I had to take an online course last year. I found it interesting because the instructor had questions on the exams where we had to write essays on a certain topics. The online course I took before that, 3 years earlier, only consisted of multiple choice and True/False. I talked to the professor after the course just to make sure I understood the content, and one of his remarks was that student's essays where too short. The problem, I think, was that text boxes were ~10 rows, so the students would fill in those 10 rows and think they were done. Online learning is still new, but I think there are tons of improvements that can be made in order to make it a bit easier for everyone to understand.
