CSE is directing the research and evaluation activities for TERC and the Institute of Ecosystem Studies’ Biocomplexity and the Habitable Planet project. This project is developing a set of instructional materials that engages students, teachers, and their parents in the science of coupled natural human (CNH) systems. The inquiry-based investigations are designed around four cases in urban, agricultural, tropical, and polar systems, in which students address environmental management challenges increasingly confronted by society.
