Responsible and appropriate internet use by students

WOW... this is a good question... It is very difficult to do, a never ending struggle... the best I think you can do within the school setting is to inform/educate students on the law and their responsibility and consistently monitor that this is being done. Beyond that, we are not God and aren't able to see all and know all. One bit of advice, offer a lesson beforehand to inform students of their responsibilities, what is/is not allowed, and make them sign off that you did in fact inform them of this... this should help with teacher liability...
