This document provides an overview of Bloom's Taxonomy, a framework for categorizing levels of thinking skills. It details the original taxonomy developed in 1956 and the revised version from 2001. The revisions updated the taxonomy to better reflect 21st century work. The taxonomy categorizes thinking into six levels - remembering, understanding, applying, analyzing, evaluating, and creating. It encourages teachers to scaffold lessons to help students develop higher-order thinking skills. The document provides examples of how to incorporate each level of thinking into classroom lessons and assessments.
