Modeling Hydrologic Systems in Elementary Science (MoHSES)

This project investigates 3rd-grade students' model-based reasoning about hydrologic systems and how teachers scaffold students' engagement in modeling practices. The research builds upon existing modeling frameworks to guide the development and integration of a long-term conceptual modeling task into the Full Option Science System (FOSS) Water module. The data collected from this project can help inform science curriculum materials development and elementary teacher preparation efforts designed to foster reform-oriented, model-centered elementary science learning environments.

Full Description: 

The Modeling Hydrologic Systems in Elementary Science (MoHSES) project involves research and development to investigate 3rd-grade students' model-based reasoning about hydrologic systems and how teachers scaffold students' engagement in modeling practices. The research builds upon existing modeling frameworks to guide the development and integration of a long-term conceptual modeling task into the Full Option Science System (FOSS) Water module. The participants in the study include ten 3rd-grade elementary teachers recruited from diverse settings. The team utilizes an extensive classroom observation system, in-depth interviews with students and teachers, and student artifacts to investigate the following research questions: (1) How do 3rd-grade students construct, use, evaluate, and revise conceptual models of groundwater systems to reason about geospheric components of the water cycle? (2) Are 3rd-grade students able to construct more scientifically-accurate models of groundwater cycling over time? (3) What instructional strategies do 3rd-grade teachers use to support students' model-based reasoning about groundwater systems?

This research can help build a foundation in model-based reasoning about complex global environmental and scientific phenomena in early learners. Investigations of elementary students' model-based reasoning about the water cycle, are largely absent from the literature. The data collected from this project can help inform science curriculum materials development and elementary teacher preparation efforts designed to foster reform-oriented, model-centered elementary science learning environments. This research also informs the development of learning progressions that account for elementary students' learning within a core component of the Earth Sciences.
