​Sugata Mitra is a professor of educational technology at Newcastle University in United Kingdom. He wanted to build a place where children can explore and learn on their own. They only had to use the resources from the worldwide.
Sugata Mitra is also an Educational researcher. His experiment Hole in the Wall, has shown us that children can learn without supervision or without a teacher who explains what’s this? They can teach themselves and each other if they are motivated by curiosity.  And the end of the experiments, they could see that people were playing around the computer and they were in a process to learn to use it.
Making this experience, Mitra and his colleagues went to New Delhi (North of India) and they did a hole in a wall next to an urban slum where they put a computer and a camera.  The camera filmed all the people was doing, their expressions, curiosity, etc.
In conclusion, this project demonstrated that, even in the absence of any direct input from teacher, an environment that simulates curiosity can cause learning through self-instruction.
In this video, we can obtain the conclusion that children discover by themselves and then, they teach other children. 
I think this process is wonderful, as well you can learn without being with another person. I believe learning things for yourself makes you learn better as you put more effort and interest and you do not feel you are under orders from someone.
