A 10-module computer-assisted instruction (CAI) program on study skills was field tested to determine its effectiveness with high school students, using 50 advanced seniors in a large Texas high school as subjects. The program consisted of a study skills pretest, the CAI modules, a notebook on study skills, and a posttest. The modules were programmed on a Commodore Pet microcomputer. Students in the experimental group were asked to complete one module per week during their free periods, while students in the control group were given a copy of the notebook and asked to go through the modules without the microcomputer. The module topics were time management, memory improvement, notetaking, textbook reading, examination taking, report writing, oral reporting, scholastic motivation, and interpersonal relations. Results indicate that the experimental group scored significantly higher than the control group on two of the subscales and on the total test. There were large differences among students in time spent on the CAI modules. The findings indicate that students who go through the CAI modules gain greater insights into effective study skills in the module's 10 focus areas and the use of the CAI in teaching study skills is supported. Suggestions for future research are included. (LMM)
