One way that teachers get the best out of kids? By expecting nothing less. When kids act up, they're told firmly that a teacher expects better and that's that. This way, kids learn to govern themselves based on the standard set by the stellar teacher. You can do the same at home by focusing on expectations, rather than disciplining poor behavior after the fact. Set concrete rules for behavior at home and be prepared to put your money where your mouth is when it comes to consequences, so your child knows you mean business.
