It's up to the parents to set there children's priorities, and make sure they stick to them. In my house there is nothing more important in my children's lives than there schooling. I have pulled the plug on the xbox for months at a time. I've taken the phone, the ipod, not let them do things, whatever it takes because of grades and my knowing that they were not trying there best. And they are well aware that I can and will continue taking until the grades improve. I geuss if it came down to it and I thought it would help, public humiliating would be somewhere on the list, but it's never came close to that.
