This course explores the meaning and scope of environmental education through the lens of environment-focused STEAM education promoted in the United States, with a particular emphasis on theory and practical application. E-STEAM integrates environmental contexts as the primary setting for STEAM education. The course will examine historical and philosophical perspectives on current topics in environmental education and the impact of school innovations. It will also study national and local models of environmental education and analyze their connection to contemporary issues of environmental literacy. Drawing from case studies across diverse educational environments, the curriculum includes campus lectures, online resources, field investigations, and hands-on research projects to help students develop the ability to design and plan environmental education content.
