This research draws on developments in educational research where learning progressions
are emerging as a strategy for synthesizing research on science learning and applying that
research to policy and practice, and advances in the natural sciences, where
interdisciplinary research on coupled human and natural systems has become increasingly
important. It focuses on the human systems that supply all of our essential goods and
services (i.e., food, water, transportation), which begin and end in the earth‘s natural
systems. In order to investigate what students know about how human actions affect
environmental systems, we developed assessments focusing on supply and waste disposal
chains. In addition, students were asked about a major environmental issue – global
warming. Assessments were administered to elementary, middle, and high school students
from rural, suburban, and urban schools. Results from this study provide insight into how
student knowledge of connections between human-engineered and natural systems varies
across grade level and context, which is essential if we are to teach students to be
responsible citizens and stewards of our environment.
