Earth Science

High-quality science education is essential for students to become scientifically literate. Model-Evidence Link (MEL) diagrams and build-a-MEL (baMEL) diagrams are instructional scaffolds that create an opportunity for students to build scientific understanding through the evaluation of the connections between evidence and alternative explanations of a scientific phenomenon. The MELs and baMELs allow for a natural incorporation of three-dimensional learning that has been recommended by the Next Generation Science Standards to enhance students’ comprehension. Through this science teaching methodology, students are able to see that by diagramming and then writing about one’s thoughts about the connections between evidence and explanations, one can deepen their understanding of scientific concepts.

The origin of the Universe is something that people have pondered for thousands of years. As evidence has mounted, the Big Bang theory has become the consensus scientific model. Much of this same evidence refutes opposing theories such as the earlier Steady State model. The NGSS for high school includes the nature of and evidence for the Big Bang, providing a rich opportunity to explore—with the help of a scaffold—the connections between evidence and competing models about the origins of the Universe.

This article focuses on investigating the phenomenon of increasing surface air temperatures using a global climate modeling approach.

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 environments. Concurrently, the empirical research associated with climate education has also increased. We used an exhaustive, stepwise process to search for and identify relevant literature, systematically analyzing 178 empirical, peer-reviewed studies focused on climate literacy and education in formal K-16 settings.

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).

Socially relevant and controversial topics, such as the climate crisis, are subject to differences in the explanations that scientists and the public find plausible. Scaffolds can help students be evaluative of the validity of explanations based on evidence when addressing such topics and support knowledge gains. This study compared two scaffolds in which students weighed connections between lines of evidence and explanations for the topics of climate change and extreme weather events.

This high school curriculum offers over 61 data-intensive Earth Science investigations, all set in real-world contexts and includes a variety of other activities, including topical fiction and non-fiction readings and research projects and presentations that build critical life and scientific literacy skills.
