
