ABSTRACT
Lee Cronbach and I, along with many other students, were deeply influenced by Ralph Tyler's approach to educational evaluation. Though Tyler's ideas have been expanded in both his and our usage over the years, Cronbach's writings on evaluation (1982) still best reflect Tyler, both then and now. It thus is appropriate that this chapter examine the development and influence of Tyler's conception of behavioral objectives in educational evaluation, and to contrast this conception with that of others over the years. Cronbach's position with respect to this development will then be clearly seen.
