Environmental education "is a process that aims to develop an environmentally literate citizenry" (NAAEE 2004). It is an effective way to engage students of all levels and has improved learning outcomes and achievement in science and other subjects (Lieberman and Hoody 1998). Worldwide, students report that schools are a key place for learning about environmental issues (PISA 2009). This article describes a field ecology course that was designed to engage all students in exploring environmental issues. (Contains 4 figures.)
