Does the internet does more harm to students or good?

The internet has undoubtly revolutionised the world we live in now. From homes to schools, from adults to teenagers of all age. However, many people blame that the main reason that student are becoming more lazy, fail to hand in their homeworks in time and getting horid results. I myself disagree to this fact as some of the us teenagers are using the internet for different uses. Uses such as research on projects, reading the news online and if we do not have any projects, some of us are surfing the net for educational purposes.
Most of this facts are sadly true. Thanks to games and the messenger, teens nowadays are more focused on making friends or gaming and denying their work and studies. However not all teens do that. There are some who actually use the internet to do research on anything their interested in or even learning some new talents or even searching on the net to improve something such as their skills.
To me, the internet has become a great part in our lives also it might have also ruined students. However, its all up to the students will. Whether they choose to study or play. They may have homework but they choose to deny it and choose to use the computer for gaming purposes.
However as I said before some students actually surf the net to research on their projects, reading the news online and surfing the net for educational purposes. Therefore, it is not entirely the internet that does harm, it's the students choice. In my opinion more of them are not denying their work and studies because of the internet.
