This paper examines and summarizes the "Pierce-Gray Classification Model for the Cognitive, Affective, and Psychomotor Domains," a model developed for the classification of educational objectives. The classification system was developed to provide a framework that teachers could use as a guide when developing specific instructional objectives for students. In addition, it can be used to help achieve a degree of balance in the educational development of pupils. The Pierce-Gray model attempts to break down the barriers between the affective, cognitive, and psychomotor domains, and combines the three domains into one comprehensive, consistent, and interrelated classification system. The system is built upon the fundamental relationship between the domains, is consistent with current theory in all three domains, is easily understood and useable, and contains analogical relationships between the domains at each level. The model identifies six objective levels for each learning domain: (1) cognitive (perceiving, understanding, applying, analyzing, judging, and creating); (2) affective (perceiving, reacting, conforming, validating, judging, and creating); and (3) psychomotor (perceiving, activating, executing, maneuvering, judging, and creating). Each of these levels is in turn divided into two or three sublevels which are described in detail. (Author/JK)
