ABSTRACT:
This is a teaching machine in which in a teaching mode, a question and its answer are displayed and the pupil sets the answer for that question into a number of settable memory units. In the examining mode, when the same question is displayed, the pupil sets in what he thinks is the correct answer, and that is compared with the answer in the memory units.
The apparatus can be reset for different questions.
