Studying at home by using technology such as computers versus Studying at traditional schools

As technology has developed, people are able to study using computers and smartphones in their house. As it becomes easier for people to touch computers, they are capable of getting a lot of information from computers when they do assignments. Some people say that students don't need to go to school. Instead, they are able to study material offered from teachers through the computers. They also save time that they would have spent going to school. Others think that when students go to school, because they get along with their friends, they can form good social skills. They can also improve their capacity as they compete, because students are able to inspire each other in the same class. I think that going to school is a better way.
There are two reasons why I think so.
First, when students go to school, as they meet their colleagues, so they are able to have an opportunity to from their social skills. As students can chat and have lunch together and play a game, that is, through the communication, they become friendly each other. But if students study in their houses, they don't have any chance to sympathize with each other.
Second, because students see a person who does his best to study, they will also determine to study hard like him. Even though a student tries to study hard in the house, if he or she falls out control of their mind [they let their mind wander]. Possibly then, he or she may fail. As students compete each other, they will advance .
Therefore, I prefer going to school.

[Very good.  I suggested the phrase "they let their mind wander"  - I think that is what you meant.]
