The article discusses the history, role, and use of teaching machines and how they can be employed effectively in foreign language instruction. The selection of programed materials, prior study preparations, and the expected conditioned verbal responses arising from machine use are briefly discussed. The advantages of teaching machines are seen as greater language fluency, increased audiolingual skills, repetition without drudgery, convenience of use, facility of self pacing, and the possibility of teaching more languages at different levels on all grade levels.
