This booklet investigates the problems of evaluating the outcomes of science in general education and is directed specifically to educational objectives in the affective domain. Some insights are presented into the way the affective educational objectives of Krathwohl may be written in behavioral terms. The interrelationship of the affective, cognitive, and psychomotor domains is outlined, and the need for behavioral objectives in science is explained. The affective domain receives special treatment in terms of values and value systems, attitudes, interests, and motivation. Indicator behaviors for affective goals are presented along with a scheme for evaluating affective outcomes. Useful appendices include some examples of (1) affective goals in behavioral terms, (2) test items in the affective domain, and (3) evaluation instruments. (GR)
