" The best type of instruction is individual instruction. A course where one teacher instructs one pupil is clearly by far the best type of course. It is only under such conditions that human potentialities can develop to their greatest degree. It is clear that the formal school, characterized by classes in which one teacher instructs many children, is an immensely inferior system. Since each child differs from the other in interest and ability, and the teacher can only teach one thing at a time. "
