The Taxonomy of Eucational Objectives, often called Bloom's Taxonomy, is a classification of the different objectives and skills that educators set for students (learning objectives). The taxonomy was proposed in 1956 by Benjamin Bloom, an educational psychologist at the University of Chicago. Bloom's Taxonomy divides educational objectives into three "domains:" Affective, Psychomotor, and Cognitive. Like other taxonomies, Bloom's is hierarchical, meaning that learning at the higher levels is dependent on having attained prerequisite knowledge and skills at lower levels (Orlich, et al. 2004). A goal of Bloom's Taxonomy is to motivate educators to focus on all three domains, creating a more holistic form of education.
