Teacher. — The teacher may demonstrate the method manually to the worker, or by means of films showing synthesized right methods on the motion-picture screen. This, also, is a successful method of teaching those who speak a different language, or of explaining new work, — though it calls for a better memory than does the "working model," The model, however, shows desired results; the demonstration, desired methods.
Demonstration Method Chief Method of Teaching by Foremen. — The manual demonstration method is the chief method of teaching the workmen by the foremen under Scientific Management, and no method is rated as standard that cannot be successfully demonstrated by the teacher, at any time, on request.
Worker may Demonstrate Under Supervision. — If the worker is of that type that can learn only by actually doing the work himself, he is allowed to demonstrate the method under supervision of the teacher. [8]
Teaching Always Available Under Scientific Management. — Under Scientific Management all of these forms of teaching are available constantly. The instruction card and accompanying illustrations are given to the worker before he starts to work, and are so placed that he can consult them easily at any time during the work. As, also, if object-lessons are used, they are given before work commences, and repeated when necessary.
The teacher is constantly available for oral instruction, and the systems are constantly available for consultation.
