Appropriate Use Policy

I was reading an online article about whether we should still have parents sign an agreement giving their students permission to use the Internet and agreeing that their student will use it appropriately.

He argues that in many classrooms the Internet is now an integral part of the curriculum and no longer a supplemental resource. (http://www.edjurist.com/blog/acceptable-use-policies-becoming-a-relic.html)

He thinks that correct usage of the internet should be assumed (maybe placed in the student handbook) and we should punish students retroactively for bad behavior rather than having them sign before hand.

I think this is a pretty fair article and I agreed with most of it.

I was wondering how much teachers use the Internet for the bulk of their curriculum. I think that quite a few teachers still use it as a supplement. Any opinions?
