I was checking out some of the links under thing #16 and I followed a link from "Using Wikis to Create Online Communities" to a wiki used for subject guides. This would seem to me to be a great use of wikis and I want to go on exploring the information on the wiki. However, I got sidetracked by a chat box on the subject wiki called "meebo" and I went off and created one for this page. You can scroll down and try it out at the bottom of the left column. If you click on "get meebo" at the bottom of the widget, you can create one.
This could be used for online reference or homework help with students. The LMT could post hours of online chat service on a wiki, blog or website and then chat with students and answer questions if needed. For now it is right next to the post about IM in the classroom. This could be one of the ways to use IM effectively in education. Something new to try!
