An Observation

Students need face to face contact at some point during the learning process, especially with the instructor.  This can be achieved online through use of web cam.  There are a number of wonderful tools available for this including Skype, dimdim, wimba classroom, VoiceThreads, etc.  The visual helps students feel connect to the instructor as well as other members of the class.  With the visual and voice there comes a feeling of community.
