[Year 12 IT Apps] Disabling student web access

[Athena SPYRATOS]

Dear colleagues.
There are always some students in the classroom who surf the web during class when they should be doing their class work. Does anyone know of a simple method of disabling student access to the web during class time?
Regards,
Athena.
