At a time when children's cognitive abilities are increasing, middle school offers them fewer opportunities for decision-making and lower levels of cognitive involvement, but a more complex social environment. At the same time, numerous teachers have replaced the single classroom teacher and students often face larger classes and a new group of peers." American Psychological Association

At a time when children's cognitive abilities are increasing, middle school offers children fewer opportunities for decision-making and lower levels of cognitive involvement, but a more complex social environment. At the same time, numerous teachers due to departmentalization of faculty have replaced the single self-contained classroom teacher and students often face larger classes and a new group of peers."
