Summary and Recommendations
Although a great deal of research has been done on programming for preschoolers and classrooms, there are major gaps in the literature. One such gap is in the effects of video production by students. Another area in which the research is confusing is that of newer programming genres for which it is difficult to compare findings. Contemporary varieties of advertising on television also present a very complex topic that warrants more research. Greater attention should be paid to the effects of genre differences and program formats, as well. It is important for researchers to investigate the interaction of the content and form of programming with other variables.
