Born in the 1920s during the emergence of radio, schools of the air broadcast an impressive array of instructional programs for the classroom. These broadcast schools operated at the national, state and local levels; issued teacher manuals and learning materials; and offered enormous educational resources to students in both rural and urban areas. This work gives the history of 14 schools of the air, and fills an important gap in scholarship about American education and broadcast media. The book also assesses the successes and failures of the school of the air movement, and examines reasons for its demise.
