Interactionism
This group of sociologists see the social world in a different way to sociologists in the first two groups. They tend to focus on the individual, rather than "society", looking in particular at the way we create the social world through our behaviour (rather than looking at how society creates the individual).
From this perspective, society is not a living thing, but a fiction we create to try to make our lives orderly and predictable. Society, therefore, cannot force us to do anything, since it is only real for as long as we care to pretend that it is real. This pretence is helped by the fact that we lock ourselves into various social relationships (roles that involve rules and routines).
Social life is much less predictable from this point of view and the focus on individual lives and relationships places the emphasis upon investigating the way people live their daily lives as individuals and as part of wider social groups. The focus on what is called "small-scale social interaction" can be seen by comparing the way the different perspectives would look at the education system in our society.
