This chapter explores the relationship between educational objectives and media, i.e., the nature and extent of the contribution which media and technology have made to the achievement of given objectives. It will not be concerned with a review of comparative effectiveness studies, nor will it conclude that a large number of "no significant differences" studies give evidence that "media" reach their objectives as well as some "other" means, method, or mode of instruction. A direct assessment of the effects of media on education is simply not feasible. When both antecedent and consequent variables are amorphous concepts, one can hardly speak with clarity and conviction about their relationship. Rather than struggle with a definition of "media"-a problem that Meredith (1965) considers so complex that some kind of taxonomy of "educational mediating systems" may be required-this chapter will be concerned with media that share certain characteristics.
