The document discusses Benjamin Bloom's taxonomy of educational objectives. It introduces the three domains of Bloom's taxonomy: cognitive, affective, and psychomotor. The cognitive domain deals with knowledge and intellectual abilities. It identifies six levels of complexity, from simple recall to evaluation. The affective domain concerns attitudes, values and interests. It identifies five levels from receiving to characterization. The psychomotor domain involves physical skills and coordination and identifies several levels of complexity. Bloom's taxonomy provides a framework to classify educational goals and objectives to help ensure congruence between goals, classroom activities and assessments across subjects and grade levels.
