I think we need student ordinances, They ara not mature therefore, They don't know how to control their personality, and They don't have a experience. they are puberty. therefore, they are very sensitive. they tend to defy their teacher at no reasons. and some of students are still rude and try to make a fun of teacher such as sexual harrassment , swearing , ignoring and even picking a fight and so on. In addition some students don't want to go to school, But If they get out of school, they are exposed from crime and they are uneducated therefore, They are hard to get a good job and they will be poor class. We are still difficult to get a good job, If we don't go to university in korea, This is a reality of korea.
That's because we have to enact new policy of school. we have to enforce rule. For instance detention, letter of apology , getting students to keep their both hands for long time. Instead we don't have to hit them. At present students can easily use a internet so they are exposed from bad web-sites. young students tend to imitate what adult do , We are concerned about a little chance they commit copycat crime. Student who commit crime don't commit only misdemeanor anymore. therefore we should protect them within school, we should come up with program they can come back to school. If they are too free to act like a adult, It's big problem , Some rich student will show off their cloths, cosmetics, motorcycle and electronics and so on.
it makes other poor student who can't buy them to be jealous of rich students, They are not mature so They can't control their mind yet.
In other words, Unless there exist strong rule of school, This is not school anymore. We can give them a penalty without touching them or consult with their parents. Until they become grown-ups, they have to have limitation of behavior. I agree that we have to prohibit physical punishment. However, We don't have to let them free to act like a adult.
