I plan to suggest to my colleagues that we add an introduction page to our on line class to introduce ourselves professionally and more informally with a picture and something about our interests.
It may be fun to offer a place where students can introduce themselves but we do have to be aware of privacy concerns with our particular students. Perhaps we could offer a forum where students can do this but are not required to do so. Or perhaps we could have some sort of online "Bingo" kind of game where people put their names in an interactive document as an icebreaker.
