The best online class I ever took had this thing called "muddy buddies." Basically each week we were required to post questions about something we "didn't understand" from the assigned reading, and your assigned muddy buddy is supposed to answer. The genius thing about it is I would be reading the textbook and trying to find something I "didn't understand," but I didn't want to post a question that was too easy. So any potentially confusing part of the reading I would think about more closely until it was no longer confusing. Basically I was motivated to read everything closely because I was trying to find something that was actually hard to understand.
