Let children learn to judge their work.    71   If corrected too much, he will stop talking. He notices a thousand times a day the difference 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.    72   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 and correct them for himself.    73   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. Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not.
If it is a matter of right answer, as it may be in mathematics or science, give him the answer book.    74   Why should we teachers waste time on such routine work?   75   Let the children learn what all educated people must some day learn, how to measure their own understanding, and how to know what they know or do not know.
