The study was to determine whether sighted college students in a self‐instructional course would learn more, and save time learning, while listening to tapes on variable rate controlled speech (VRCS) compressors as compared with listening to the same tapes on normal speed (NS) tape recorders. Time was mechanically recorded, and achievement was measured using on‐line‐computer‐administered post‐tests. Both the control group and the experimental group each consisted of 45 randomly selected students. Analyses of variance with repeated measures were performed on post‐tests of seven different taped modules and on mean time spent listening by both groups. Students who used VRCS compressors had an average time saving of 32 per cent and an average grade increase of 4.2 points on post‐test scores.
