Behavioral objectives serve several functions: (1) identify expected learner outcomes for a given lesson or unit of study, (2) provide a basis for selection and organization of materials and experiences for effective learning, (3) provide a systematic means for devising ways of evaluating student performance and (4) provide a means to identify those behaviors that children are already exhibiting prior to presenting a lesson designed to produce behaviors. When writing a behavioral objective, one must use a specialized verb limited to few interpretations. It is important to describe the situation in which the desired behavior is to be observed. The minimal acceptable performance for a given behavioral objective must be identified. Behavioral objectives can be written for different learning outcomes: (1) cognitive learning, (2) affective learning, and (3) psychomotor learning. (BR)
