The document summarizes Revised Bloom's Taxonomy, which categorizes educational objectives along two dimensions: cognitive process and knowledge. The cognitive process dimension involves six categories of increasing complexity - remember, understand, apply, analyze, evaluate, and create. The knowledge dimension ranges from concrete to abstract and includes factual, conceptual, procedural, and metacognitive knowledge. Objectives specify a cognitive process verb and knowledge noun. The taxonomy is useful for classifying objectives and designing assessments.
