This document discusses using mobile devices to enhance environmental education and outdoor learning. It argues that effective environmental education with mobile devices focuses on using the local schoolyard and community as the learning environment. Students can use apps and tools on mobile devices to document fieldwork, analyze and present data, and connect their learning to the local community in emotionally meaningful ways. When used properly with activities centered around place-based learning and emotional connection, mobile devices can increase student engagement with and understanding of environmental concepts without replacing outdoor learning experiences.
