No Teacher Is an Island: How Social Networks Shape Teacher Quality

Since the late 1990s, teacher professional development models have shifted from a focus on individual improvement to collaboration as a means to foster support, information, and resource exchange between teachers. Following this shift, researchers began to use social network research methodology in the early 2000s to reveal the ways in which informal relationships affect teachers’ practices. This chapter reviews current literature on teachers’ social networks and teacher quality to describe the ways in which social networks mediate teachers’ practices. It provides detailed examples from two studies on teachers’ social networks and suggests ways that scholars can incorporate the constructs of social capital and social networks into large-scale research on teacher quality.
