Why are only 25 participants admitted in a cohort?
In any format, classroom-based teaching or online courses, it is widely recognized that very large class size inhibits interaction across the whole class. A substantial part of the value in the MBA comes from interacting with colleagues who are thinking about how to apply the class material to their own organizations. Thus, if interaction breaks down, the whole class suffers. Research shows that performance in smaller classes is better online, and participants themselves are less satisfied and feel that they learn less with large classes. Many business educators with experience teaching web-base classes feel that optimal class size ranges from 20 to 30. Why does quality decline if class size gets too large? In the online environment, discussion and interaction is mostly in the form of written documents. Suppose each participant writes and posts about 75 lines of written material (roughly 2 single spaced pages) about the weekly assignment. This amounts to 1875 lines per week to read in
