Let children learn to judge(判断) their own work. A child doesn’t learn to talk by being corrected all the time. If he is corrected too much, he will stop talking. He notices a thousand times a day the differences between the language he uses and the language others use. Little by little, he makes the necessary changes to make his language like other people’s.

In the same way, children learn to do all the other things without being taught—to walk, run, climb or ride a bicycle. They compare their performances with those of more skilled people, and slowly make the changes. But in school we never give a child a chance to find out his mistakes and correct them himself. We do it all for him. 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 work out with the help of other children if he wants it.

If it is a matter in math or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such daily work? Our job should be to help the children when they tell us that he can’t find the way to get the right answer. Let the children learn what all educated persons must learn, how to measure(估量) their own understanding, how to know what they know or do not know.

Let them get on with this job in their ways. School teachers can offer help if they ask for it. Some parents and teachers are worried that the children might fail to learn something that they will need to get in the world. Don’t worry! If it is important, they will go out into the world and learn it.

This year, who “entertained us, challenged us and changed our world”? Absolutely(毫无疑问地), Jeremy Lin, an Asian-American NBA rising star, is one of those people. On April 18, TIME Magazine named him one of 2012’s MostInfluentialPeople in the World.

Lin, 23, is not just a good basketball player, but also a graduate of Harvard University, one of the best universities in the world.

“Lin has broken the idea that one can’t be a world-class athlete on the court and an excellent student off the court at the same time.” US Education Secretary Arne Duncan wrote in the TIME article about Lin.

At 191cm, Lin isn’t especially strong, compared with other point guards (组织后卫) in the team. What makes Lin stand out from other players is his hard work and never-give-up spirit.

“I know how the team works. I may not get an opportunity, but I’m just going to put it all into this and see what happens.” Lin once said. He kept arriving early, leaving late, practicing hard and learning from other experienced players. Finally, when his opportunity came, he started to shine.

“He earned(赚得) it.” Duncan said. “He lives the right way, and he plays the right way. He works hard and stays modest. He sets a good example for young people today. ”
