The authors take the point of view that the videocassette is an innovative, flexible, and potentially creative tool in the spectrum of educational technology. They distinguish between the cassette and the cartridge and offer advice, counsel, and examples of how both can be used innovatively in the various methodologies and philosophies of educational institutions in America. They explore the relationship of videocassettes to such aspects of education as the new media centers, informal and formal education, the comprehensive high school, open enrollment and the "new college," adult education, and special education for the gifted and the handicapped. Educators and the videocassette industry are cautioned that, while the future appears to be promising, the videocassette's success in improving educational opportunities is by no means assured; many problems, including the most pressing one of lack of equipment compatibility and industry standards, must first be solved.
