Environmental Education (EE) is a form of teaching that aims to increase students' ecological literacy, which is a person's overall understanding of the biophysical environment and its associated problems. We investigated the efficacy of online EE during a global pandemic on pro-environmental knowledge, attitudes, and behavior changes of fifth grade students. Our research showed online EE enhanced pro-environmental attitudes and behaviors as well as awareness surrounding environmental issues. Experiential learning, involving hands-on, activity-based lessons, were the most effective tools for teaching online ecological literacy.
