The world of knowledge is so wide that the class alone cannot bring everything into the grasp of the students. So teachers often give homework for students. But nowaday, teachers seem to give too much homework for students. In my opinion, Vietnamese high school students should be given less homework. we can't deny the benefit of doing homework. homework are given to help students to revise what has been done in the class and also the finish task set in school which the pupil couldnot finish on time.However, the large amounts of homework is not only help students understand the lesson well but aloso bing up the opposite results.if the is too much homework, students always have to worry about finishing it on time and getting bad marks if they don't finish it. Some teachers don't properly plan the homework task they give to to their students. the result is that students have to repeat tasks which they have already done at school. That isn't necessary for students. Too much homework in many subjects, students cannot concerntrate in doing them so the result of it can be decrease. for examble, if a boy have to write an essay while he has to concerned about his homework in maths, his essay can't get the best result.Therefore, teacher shouldn't give too much homework in too many subjects for students. If students are given less homework, they can have time for playing and taking part in some other activities such as volenteer work. these activities can bring up the same, even more benefits for students in learning. beside, there are some subjects require student's daily attention like biology and geography. Moreover, when students don't have to do too much homework, they can also have more time to hang out with friends.After relaxing, students are ready to learn and get better result. students have their own attitude and they need time for developing it. That is the reason why students should be given less homework. however, some other people don't think so. they believe that once students do lots of homework, they can understand their lesson well. they also think that homework is actualy the repeatition of what a child study in the class and that is good for children. I think, homework has its own benefit but too much homework isn't very well.students need time for doing other thing, not only homework. homework is important, but students should be given less homework. I believe that if students are given less homework, they can get the better result.
