The document discusses Bloom's Taxonomy, which is a classification of learning objectives into six levels - Remember, Understand, Apply, Analyze, Evaluate, and Create. Each level represents a higher order of thinking, with Remember being the lowest level and Create being the highest. The document provides examples of questioning verbs that align with each level of thinking, and provides sample questions at different levels to demonstrate how questions can be used to assess someone's depth of understanding. The purpose of using higher-level questions is to make someone think more deeply about what they are learning and how it connects to prior knowledge.
