Current research indicates that instructors find support for their teaching via membership in small social networks. The present study was conducted to further our understanding of these networks by looking specifically at the perceptions network members hold of each other in terms of similarity of beliefs and the value of their interactions. Results indicate that participants were more likely to perceive high rather than low similarity of beliefs with others in their network, and value was positively associated with perceived similarity. Implications for teaching practice and the work of educational developers are discussed.
