train students in scientific habits of thought. It has been pointedout before that it is of great importance that a student learnshow to apply the principles of physics to new problems. In-dependently of how we classify our aims, there are some veryimportant features, perhaps the most important, that cannotbe taught by the lecture method. Students learn how to thinkonly by thinking. They learn how to apply principles of physicsto new situations only by doing it. They need a great deal ofhelp and guidance in learning to apply these principles. Theyneed a method of teaching which can be used only in £>mall classes.

If a student is to receive this type of training that is so valu-able, not only must the class be small, preferably about fifteen,but the teacher of that class must use the "developing" method.He must not do most of the talking. He should not merely quizor ask students to "recite." He should expect the students todiscuss things. Where textbook assignments have been madetime should not be wasted duplicating what is clear in the text-book.
