Although there have been great developments in motion picture technology, such as super 8mm film, magnetic sound, low cost color film, simpler projectors and movie cameras, and cartridge-loading projectors, there is still only limited use of audiovisual materials in the classroom today. This paper suggests some of the possible reasons for the lack of utilization of educational films. The author points out the advantages of films in classroom use, especially in the context of a systems approach to education. He discusses some of the work the Eastman Kodak Company has done in developing films for educational use. He also offers suggestions for ways in which to foster the use of films in the classroom. A reference list is appended. (JY)
