The document discusses Bloom's revised taxonomy, which is a framework for categorizing levels of thinking and learning. It describes the six cognitive levels - remembering, understanding, applying, analyzing, evaluating, and creating - from simple to more complex thinking skills. The revision changed the categories from nouns to verbs to better reflect thinking as an active process. It also reorganized and modified some categories to make the taxonomy more applicable for teaching, learning, and assessment. The framework helps teachers write learning objectives, plan curriculum, ask effective questions, and align activities with standards at different cognitive levels.
