Mitra found in some of his experiments that groups of children with a computer learned better than a single child with a computer. why might this be? what benefits do groups offer? what role might social media play in this?

Mitra found it better because students or people learn better in groups rather than being single.  

Explanation:

Group learning is always better than learning rather than learning single. People in group can discuss on a certain topic which they learn. The discussion learning is helpful in solving greater ability to view situations from others' perspectives.

Students can discuss their doubts without any fear. But when it comes to media, the role of the media is spreading information on a large scale. Media is a one such platform which provides information more people at a same time. People who are in group can discuss the news or information in details and clear their views on that piece of information.
