PUNCT, a computer-assisted instruction (CAI) course dealing with punctuation and usage was designed as a review course for college freshmen English students at the University of Texas. In 1971 forty foreign students registered to take PUNCT. This report summarizes the foreign students' reactions to the course, their suggestions for improving and expanding PUNCT, their experiences in the laboratory, and their progress in the course as revealed by personal interviews and computer user data files. The data indicate that foreign students can substantially improve their test performances in a short amount of time using this course. (MC)
