This "auto-tutor" from the 1964 World's Fair is very similar in concept to the "homework machine" we looked at from 1981. The photo above can be found in the Official Souvenir Book of the 1964 New York World's Fair.
The Autotutor, a U.S. Industries teaching machine, is tried out by visitors to the Hall of Education. It can even teach workers to use other automated machines.
