Social network research on teachers and schools has risen exponentially in recent years as an innovative method to reveal the role of social networks in education. However, scholars are still exploring ways to incorporate traditional quantitative methods of Social Network Analysis (SNA) with qualitative approaches to social network research. This article provides a mixed-methods model for researching teachers' social networks and an empirical example of the model in practice. The model incorporates a tri-modal coding approach that promotes data validity while uncovering network data that some SNA methods may overlook.
