Demographic isolation and attitudes toward group work in student-selected lab groups.

Small group work has been shown to improve students' achievement, learning, engagement, and attitudes toward science. Previous studies that focused on different methods of group formation and their possible impacts mainly focused on measures of students' academic ability, such as GPA, SAT scores, and previous familiarity with course content. However little attention has been given to other characteristics such as students' social demographic identities in research about group formation and students' experiences.
