If you give a person enough rope usually they will hang themselves with it. I think that connectivity to the internet can be a useful tool in a small group environment, however in a large group, in my experience, students tend to wander away from the task a hand either from boredom or from confusion. If you are going to give internet connection time to sudents as a tool I think the instructor should be equipped to view what each student, in class only, is looking at. This should deter the students from gravitating from the sites they "should" be at.
