Grounding research-practice partnerships in educators' expertise can offer us insight into innovative approaches that schools are using to foster student SEL. Our efforts in facilitating the Boston Charter Research Collaborative (BCRC) educator convenings align with the Aspen SEAD recommendations for forging strong, mutually-beneficial partnerships, and yield important insights about novel approaches, resources, and uses of data related to students' social-emotional development. In our latest working paper from the Boston Charter Research Collaborative, we share lessons learned and recommendations for putting educators at the forefront of research-practice partnerships. We also share strategies and resources in use by BCRC educators from Roxbury Preparatory Charter School, Match Charter Public School, KIPP Massachusetts, and Boston Collegiate Charter School.
