Abstract
Ergonomic aspects of the design of a teaching machine system were studied. Standing operation by the teacher was considered to be preferrable. Push button switches with locking mechanism for pupils' selective responses, lamp coding as well as proper panel layout for both of the teacher's and pupils' panels and others were taken into consideration. The questions should be given by a projector from the back of the teacher, in order to ensure a bright room condition. Questionaire investigations showed that the pupils were of positive opinion for the machine teaching.
