Tangled in an Endless Web of Distractions

This Boston.com piece explores efforts at MIT to limit students' access to Internet distractions such as Facebook, YouTube and EBay.

In my mind, this story hits a root nerve in education:  Do we allow students access to these sorts of distractions and train them to resist, or do we remove the distractions altogether?

Let's face reality:  We all need to learn to control ourselves when we get out into the work world and keep things like social networking and on-line shopping in their proper place.  Where better to learn that self-discipline than in school?

What do you think?  Jam the wireless signals during class time?  During certain hours of the day?  Or help students like Katie find tools that allow them to monitor themselves?
