Seoul and Gyeonggi office of education prohibited corporal punishment in schools in order to protect students’ rights. Since teachers are not allowed to hold the rods, lots of circumstances which fell down teachers' authorities are happening. In this situation, I believe the prohibition of corporal punishment neither brings positive educational effects nor increase of students' rights.
First of all, people should think about the real meaning of corporal punishment. Corporal punishment means 'giving physical pain to students in order to give educational messages'. Punishing students by objective judgement is a great way of teaching. Sometimes problems with teachers' personalities make corporal punishment turn into violence. However, this is much more acceptable than the situation that teachers are attacked by students. In other words, it is violent spanking by teachers which has to be prohibited, not corporal punishments.
In current condition, there is no replacement for corporal punishment. In other words, the most effective way of correcting students' bad behavior is physical punishment. The students’ mental is immature. So, they scared corporal punishment, which brings immediate pain. In the contrary, they are not sensitive to other alternatives such as points system, because they don't influence students immediately. Thinking like this will hard to change, and school without corporal punishment would become a chaos.
Considering the situations, banning corporal punishment would not expect a good results. Since it has no effective alternatives, inhumane and never close to the nature of the issue, banning punishment is not a good policy.
