If I made a language mistake, I will immediately corrected upon discovery. At school, once I made a language mistake, the teacher will help me correct. I think that teachers should give students the opportunity to correct their own mistakes. Because the teacher told the students can not be around forever, and help to correct the error, the students will certainly be out of the community, early learn to find their own mistakes is a good thing. You know, in the shade under the trees can not become a tree. Therefore, the children make mistakes, do not immediately correct the tension, I believe that children can correct themselves.
