B. F. Skinner was responsible for a different type of machine called GLIDER, which used his ideas on how learning should be directed with positive
reinforcement
In behavioral psychology, reinforcement is a consequence applied that will strengthen an organism's future behavior whenever that behavior is preceded by a specific antecedent stimulus. This strengthening effect may be measured as a higher fr ...
. Skinner advocated the use of teaching machines for a broad range of students (e.g., preschool aged to adult) and instructional purposes (e.g., reading and music). The instructional potential of the teaching machine stemmed from several factors: it provided automatic, immediate and regular reinforcement without the use of aversive control; the material presented was coherent, yet varied and novel; the pace of learning could be adjusted to suit the individual. As a result, students were interested, attentive, and learned efficiently by producing the desired behavior, "learning by doing".

Illustrations of early teaching machines can be found in the 1960 sourcebook, ''Teaching Machines and Programmed Learning''. An "Autotutor" was demonstrated at the 1964 World's Fair.

Edward L. Thorndike in 1912: "If, by a miracle of mechanical ingenuity, a book could be so arranged that only to him who had done what was directed on page one would page two become visible, and so on, much that now requires personal instruction could be managed by print".

Sidney L. Pressey in 1932: "Education was the one major activity in this country which has thus far not systematically applied ingenuity to the solution of its problems" (p. 668). He thought the machine he developed would lead to an "industrial revolution in education" (p. 672).
