You don't want to play super teacher. Kid learned lesson, ok...next lesson, let him twiddle his thumbs. Wrong answer. And you don't want to go to the other extreme either. Push and push, like NCBL, until he passes out! This is a trick question. The teacher (everyone jump in!) does not have the sole responsible for the student's learning. The student, parent and teacher must work together as a team. Students are not vessels that we pour knowledge in. If that was the case, welll...that's another thread... salary for acheivement... we would be paid for how many kids we crank out. What if they fail? We are out of work? No...the kids must be responsible, and their parents. When you have done all you can do, (and... and this is very important) you have documented your efforts (telephone log, copies of extra homework, receipts for extra workbooks!) then you are safe to say to principal, "This is what I have done, this is what parent says, and this is his response. What would you suggest?" If you present your case to P this way, there is no other answer.. Results prove where student should go. Not your fault, his fault, parents fault. His work shows he is not ready to move on.
