This dissertation formulates and investigates a set of hypotheses about the mechanisms that support the successful implementation of partnership models in K-12 public education. The research study is conducted within a rapidly growing type of partnership model known as "teacher residencies," in which a partnership between a higher education institution and a K-12 school district is used to train and develop novice teachers. A typical residency program relies on mentors, supervisors, and advisors to support residents' development. In this research, we draw connections from the teacher residency model to a set of relevant theories in management sciences and psychopathology, which have not previously been explored in this context. To understand the function of relational ties between individuals in the residency program, we apply Relational Coordination Theory, which posits that alignment of goals, sharing of information, and effective communication strengthens interdependent work processes. We use network science tools from psychopathology to generate visual models that display the complex interplay between role relationships and performance outcomes for residents. Our analysis indicates that increased relational coordination positively predicts performance outcomes for residents, and that this occurs through an interdependent, non-uniform network structure. These results confirm, empirically, that an interconnected ecosystem of relational ties, rather than an isolated set of relationships, act collectively to influence outcomes within the network. Our findings suggest that these "networks of productive interdependence" represent a mechanism through which effective partnership models can be implemented, and that practitioners and policymakers must invest the necessary resources in order to successfully cultivate and nurture these networks.
