text: One of the versatile things about having prerecorded class lesson or set times to listen in is a great way to let material sink in. Not only does it keep people engaged in the conversation, but it allows slower readers, or anyone needing to really get a concept, to re listen to discussions. To continue, having a centralized place where students go to find work and lessons prevents confusion of assignments. I've had personal problem in the past where I didn't fully understand what was being taught, but we just kept moing on. If I had that class online, I would have the option to go back and learn what I missed.
