On the Internet, many people in China shared that when they were looking for change in a supermarket in China, they found it troublesome to give it to 10 yuan to get 3 yuan back, so they would give it directly to the store 12 yuan, which would make it more convenient for businesses to find 5 yuan. But this calculation is very convenient for us, but American waiters have to calculate the change for a long time. Therefore, when people in China talk about mathematics, they will complain that Americans are poor in mathematics.
The United States does not value the scores, calculations and exercises of mathematics, but explores and thinks about mathematics. American students' mathematical calculation is indeed far worse than that of China students, but domestic mathematics pays too much attention to problem-solving skills. We all pursue fast calculation in verbal calculation, mental abacus calculation and Olympic math competition, but children don't quite understand the truth. Moreover, many domestic masters of mathematics will not continue to study mathematics after being admitted to universities. In the United States, they pay more attention to solving problems than calculating, so there is a data on the Internet that the usage rate of calculators among students in China is less than 3%, while that in the United States is as high as 14%. Moreover, it is after college that it is an important period for them to study mathematics.
Secondly, American education has taught students in accordance with their aptitude.
They give ordinary children the most basic math education, but give those children who like math the most elite and highest level math education.
In fact, many States in the United States will give children who are about to graduate from high school a threshold for mathematics education. After this threshold, they can graduate from high school smoothly. Generally speaking, every regular high school has basic requirements for children's math level.
And this threshold, according to many people who came back from studying abroad, is probably the level of the first year of high school in China, and you can simply use trigonometric function.
As for those children who are interested in mathematics and talented, most high schools will provide them with special advanced placement courses, that is, AP courses.
American high schools are optional. After learning the basic compulsory courses well, you can take these courses at any grade, and you can take several courses without any problem. Therefore, these "schoolmasters" will learn these courses thoroughly within three years of high school.
It really takes talent to learn math again.
Von Neumann was able to calculate calculus at the age of eight.
Perelman, 16 years old, won the gold medal in the international Olympic competition with full marks.
Galois established the basic pillars of contemporary algebra and number theory at the age of 2 1.
Mathematics is a very gifted subject.
If the talent is poor, mathematics, whether good or bad, is basically meaningless. Basically, he will not become a great mathematician who will go down in history.
People with good talent will show their mathematical ability far beyond their peers from an early age. You can learn math easily.
Finally, I will tell you the truth.
According to the talent report of the American Mathematical Industry Association, foreigners account for 60% of the scholars in the mathematics departments of the top universities in the United States, among which China accounts for a large proportion. In the field of mathematics in the United States, foreigners account for half of the country. Every country is reforming its own educational methods, but no one is perfect, and no method is absolutely perfect, but we are basically learning from each other!
