I just finished my masters in information science / library information science from Drexel University.
Most online programs appear the same - they use software called 'blackboard' and the professor posts assignments/syllabus for class.
The quality of the class really depends on the professor teaching it. I had one professor using notes from 5 years ago (was easy to see because he didn't change the dates on the papers), whereas, other professors were easily accessible after hours (which is REALLY important in choosing an online program.)
Online programs require self-discipline. You have to commit to meeting the class' requirements by a certain date/time. Also, group projects via an online class is borderline horrific. The memories still make me cringe. You are challenged with folks with different priorities and time schedules - group classes, online = horrific.
Overall, the Drexel University experience was good. Technically, the software worked fine and most of the professors were accessible.
I hope this helps.
