Alternatively if you have reason to keep a non-transparent proxy, you 
can use firewall settings (or iptables if it is linux) to block direct 
connections to common webserver ports from internal address except the 
proxy server.  That way if the student changes their proxy settings 
their web access will no longer work.  They will quickly stop doing it.
