Nowadays, there is a lot of people who think that Students need to do their homework, besides others, people believe homework is not necessary. I think I agree that students should do their homework to help their life. On the one hand, It is acceptable that homework is maken stress for students. In the first place, everyday students always go to school to study from Monday to Saturday or even Sunday, for students it is really tired and it is long to made stress for them. Besides, after a long time studying at school if children need to do homework, adolescents don't have to relax time to play. In the second place, children always spend an hour, even more, do their exercise. This mean teenager can't spend this time to do a great number of creative activities. On the other hand, The first benefit that homework gives the students is that it helps them practice and practice at home more. Usually, an hour of 45 - 50 minutes in class is just enough for teachers to help students grasp the most important theories. However, if you only grasp the theories without practice, it will bring almost no benefit or efficiency. Therefore, assigning homework is to give students time to practice and practice knowledge presentations learned in class. Another thing that students can get when they are assigned their homework is time management skills. Why is that? Because homework is the part that students must complete after school is over. However, after school, students also participate in many other extracurricular activities, as well as have to do daily activities. Therefore, in order to ensure that activities are still going on normally, and still be able to complete homework before class, students must learn for themselves how to manage and organize their time. so that it is reasonable. For these reasons, I think daily homework is very necessary for students because it can help students in the future. To sum up, homework is good for students but if they don't know time management, homework will come to obsessions. Mọi người kiểm tra xem bài viết đã ổn chưa ạ
