ABSTRACT:
A programmable question and answer device having combined testing and teaching modes with multiple answer set programs. The device is comprised of a plurality of answer keys mounted on a housing, non-volatile, read only memory having a plurality of stored binary words parallelably outputted by a corresponding parallel input address code, control logic connected to the read only memory, program selector, and display. The program selector includes an activator strip having a coded pattern corresponding to a selected answer set. When the activator strip is inserted into the device, a particular program sequence is initiated. The display includes a display showing the accumulated score of correctly answered questions, next question number display, correct answer display when an incorrect answer key is depressed, and indicators to show when a question has been correctly or incorrectly answered. Due to the large number of different answer sets available from the read only memory and program selector, a student cannot memorize the answer sequences during repeated testing.
