This document discusses Bloom's taxonomy, a framework for categorizing levels of thinking skills. It provides an overview of the original and revised taxonomy, which changed the categories from nouns to verbs and emphasized higher-order thinking. Each of the six cognitive levels is defined - remembering, understanding, applying, analyzing, evaluating, and creating. Examples of classroom activities and assessment products are provided for each level to illustrate how they can be incorporated into lesson planning. The role of both teachers and students is described for each level.
