The document discusses Benjamin Bloom's Taxonomy of Educational Objectives, which categorizes learning objectives according to their cognitive complexity and provides examples. It outlines three domains - the cognitive, affective, and psychomotor domains. For the cognitive domain, it details Bloom's six levels of complexity from simplest to most complex: knowledge, comprehension, application, analysis, synthesis, and evaluation. It also discusses taxonomies for the affective and psychomotor domains and provides guidelines for writing clear and measurable instructional objectives and matching test items to objectives.
