Water is one of Earth's fundamental natural systems. It is crucial to foster water literacy in today's global citizens, particularly through formal education. The purpose of this research, in parallel with a study focused on human dimensions of water systems (Mostacedo-Marasovic et al., in press), is to examine water-related K-12 standards for…

Groundwater is a critical component of the global water cycle and standards-based topic within science education. However, students articulate an array of ideas about groundwater systems, including their natural and human elements. One way to support students' learning about groundwater systems is through the use of data-driven, computer-based…

Developing understanding about the Earth's climate and the phenomenon of global climate change (GCC) is essential for all students, our future citizens and decision-makers. Recent implementation of the Next Generation Science Standards (NGSS) has intensified the focus on teaching and learning of the Earth's climate and GCC in formal learning…

In this mixed method study, we analyse the effectiveness of two pedagogical approaches -- one model-based and another non-model-based -- for developing secondary students' understanding of the phenomenon of increase in Earth's average surface temperatures, a core dimension of global climate change (GCC). Building on past research on teaching and…

Growing human populations place increasing demands on our planet, resulting in an array of challenges with both scientific and non-scientific dimensions. These challenges are collectively known as socio-scientific issues (SSIs). It is essential to understand how students learn to use values to reason about SSIs, particularly when dealing with…

Scientific modeling and systems thinking (SMST) is central to the geosciences, yet few studies have documented how and to what extent undergraduate geoscience courses emphasize SMST, as well as factors that might help explain or predict these trends. Here, we present research based on data (n = 2056) from the most recent (2016) administration of…

Water is a crucial topic that spans the K-12 science curriculum, including the elementary grades. Students should engage in the articulation, negotiation, and revision of model-based explanations about hydrologic phenomena. However, past research has shown that students, particularly early learners, often struggle to understand hydrologic…

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…
