Systems thinking is a fundamental geocompetency and developing student conceptualization of the Earth as a system is key to issues facing society. Additionally, systems thinking is a major topic for geoscience education research (GER), an endeavor that has engaged many members of the community for some time. This workshop will explore and build upon findings from a recent synthesis of work on systems thinking in the context of Earth systems (Scherer, et al., 2017), which identified four conceptual frameworks: Earth systems perspective, Earth systems thinking skills, complexity sciences, and authentic complex Earth and environmental systems.
