My classroom would be exactly as it is now. I would refuse to hit a student. Not too many years ago, I applied to teach in a private school. The principal asked me if I would administer swats when needed. I told him no and he said they wouldn't hire anybody that wouldn't spank the students. I thanked him for his time and left. Children need support, encouragement, and consequences, not physical punishment.
Life wouldn't be right because the more kids or anyone gets hit, the more desperate they are. Then, by then, they may start cutting their selves or kill their selves. :o Also, in the middle east, the teachers still do hit the students.
