The use of optional computer multiple choice quizzes has received a degree of popularity with students and has been shown to increase students' overall term grades. This statement seems justified based on the following results of this study. Over 70 percent of the students, over a five-year period, have voluntarily chosen to take the optional multiple choice quizzes. Second, measurable grade differences showed that the group of students who participated in the quizzes out-performed non-participants. Third, statistically higher correlations for non-participants between term grade and first hourly, and between term grade and final examination indicate that additional factors (perhaps additional learning) were influencing the participating groups' term grades. The questions of causality between optional computer quizzes and overall level of performance and the students' motivation for taking the quizzes remain unanswered.
