Many educators question whether humans can be taught this way. But there is already ample evidence that in subjects that lend themselves easily to fragment learning, e.g., grammar, spelling, foreign languages, mathematics, automated teaching is far more efficient than the old-fashioned blackboard. New York's Collegiate School for boys tried teaching machines in math, found that 73 students completed in only two weeks an abstract-algebra course that usually requires two months. The Roanoke public schools used teaching machines on 34 eighth-graders-with no oral teaching and no homework-and in less than one semester...
...test teacher's stamina.) Sitting beside his "student" in a gadget-filled booth, which has 60-odd switches to pique the child's curiosity, the instructor also projects the chosen letters on a screen. After each half-hour typing session, the child prints the letters on a blackboard, soon works up to complete words and eventually to sentences...
Little Pigeons. A geologist's wife and mother of five, Teacher Joralemon began the school three years ago in her big Berkeley home, and used every minute of each 2½-hour school day to teach.

General Electric's Ralph Cordiner stood up and said: "Give us the money and stay out of our hair." Everyone else simply nodded. The next day a Marine courier arrived at the Special Projects office in the old Munitions Building and delivered top-secret orders...
With a stern hand, the teacher writes x+5 = 9 on the blackboard. If a youngster pipes up that the "unknown" is 4. he is shushed. The teacher must first demonstrate the rigmarole of subtracting 5 from both sides of the equation to get 4. Says Beberman: "The student had a notion of what a variable really is - and probably for the last time." Numbers v. Numerals. In his own elementary algebra course, Beberman first focuses on the semantic difference between a number and a numeral. One is a permanent concept, the other a mere name for it. A number...
