First, some advertising links or QR codes should not be added to the textbooks of primary and secondary schools.
I believe everyone knows one thing, that is, sometimes when we read this textbook, there will be a link or advertising textbook behind it. For example, when using Chinese textbooks, there may be links to compositions or Chinese textbooks. There is even a QR code.
Actually, I don't think this is right. First of all, the textbook itself is for children to learn, not for advertising. Secondly, if these other advertisements are always posted at the back, it will lead to involution to a certain extent, that is, children are under great competitive pressure now, and even links to some training courses will be printed in textbooks. I think this will aggravate involution to some extent. It is not good for children's growth.
Second, encourage all localities to buy some video materials that match the teaching materials according to the needs of students.
When we were young, we basically didn't have any video materials, and we all depended on the teacher to tell us. So what children can learn from a book is actually very little, because for example, a math teacher told us that we can only solve problems by students' imagination, but if we match some video materials, students can see how the graphics change more stereoscopically and intuitively.
So I think this is very good, and I hope that all localities can meet the local requirements of students. If the students in your place are rich, I think everyone should be equipped with this kind of video materials, but if this place is poor, I think some video materials can be used in some very necessary teaching materials, such as mathematics and geometry. Anyway, I hope everyone can do it.
