Calvin, I started the discussion about classes of 200 because I have seen some institutions offer online classes with 200 students as a money making venture. There was not a great concern about the level of interaction with the students. The course was focused on presenting the content; using traditional testing methods to evaluate the retention of the material; and minimal feedback to the students. My point was exactly what you mentioned...it would be almost impossible to provide the interaction and feedback that you get from a course of 15-20. An online course with 200 students is not the best model. However, have you seen the MOOC model? Herbert Brown III
