You bring up an interesting point about introverts and extroverts and their preferences for asynchronous and synchronous discussion methods. I am wondering if these preferences have as much to do with personality types as they do with learning styles. The literature dealing with the benefits of online learning is full of references to the "shy" student who sheds that shyness in the online environment. Do you think the introverts will still prefer asynchronous discussions if the class is completely online rather than hybrid? Will they open up if they don't feel that others are watching them? Thanks for sharing your insights. :) Jane
