The study concluded that for online classes that range from 16 to 40 students, increasing class size as much as 25 percent does not significantly affect student grades, credits earned in the next session, or enrollment in the next session. The preliminary paper discussed the implications for the results, suggesting impact on cost savings for institutions with an online program with large numbers of students and classes. For instance, establishing class size limits of 40 students as opposed to 30 students could have positive financial implications through instructor compensation.  The researchers acknowledged limitations of the study, which was the sample of relatively small online classes.
