It has been my experience that online programs try to reach introductory course level students--those who might be the most vulnerable to time and focus constraints. Lately, I have seen some schools either 1) require an online orientation course, or 2) direct online courses to students with more established study skills--from sophomores through graduate level. Whatever can be done to debunk the illusion that online is "easier," will help. Some schools choose to include suggestions for "time on task" for activities.
