there are so many information on the Internet

Nowadays,there are so many information on the Internet that you can find whatever you want,and it's not necessary for  students to follow their teacher.In my opinion,I don't agree with this point.
    Teachers could create a good environment for students to
learn something and if they don't pay attention to study,teachers could punish them and let them focus on it.It's
understandable that students always can't try their
best to books all the time because of the phones and computes without teachers,So if they follow their teachers to learn. the time they devote to their phones would be used on their
books.On the other hand,teachers could help student plan
their way to learn,which would be really helpful as it
could save a lot of time and make sure that you are always on the right way.As we all know that there are plenty of information on the internet and most of which could be wrong in
some case.But as teachers have so much experiences that they would choose a right way for students that the students could not only save so much time but also have an efficient way to learn something. 

However,sometime it would be better for students to study by themselves instead of following teacher,if they are not interested in what teachers said.Furthermore,if they still follow their teacher,they would neither have good grades,nor have their own strong points.There's a saying that the best teacher is always your interests,So if you 're not interested in what teachers said,you’d better learn something you are fond of on the internet at class,so that even though you don’t learn things from teacher,you still learn something that others don’t know. 

Anyway,as far as lm concerned,it’s efficient and better for students to learn things by following a teacher,they would not only create a good environment for you,but also give  you an efficient way that you can learn it fast.
