The teacher's ability to stimulate and to work with each student largely determines the value derived from a course by the student. The contact of teacher with the individual student is more difficult to effect in large classes (50 students or more) than in small classes. In the large classes a restraint and formality may prevail that are lacking in groups of 20 students or fewer.
