This document provides an overview of Bloom's Taxonomy, which is a classification system used to define different levels of human cognition. It was created by Benjamin Bloom and covers three domains of learning - cognitive, affective, and psychomotor. The cognitive domain involves knowledge and intellectual skills and includes six categories from simplest to most complex: knowledge, comprehension, application, analysis, synthesis, and evaluation. The affective domain describes growth in feelings and attitudes and includes receiving, responding, valuing, organizing, and characterizing. The psychomotor domain involves physical skills and manipulation. Bloom's Taxonomy is used by educators to guide curriculum development, instructional methods, and assessment of student learning.
