Scientific modelling is a key practice in which K-12 students should engage to begin developing robust conceptual understanding of natural systems, including water. However, little past research has explored primary students' learning about groundwater, engagement in scientific modelling, and/or the ways in which teachers conceptualise and…

Elementary students should have opportunities to develop scientific models to reason and build understanding about how and why plants depend on relationships within an ecosystem for growth and survival. However, scientific modeling practices are rarely included within elementary science learning environments and disciplinary content is often…

Opportunities to generate model-based explanations are crucial for elementary students, yet are rarely foregrounded in elementary science learning environments despite evidence that early learners can reason from models when provided with scaffolding. We used a quasi-experimental research design to investigate the comparative impact of a scaffold…

Students' thinking should serve as the foundation of effective science curriculum and instruction. To promote science learning, particularly in the geosciences, teachers must attend to students' existing ideas about natural phenomena through the use of ''high-leverage'' instructional practices such as formative assessment. Elementary teachers need…

Previous research suggests that elementary teachers vary in their enactment of science curriculum materials and may not always engage students in substantive sense making. This mixed-methods study investigates elementary teachers' use of science curriculum materials to engage students in the scientific practice of comparing and evaluating…
