What are behavioral objectives? Why write and use behavioral objectives? Where do behavioral objectives come from? These three questions are answered in some detail in this paper; lists of selected references and resources and an annotated bibliography of "how-to" books accompany the text which summarizes much of the research dealing with behavioral objectives. The author states that behavioral objectives are "the first step in making more effective, systematic, and rational that most precious, most human activity--teaching others." (JY)
