• Firstly if children do not have teachers nearby, they can be very lazy and rely on their parents when they encounter difficult assignments, some of which parents can not handle it

• Besides, with specific subjects like literature, teachers can not grade students directly and explain errors to them clearly, and sometimes when students want to send essay through the internet to the teacher, they can have a problem with the connection that makes the quality of teaching go down

2) students do not have many chances to make new friends - lack of interaction - become more hestitate - hard to be friendly with other people

3) become nearsighted

+Online learning sources are plentiful and result in difficulties for a child to find the correct lessons to self-study effectively without a teacher's instructions.

+Studying at school is the best way for children to improve their social skills. The school's environment, where students can socialize and cooperate with peers, will help them to develop soft skills that will be obviously beneficial for them.

On the one hand, there are many factors that distract students from studying at home. For example, they could be distracted by television when they are study. The psychology of studying alone is also a factor that makes children feel bored studying online.

On the second hand, Poor network connection also affects the quality of lessons and children's learning

There are several reasons that I suppose school is necessary for students eventhough students can learn online at home.

Firstly, studying at home through internet's not as realistic as study directly. When students study face to face, it's easier for teacher to reach each person's seat and check their work as well as help them to correct their mistakes.

Otherwise, going to school for study help students to expand their social relationships. They will have a chance to meet lots of friends and easier to get along well with their friends.
