This document provides a brief history of teaching machines and automated education. It includes quotes from Thomas Edison in 1922 who believed that motion pictures could revolutionize education by achieving 100% efficiency compared to 2% from textbooks. Characteristics of early teaching machines are described as breaking content into small testable units, providing immediate feedback, and allowing students to move at their own pace. The document also quotes B.F. Skinner about using reinforcement techniques to precisely control behavior and learning. Finally, it quotes Sidney Pressey advocating for an "industrial revolution" in education using technology to modernize inefficient procedures and free teachers and students from drudgery.
