Edgar Dale (April 27, 1900 – March 8, 1985) was an American educationist who developed the famous Cone of Experience. He made several contributions to audio and visual instruction, including a methodology for analyzing the content of motion pictures. He was a professor of education at Ohio State University.
In 1933 Dale wrote a paper on how to effectively create a High School film appreciation class. This paper has been noted for having a very different view of adolescent interaction with films than that taken by the Film Control Boards of the time.
