To give the simplest example, in the vast rural areas, there are more parents who can't teach their children, but they have not delayed their children from entering universities. Aren't there many families whose children have passed one or two or key universities?
To say that parents can't teach their children means that parents can't help their children like teachers, can't give them answers, and can't even give them answers to check.
But we must realize that learning is our own business and personal factors are very important. If we lack subjective initiative, then even the best external factors will not help. So, will parents? What do you need?
In school during the day, it is most important for children to master the relevant teaching content, understand the knowledge points explained by teachers in class, and review and consolidate in time after class.
Blaming others blindly is neither necessary nor self-blaming. What we can do is to guide children to cultivate their awareness, ask them to strictly demand their own learning, pay attention to lectures in class, review in time after class, and not relax.
In particular, educate children to have the concept of not being ashamed to ask questions. They can't escape when they encounter problems. They should face them bravely and try their best to solve them.
Ask more teachers at school, ask classmates after class, and ask other people around you who can help.
In short, the solution is always more difficult than it is. You can't make up for five by yourself, and the responsibility lies with others. Finally, you voluntarily give up studying.
In the final analysis, although parents can't directly provide academic help, they can also provide more education in other areas. Parents' life experiences are always much richer than their children's. Parents can always give their children better help, which can also give them correct guidance and help them become adults.
