Responses to questionnaires sent only to schools known to have language laboratories show that as of 1958, 240 colleges and universities and 64 secondary schools in the U.S. have such laboratories. Of 40 foreign languages, French, Spanish, German, and Russian are taught most frequently. Laboratory organization plans vary; they include classrooms, listening rooms, practice laboratories, mobile laboratories, and drill rooms. Representative scheduling is 30 minutes per session, four times a week, with no more than one session a day. For 91 colleges and universities that submitted cost data, installation costs ranged from under $1,000 to over $10,000, with yearly maintenance averaging $21 for 137 colleges and $67 for 19 high schools. Forty-six colleges and universities charge student fees averaging five dollars per semester. The aural-oral approach favored by language teachers is aided by audio-instructional materials which encourage studentparticipation and which feature several native speakers on one recording. While further research is needed to discover if language laboratories can alleviate teacher shortages, these findings indicate self-evaluation, and advancement. Appendices include the questionnaire, a sample description of laboratory design and functions, and a list of laboratories. (JO)
