Environmental education researchers and policy makers acknowledge the need to act responsibly toward the environment. Yet, teachers do not always know how to help students translate environmental knowledge into sustainable action. This study examines the implementation of locally developed place-based education (PBE) curriculum for middle school science classes with the intention of promoting environmentally positive behaviors. Camera traps were placed near schools and teachers were provided with photographic data of urban wildlife to use during ecology lessons Through our grounded theory study, we found that teachers who perceived a curricular alignment and drew on curricular agency were willing to adopt and adapt the lessons for their classrooms. Those who did not implement the lessons either lacked curricular agency or perceived a misalignment of the PBE lessons and their school context. Our study informs environmental education professional development leaders, who, we argue, should allow teachers to first explore their own curricular agency and context. In addition, we encourage educators to explore how PBE can create opportunities to teach students about civic engagement.
