Rural science teachers' collaboration, advice-seeking, and friendship networks: Social network analysis data

A matched teacher attribute dataset is also included. This file contains anonymized demographic, professional background, subject specialization, grade level assignment, regional affiliation, and participation indicators for the Technology Mediated Lesson Study (TMLS) professional development program. These attributes were used as node level predictors in ERGM and STERGM analyses examining how teacher characteristics and contextual factors relate to professional network development over time.

All identifiers were anonymized prior to public release. Numeric codes do not correspond to actual individuals, schools, or districts. Diagonal entries in the network matrices reflect occasional self-nominations recorded in the original survey data and were retained for transparency.

For most network modeling applications, these self-ties should be constrained to zero. The dataset is intended to support replication of published analyses on rural teacher professional networks and to facilitate secondary research on professional learning, teacher collaboration, and geographically distributed professional development.
