will be seen that this method furnishes him with more viewpoints from which he can consider his work.
Drawings, Charts, Plans and Photographs Means of Making Directions Clearer. — The Instruction Cards are supplemented with drawings, charts, plans and stereoscopic and timed motion photographs, — any or all, — in order to make the directions of the Instruction Cards plainer.
Stereoscopic and Micro-Motion Study Photographs Particularly Useful. — Stereoscopic photographs are especially useful in helping non-visualizers, and in presenting absolutely new work. The value as an educator of stereoscopic and synthesized micro-motion photographs of right methods is as yet but faintly appreciated.
The "timed motion picture," or "micro-motion study photograph" as it is called, consists of rapidly photographing workers in action accompanied by a specially constructed chronometer that shows such minute divisions of time that motion pictures taken at a speed that will catch the most rapid of human motions without a blur, will show a different time of day in each photograph. The difference in the time in any two pictures gives the elapsed time of the desired motion operation or time unit.
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,
