Let's ask two questions first: What kind of students have entered key middle schools? What kind of students have entered key universities and famous universities? Depending on students' grades, students with good study habits and methods can maintain relatively stable grades and go further on the road to further study!
Screening students with high scores in exams! What kind of students can get high marks? Gifted, diligent and active ... are nothing more than students with excellent learning quality.
As for the excellent quality of students, should the credit be attributed to school education? Is it cultivated by the school, or is it discovered and screened by the school?
In the history of mathematics, there are many talented mathematicians who showed great talent in their youth, but the teachers in the basic education stage are usually not satisfied with them, so they entered the university with the help of higher-level content self-study! There is no doubt that abstruse mathematical problems play a screening role: people who are interested in mathematics, love mathematics and can keep thinking. And the teacher's job is to find them more.
Education and training
If "education is to screen students with excellent learning quality", is "excellent quality and learning quality" innate or can be cultivated?
After all, people are not sand in the river, but are destined to be "sand" and "stone" when they are born. Even at the moment of entering the campus, it is still full of variables: a naughty child with average grades does not mean that he can't go far; Clever and studious children are not always ahead.
Undeniably, teachers will have a far-reaching influence on some students, helping them achieve ideal results and enter ideal schools. In this process, the role of teachers is nothing more than changing students' learning attitudes, learning habits and methods. Especially in his youth, his "three views" are more easily influenced by external factors.
Screening+culture
Tsinghua University's "Training Plan for Leading Talents in Mathematical Sciences in Qiu Chengtong" is to start with "dolls", select high-quality seedlings, and then train them directly by mathematicians.
Even if it is not the cultivation of academic personnel, academic qualifications also play a role in screening. Some people even throw out the view that education is to achieve "class" stratification. Key universities mean state-owned enterprises, central enterprises and the top 500 in the world, which means high salaries; Ordinary undergraduate course means middle-income white-collar workers.
For a better future, everyone expects to get "high marks" and enter a "higher level". Great "pressure to enter a higher school" and fierce competition force parents and students to choose to increase their study time to alleviate their anxiety.
