To investigate the television teaching of foreign languages in the elementary schools (specifically that of Spanish in the Detroit school system) based on the philosophy of FLES, the following factors were studied: (1) the historical background of foreign-language teaching methodology, of television teaching techniques; and of the emergence and development of FLES; (2) the history of Spanish television teaching in Detroit elementary schools from September 1957 through June 1964; (3) the roles of the television teacher, the classroom-viewing teacher, and the producer-director; and (4) materials including courses of study, television scripts, and annual reports made by administrators to the Detroit Board of Education. Although it was not possible to have control classes during the experimental period, and no true scientific data were available, the empirical evidence gathered indicated that children did learn to speak and understand Spanish when it was taught by the team of television and classroom teachers following the principles of FLES.
