Social Interaction

It is a way to have interaction on a classroom. Working in groups or pair group can help the students to have better communication between each other and to get to know one another a little bit better. It can break the barrier that some students have specially to people that come from different backgrounds talking about social and cultural differences.
In a class we can have students whose families live in a car and others who live on a three story house with four cars and more, and we can also have people from Asia, South America or Canada, so introducing this kind of activity can be a way to break the walls students have. Remember the movie that we saw last week "Freedom Writers" and the techniques the teacher used to get the group closer and closer.
On the other hand I think that some people work better by themselves and working in groups can be a bad experience for them. It also depends of the approach that the teacher use and the activities that the teacher creates for the students keeping in mind the students themselves.
