We conducted an evaluation of a computer-aided personalised system of
instruction (CAPSI) program in two undergraduate psychology courses. T
he computer presented students with short essay tests on the course ma
terial and arranged for students who had satisfactorily completed vari
ous assignments to help evaluate other students' mastery of those assi
gnments. On a questionnaire given at the end of the courses, most stud
ents indicated that they were satisfied with the use of the computer i
n the courses. Students most commonly cited convenience as the reason
for giving the courses a favorable rating. Also, students who did well
in previous courses tended to do well in the CAPSI courses.
