The document describes Bloom's Taxonomy, which is a classification system used to define and distinguish different levels of human cognition. It provides three domains - cognitive, psychomotor, and affective. The cognitive domain refers to knowledge and intellectual skills. It includes six levels from basic recall to evaluation. The psychomotor domain includes physical movement skills ranging from perception to complex adaptation. The affective domain focuses on attitudes, appreciation, values and motivation with levels from receiving to characterizing. Bloom's Taxonomy provides a framework to organize educational goals and objectives to clarify expectations and alignment between teaching and assessment.
