Running head: CENTRALITY AND EXPERTISE IN MATH SOCIAL NETWORKS Teacher Advice-seeking: Relating Centrality and Expertise in Middle School Mathematics Social Networks CENTRALITY AND EXPERTISE IN MATH SOCIAL NETWORKS 2 Cover Page Article Description: This study investigates how expertise and formal role relate to who is sought for advice about mathematics instruction, as measured by centrality, in 30 urban middle schools. Multiple analyses showed that: (1) coaches are more central than teachers who are more central than administrators, (2) teachers with greater expertise are more central, (3) teachers are more likely to nominate a coach if they perceive the coach to have expertise and be evaluative, and (4) administrators are rarely nominated as sources of advice about middle school mathematics instruction.
