Recently, Wang Wenzhan, a professor at Tsinghua University, once again questioned the classic chicken-rabbit co-cage problem in primary school mathematics textbooks at the 10th annual meeting of the China Education 30 Forum, believing that this kind of problem is seriously out of touch with real life.
"I've lived to be 86 years old, and I've never seen a farmer keep chickens and rabbits in the same cage," Wang said. Do you see who puts real-life chickens and rabbits in one cage, isn't it all one cage and only one animal?"
Wang Wenzhan said, "The problem of chickens and rabbits in the same cage is only to solve the superficial problem, and it is not really used in life, and he also said to everyone that now children are just blindly trying to embarrass students, and do not consider whether primary school students really understand Olympiad. ”
As early as last year, Wang Wenzhan publicly stated that the problem of chickens and rabbits in the same cage is a very stupid problem, and such a mathematical problem is contrary to common sense.
According to Professor Wang Wenzhan's statement, in fact, in the school classroom, the knowledge learned is actually not very useful, so there is no need to learn?
Like the movement of celestial bodies in physics, all kinds of rotations, revolutions, etc., ordinary people can't solve any problems in life after learning these, so how to transform them?
For example, if you learn the functions, pi, calculus and other knowledge in mathematics, you can't use it in ordinary life, so don't you need to learn it?
Also, it can be said that almost more than 90% of the knowledge in other subjects in school is not used in life, so is there no need to learn it?
Of course, you can't think like this, learning this knowledge is to understand these things and expand your knowledge. Even if you don't need it in the future, you can still know what kind of theory this is talking about, and you can't just ask someone else and not know it.
In addition, it is through the acquisition of Xi knowledge that talents are selected for the country. You can't say that these questions are unrealistic, then you don't need to learn them, and that kind of thinking is not okay.
Students need to develop their brains through these strange problems, rather than saying that there are no such problems in life, so they don't think about it. You can't solve problems when you encounter them, but think about the problems that may occur in the future.
Chickens and rabbits in the same cage is one of the well-known mathematical problems in ancient China. About 1,500 years ago, this interesting question was recorded in the "Sun Tzu Sutra", which was described as follows: Today, there are pheasants and rabbits in the same cage, with thirty-five heads on the top and ninety-four feet on the bottom.
This question is originally a classic topic, and the ancients could find the fun of solving the problem through such a question, but in the eyes of this professor, it became unrealistic.
Of course, there is indeed a lack of real-life problem-solving courses in today's schools, and there is still a need to popularize more courses for solving life problems.
Most people disagree with this Tsinghua professor's view. They all think that he didn't pay attention to the key points, and what people pay attention to is not the chickens and rabbits in the same cage, but the conclusion and way of solving the problem.
Wang Wenzhan is 86 years old, so let's go home and take care of our days, so don't come out and toss around again, so as not to be angry and ruined. If there is a lot of useless knowledge in life, is there really no need to learn? What he has not seen is that what he has not seen does not exist, and is it unreasonable? Some people feel that learning is not interesting, but some people have solved the problems that exist in the world after learning, and this is the difference.
