The Teacher
The remarks in the first paragraph of the section under The Pupil, just preceding, apply equally here. Outside help is desirable, but simplicity in treatment must be maintained. Profound knowledge of a subject does not insure ability to restate that knowledge in simple terms. Better not have the profound knowledge displayed if it is going to leave the students in confusion.
The principle of home-made illustrations referred to above applies equally well to the section on The Teacher.
It is safe to say that each adult student in the class will remember teachers who have excelled in the points enumerated by Dr. Brumbaugh. The student should be encouraged to take a statement like that found in paragraph 4, page [182], and say to himself: "Which of my teachers was notably enthusiastic? How did this enthusiasm impress me? How did it help him in teaching great truths?" These observations may frequently need to be made quietly to the student's self. But they will greatly help him to master the laws of teaching.
