These small-scale studies examine what occurs in classrooms from the perspective of both pupils and teachers. Researchers found that non-academic factors like speech, dress, and personality influence how teachers evaluate pupils, creating stereotypes. Setting students into bands or streams based on perceived ability can also lead to self-fulfilling prophecies, as students behave according to the labels they are given by teachers. Some studies also looked at how low-achieving boys form their own counter-culture that rejects academic success in favor of breaking rules and disruptive behavior.
