Ruben,
I agree that we need to be very honest and upfront with students about the expected commitment to the course. I have also found that many students enter online programs thinking it will be an easy path to a degree, just to find out that it is as hard, or at times harder, than a traditional face-to-face course. The clearer we can be with our expectations, the less likely students will be to drop the course or fail the course because they had an unrealistic view of the course and commitment.
