The author examines the effect of class format on student performance, time spent on homework, and instructor evaluations. The findings are unique and add to a limited body of literature. Each group comprised similar undergraduate students who received the same number of instructional hours, same assignments and were taught by the same instructor. Students in the one-day-a-week class performed significantly better than students in the two-days-a-week class. Students in the one-day-a-week class spent more time on online homework, although the difference was not statistically significant. Differences in instructor evaluation ratings were nominal.
