The document describes an action research project to extend engagement for teachers participating in the annual Sustainable Forestry Teachers' Academy (SFTA) in North Carolina. Based on surveys of SFTA participants and other environmental education programs, the researcher found that teachers prefer intensive, ongoing professional development connected to practice, including opportunities to network and share lessons. To address this, the researcher plans to implement an SFTA listserv, Edmodo online community, ambassador program, and reunion weekend to maintain engagement after the academy.
