Math Problem 3 of Grade One Brainstorming Test "Brainstorming"
"A person went to a place, he used the same means of transportation to come and go, but it only took him an hour to go and two and a half hours to come back. Excuse me, why? " This is a Chinese question for children who studied in the first grade of primary school last semester.
The reporter asked colleagues, middle school students, college students and even university professors to answer why, but none of them answered correctly. It turns out that this is a punctuation test, and there is a pause between "two and a half hours" in the title, so that "two and a half hours" add up to an hour.
Zhu Zhengzhou, president of Wuhan Jiyuqiao School, said, for a child who is only in the first grade of primary school, is our education a bit more and more obsessed with such a topic?
"People who have read middle school probably remember that there is a math problem that is seriously divorced from the reality of life."
Zhu Zhengzhou said, for example, there is always a tendency in junior high school mathematics: "A swimming pool has a water inlet and a water outlet, in which it takes X hours to fill the swimming pool with the water inlet and Y hours to drain the swimming pool with the water outlet. How many hours can two nozzles be opened together? " Topics like this.
"Will there be such a scene in life?" Zhu Zhengzhou said that the questioner did not connect the topic with life, but only paid attention to the knowledge points and "mechanically copied" things that were divorced from life.
"There are still some problems, even violating and divorced from morality and ethics." 2 1 Xiong Bingqi, vice president of Century Education Research Institute, said for example that a university had a final exam and asked candidates to write a list of students who usually like to be absent from class.
"Isn't this for students to expose each other?" Xiong Bingqi said that teachers can try to innovate teaching methods and students' exams, but innovation must have a basic ethical bottom line to avoid students' moral and ethical troubles.
The following two "god questions"
Still a little reliable.
"Of course, although some topics look shocking, they are really high after careful reading. This kind of topic should be advocated. " Zhu Zhengzhou said.
In the just-concluded final exam in Wuchang District, the reporter saw such a question on the math test paper of the third grade of primary school: "The time required for smiling mother to cook is as follows: rice washing for 3 minutes, porridge cooking 10 minutes, vegetable washing for 6 minutes and vegetable cutting for 6 minutes. Can I ask my smiling mother to spend at least () minutes to finish these things? "
"This problem is not a simple four-time addition, but uses arithmetic and overall planning. Students should not only learn simple calculations, but also learn how to do housework. This is a typical' life mathematics'. " Zhu Zhengzhou said. The answer is 15 minutes, because porridge 10 minutes can be divided. )
On this set of test papers, there is another topic that impressed the reporter. "Which of the following weights is close to 1 ton?" The four options are 10 bottle of mineral water, the weight of 40 students, 1000 coins, 1 train skin coal.
Obviously, this problem can not be solved by simple addition and subtraction, and children need to judge by what they have learned in life.
