Edgar Dale


Edgar Dale (April 27, 1900 in Benson, Minnesota, – March 8, 1985 in Columbus, Ohio) was an American educator who developed the Cone of Experience. He made several contributions to audio and visual instruction, including a methodology for analyzing the content of motion pictures.

Edgar Dale was born on April 27, 1900 in Benson, Minnesota. He received a B.A. and M.A. from the University of North Dakota and a Ph.D from the University of Chicago. His doctoral thesis was titled "Factual Basis for Curriculum Revision in Arithmetic with Special Reference to Children's Understanding of Business Terms." and is precursor for his later work with vocabulary and readability.

From 1921 to 1924, Dale was a teacher and the superintendent of schools in Webster, North Dakota. In 1924, he became a teacher at junior high school in Winnetka, Illinois, where he stayed until 1926.In 1928, Dale's interest in film led to a position with Eastman Kodak as a member of the editorial staff of Eastman Teaching Films in Rochester, New York for one year.

In 1929, Dale left Kodak to become a professor at Ohio State University. Dale remained a professor at OSU until his retirement in 1970.

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.
