Links Between Young Children's Behavior and Achievement: The Role of Social Class and Classroom Composition.

This article examines the association between attentive and aggressive behavior (at the child- and class-level) and individual child achievement.

Additionally, having more children in the classroom with low attention was linked with lower achievement gains, even for children who did not themselves demonstrate problem behaviors.
