"The results of research on the effectiveness of four alternative instructional media are reviewed: traditional classroom instruction, instructional radio, instructional television, programed instruction, and computer-assisted instruction (CAI). It was concluded that students learn effectively from ... all these media; relatively few studies indicate significant differences between media in effectiveness. Future research should focus on four areas: 1) determine if programed instruction and CAI can be shown to save instructional time over a longer period and with a higher percentage of students; 2) investigate long-term effects of instructional technologies on students' motivations; 3) investigate the long-term effects of the individualization and privacy made possible by some of the technologies; and 4) future investigations should consider more imaginative uses of new technologies instead of using technology to provide a simulation of some traditional method."

"The average student is likely to learn about as much from a television class as from ordinary classroom methods — There is no significant difference between the two methods — Televised instruction has been used with greater success in the grades than in high school or college, in elementary sch ... ool children are enthusiastic over television classes — In the two other cases, high school and college, students are equivocal or in some cases unfavourable — Is there any kind of student who profits more than other kinds from instructional television? — Does size of class make any difference in learning from instructional television? — What we know and must need to know about learning from instructional television? — Such are the questions the author deals with in this chapter."
