The Slow-Motion Picture as a Coaching Device
Roy E. Priebe, William H. Burton · The School Review · 1939
THE importance of visual aids in instruction is increasingly recognized. Every day new visual devices are being purchased by school administrators and are being used by teachers who have little or no knowledge of the actual value of the specific aids selected. Motion pictures are being used by athletic coaches more extensively every year; The leading high schools, preparatory schools, and colleges spend thousands of dollars annually in the taking of motion pictures of athletic contests. Coaches are of the opinion that the showing of these films to the athletes who participated will bring about an improvement in individual or team performance. Coaches have observational evidence of the truth of this opinion but practically no objective evidence.
