Children who want to study hard can study hard, no matter what class group they are in. Children who don't want to study hard will make trouble in classroom teaching. Therefore, in order to better provide a relatively good natural environment for children who study hard, the difference between key classes and non-key classes will appear. This is not to say that this difference is unreasonable teaching. It is said that everyone has their own interests and can't put all the staff in one room. It is said that the scholar is unreasonable to see the soldiers.
This is still very important in the regulations on the quality of students in colleges and universities, but personally, I think it is necessary to set up key classes. Because this is the best example of teaching students in accordance with their aptitude in ancient times, different teaching methods should be carried out for different students and teachers should guide them correctly in different ways, so many students are separated, which is also a faster way to let them use education.
If many parents think that the designated key classes are unreasonable, then you are a bit picky. If you have been a teacher, you will also see that such children are completely different on campus and at home, so parents who study think their children are good children. It's just that his main performance at home is that some children are particularly noisy on campus. However, children who generally study well are particularly delicate. Let's give a simple example. Let's put a child who studies mathematics and a child who studies politics and metallurgy for an hour. Then how do you ask the teacher to carry out his course content? Then, let's talk about putting a child who loves sports culture and a child who loves political metallurgy in the same classroom. Which student do you think the teacher will give priority to?
So this kind of key class is also because of faster classroom teaching. It's not that culture and education are unreasonable.
