The document discusses Bloom's Taxonomy, which categorizes questions and thinking into six levels from lower to higher order thinking skills: knowledge, comprehension, application, analysis, synthesis, and evaluation. Examples are provided for each level with common verbs used to form questions and potential student activities. Questions and activities become more complex as the levels increase, moving from simple recall of facts to more evaluative thinking and creation of new ideas. The taxonomy provides a framework to help teachers construct questions that target different cognitive skill levels.
