Passage 1
Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time: if corrected too much, he will stop talking. He notices a thousand times a day the differences between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people’ s. In the same way, children learning to do all the other things they learn to do without being taught——to walk, run, climb, whistle, ride a bicycle——compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes for himself, let alone correct them. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to. Soon he becomes dependent on the teacher. Let him do it him sel
A. They give children correct answers.
B. They point out children' s mistakes to them.
C. They allow children to mark their own work.
D. They encourage children to copy from one another.
