Hi Sherri,
Actually, I have found group projects to be very effective in the online environment, for many of the same reasons that they are used in the traditional classroom.
Building community in a virtual classroom is important and group projects help students to develop a sense of belonging. Sometimes, when students are geographically dispersed, the logistics of completing a group project present some challenges but, all in all, they are as useful online as in the classroom.
As far as the independent learner is concerned, he or she can glean much from the experience of a group project.
Thanks for sharing your thoughts :)
Jane
