An experiment in which secondary school French, German, and Spanish classes at a large comprehensive high school were conducted in three different kinds of classroom settings is described, with emphasis on student rating of machine-guided language practice. Classroom settings included (1) a conventional classroom with a few weekly half-periods in a broadcast or record-playback laboratory, (2) an electronic classroom, and (3) a control classroom where no tapes or equipment were used. A graph of the student ratings, generalizations about attitude trends during the year, and remarks about the results of other experiments with student attitudes and motivation are offered.
