This study investigated the independent and interacting effects of classroom-level embeddedness (i.e., hierarchical vs. egalitarian) and classroom density on the perceived popularity and social preference of aggressive and victimized 3rd-4th grade students (N = 881). A cohesive blocking procedure was used to compute embeddedness. Multilevel analyses indicated that aggressive children achieved much higher perceived popularity in hierarchical classrooms with high density. While children with high victimization scores were unpopular across classrooms, they were least unpopular in egalitarian classrooms with high density. Furthermore, aggressive children were more disliked in low-density classrooms, and victimized children were more disliked in hierarchical classrooms. Implications for educational management of classroom social structures are discussed. (Contains 1 table and 5 figures.)
