1. Primary and secondary school students have poor self-control For them, learning is a very hard thing. Most students don't have such strong self-control. They sit in front of the computer or study with their mobile phones from morning till night. Therefore, students' learning effect cannot be effectively monitored.

2. Online teaching is basically indoctrination teaching, and learning needs constant interaction with teachers and classmates. Instilling teaching is not conducive to students' real mastery of knowledge, nor to the cultivation of students' innovative thinking.

Children will be interested in online teaching at first, but those are just appearances. They care about form, not content. After a few classes, if you find the form boring, you will lose interest in what you have learned, and you will be more tired of learning after a long time. Moreover, this form is not monitored (don't expect parents to monitor their studies effectively), which will make their weariness of learning more and more serious.

Online teaching will expose our next generation to electronic products for a long time, which is very harmful to children's health, especially to their eyes. Staring at the mobile phone for a long time will not only be nearsighted, but also form a cross-eye. Some students watch videos in bed and sofa, which is not good for the cultivation of students' self-discipline ability.

Some students have no internet at home, which makes them unable to study hard, and also causes unfairness to some extent.

I hope the relevant departments will not be taken in by unscrupulous businessmen, carefully analyze the advantages and disadvantages of online teaching, and don't harm the next generation for the so-called innovation.
