Why does the country have a double reduction policy?

First of all, what is the double reduction policy? It is to effectively reduce the excessive workload of students in compulsory education and the burden of off-campus training. Heavy homework will make students not take their homework seriously, which will lead them to take extreme measures to complete their homework. For example, buying homework or copying homework will make children not go behind at first, and can't keep up with the teacher's rhythm, which will lead to weariness of learning. Think about it. I used to copy other people's homework in junior high school. Only when there is less homework in high school can you have time to take every problem seriously. If you don't, you will also look up information and watch videos to learn, and you won't ignore it as before. Secondly, sleep is also very important. If the quality of sleep is not up to standard and you feel groggy in class, you will still not understand what to learn.
