SELF-MADE RECORDS EDUCATIVE.--The educative value of the worker's making his own records has never been sufficiently appreciated. Dr. Taylor insists upon this procedure wherever possible.[6] Not only does the worker learn from the actual marking in of the spaces reserved for him, but also he learns to feel himself a part of the record making division of the management. This proof of the "square deal," in recording his output, and of the confidence in him, cannot fail to enlist his cooeperation. ORAL INSTRUCTION COMES FROM THE FUNCTIONAL FOREMEN.--The Functional Foremen are teachers whose business it is to explain, translate and supplement the various written instructions when the worker either does not understand them, does not know how to follow them, or makes a mistake in following them. ORAL INSTRUCTION HAS ITS FITTING PLACE UNDER SCIENTIFIC MANAGEMENT.--Oral instruction under Scientific Management has at least four advantages over such instruction under Traditional Management. 1. The Instructor is capable of giving instruction. 2. The Instructor's specialty is giving instruction. 3. The instruction is a supplement to written instructions. 4. The instruction comes at the exact time that the learner needs it. TEACHER, OR FUNCTIONAL FOREMAN, SHOULD UNDERSTAND PSYCHOLOGY AND PEDAGOGY.--The successful teacher must understand the minds of his men, and must be able to present his information in such a way that it will be grasped readily. Such knowledge of psychology and pedagogy as he possesses he may acquire almost unconsciously 1. from the teaching of others, 2. from his study of Instruction Cards and Systems, 3. from actual practice in teaching. The advantages of a study of psychology itself, as it applies to the field of teaching in general, and of teaching in the industries in particular, are apparent. Such study must, in the future, become more and more prevalent. ADVANTAGE OF FUNCTIONAL FOREMAN-TEACHER OVER TEACHER IN THE SCHOOLS.--The Functional Foreman-teacher has an advantage over the teacher in the school in that the gap between him and those he teaches is not so great. He knows, because he remembers, exactly how the worker must have his information presented to him. This gap is narrowed by functionalizing the oral teaching, by using it merely as a supplement to the written teaching, and by supplementing it with object-lessons. TEACHER MUST HAVE PRACTICAL KNOWLEDGE OF THE TRADE HE IS TO TEACH.--The teacher must have an intimate practical knowledge of the art or trade that he is to teach. The most profound knowledge of Psychology will never be a substitute for the mastery of the trade, as a condition precedent to turning out the best craftsmen. This is provided for by securing teachers from the ranks of the workers.[7]
