The document discusses higher-order thinking and Bloom's Taxonomy. It provides an overview of Bloom's Taxonomy and the revised taxonomy. The revised taxonomy changes some of the original terms and places new emphasis on its use as a planning tool. It explores each of the six levels of thinking - Remembering, Understanding, Applying, Analyzing, Evaluating, and Creating - and how they involve different forms and complexity of thinking. Questioning by teachers and students plays an important role.
