Corporal punishment was commonplace in schools throughout the civilized world up until very recently. Today teachers are forbidden on pain of termination from exercising corporal punishment on students. Has this contributed to a stronger learning environment and fewer disciplinary problems? A fair reading of the data would lead us to say no it has not. Corporal punishment would not solve all classroom problems, but so what? Neither does any other form of disciplinary action. It would correct much behavior that currently goes unpunished or only timidly so, as any student of a 1950's era Catholic school could tell you.
I'm currently Singaporean student, and caning is more or less acceptable in schools as a form of punishment forr serious offences (which are few and far in between). An example would be if a student was caught with drugs. Now, if he was a fully grown adult he would've been sent straight to the gallows. Caning is just a way to remind kids not to go astray. How do you think our crime rate is so low?
If you need to see a proof of why corporal punishment works, look to Singapore. Its students get some of the best exam results in the world. The big difference to other countries is the fact that the cane is still in use. Kids are the same the world over - they need boundaries.
Physical punishment doesn't work. Strong willed high spirited children can not be broken and the harder they try to control them the greater risk of failure. A loss of self accountability and pride in self, family, school and country are the root of our problems not a lack of paddles. End the poor me welfare state and maybe we will have a shot again.
Corporal punishment sort of worked in our past, but it was included in a system in which adults were more in control of their children than they are now. Children did misbehave in those days, but they knew they would get punished if caught, and if it was a teacher that punished them, then they would be in further trouble with their parents when they got home. Today's parents seem to believe it is wrong to physically punish a child, especially if it is some other authority figure besides themselves. Today's children can see that there is no clear line of authority, and punishments are usually weak forms of bribery to try to get them to conform. I'm not in favor of physical punishment, but parents and school systems do have to have some clear lines of authority and some kind of punishment that is effective.
Corporal punishment in a classroom setting would only make students feel isolated, if anything. It would not make them well disciplined and would likely lead to outrage and make students have worse issues with attendance and struggles with enjoying school. It would probably make them feel nothing more than embarrassment and humiliation.
