I think you would want to be able to create or modify user
accounts in bulk lots (e.g class groups). For that you'll
want to learn how to use the LDIFDE utility or the CSVDE
utility.
Check out this page for LDIFDE...
http://support.microsoft.com/?kbid=283791
or to use CSVDE.exe to import CSV format files into AD.
See here....

I'd say You'll also want to use Group Policy extensively
to lock down what the students can and cannot do. You are
talking about the best hackers in the world here (just ask
them).
I'd use computer image management (Ghost etc.) and if you
can afford a server for it and PXE compliant workstations,
use RIS to redeploy workstation images in the event of
them getting trashed.
have a look at this powerpoit file for a discussion on
workstation management practices..

I hope this has given you some new ideas.
