"Never have there been so many people grabbing at what they perceive as opportunities to use technology in education, and yet most have little understanding of the consequences of such applications, especially the changes in teaching methods and institutional structures that are necessary if technology is to have more than a marginal effect on learning. Ferster’s engaging, original argument—that knowing what happened when older technologies were used should be of great practical and academic value today—is one of the most exciting ideas I have encountered for a very long time. Teaching Machines adds a historical and conceptual perspective to the hoopla surrounding contemporary technology-driven innovation. I would love to see every teacher in training read this book."
