In this e-book, 20 educators across the U.S. are trying to offer a fresh look at environmental education outcomes and their measurement. Outcomes measures are used in environmental education program evaluation. A number of resources support educators’ evaluation efforts. Yet educators continue to ask various questions related tooutcomes: What counts as outcomes of environmental education? How can their measurement be part of environmental education curricula? How to monitor long-term impacts of environmental education programs? To address these and other relevant questions, in 2013 the EECapacity national environmental education training program organized an online learning community of environmental educators, “Measuring Environmental Education Outcomes” (MEEO), whose exchange of ideas and collaboration resulted in this e-book.
