NYC Educator reprints his time-honored advice to new teachers on classroom management:
The best trick, and it's not much of a trick at all, is frequent home contact. It's true that not all parents will be helpful, but I've found most of them to be. When kids know reports of their classroom behavior will reach their homes, they tend to save the acting out for your lazier colleagues--the ones who find it too inconvenient to call. You are not being "mean" or petty--you're doing your job, and probably helping the kid. If you want to really make a point, make a dozen calls after the first day of class. Or do it the day before a week-long vacation.
This is not the first time I’ve heard this recently from a veteran teacher.
