the education of human beings

Hello,I,m from a planet very far from the earth and I can say that life here and life on my planet is quite different. For example how human beings educate their chidren it,s different, the children goes to a building that is like a house but huge, I think is call "school" and is full of children and they are separeted in rooms and in each room the children are of the same age more or less, every class has an adult person,(someone has told me that they are call teachers), who tells and explain things to the little people.
I came here just two days ago so I will have to investigate more about human,s behavior
