Largely underutilized in educational evaluation, Social Network Analysis is powerful research methodology that can be used to improve communication and knowledge creation among teachers, and to scale instructional innovation throughout a school. In this presentation, we reported how SNA has been used in the evaluation of teacher collaboration, specifically as a key component in the implementation of the Teacher Collaboration Improvement Framework (Gajda & Koliba, 2008). Session included evidence on how evaluators can use SNA to generate information in creative formats that school principals and K-12 superintendents (primary evaluation stakeholders) can use to: 1) inform decisions about how best to structure, strengthen, and support school and district-level teacher collaboration, and 2) empirically examine the relationship between teacher collaboration, quality of instruction, and student achievement. #SocialNetworkAnalysis #2011Conference #Prek-12EducationalEvaluation
