I learned the difference between conducting synchronous and asychronus discussions and when each would be more appropriate. Synchronus discussions should be limited by both number of attendees, topic and time and allow for some brief chit chat to help participants establish repoire with one another. A follow up summary would be a good idea to be email out on the main concepts. Asynchonous is more common and can be more in depth and cover all topics for the current week/module. I have always ensured that every student gets at least one individual response from me and a follow up one if they respond to my post. I use colors to denote an intial response vs. a follow up comment and find appropriate media or videos to ensure that students have an opportunity to hear/see/read the concepts in a variety of ways. We use Rubrics and even when I need to inform a student of a breach of netiquette or plagriarism, I always make sure I find something to compliment and encourage them with.
