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 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. Thematic analysis was then used to identify focal research areas, and describe 1) trends in education research focused on the Earth’s climate and GCC, 2) student knowledge, conceptions, beliefs, and their learning about the Earth’s climate and GCC, and 3) teacher knowledge, conceptions, beliefs, practices, and their preparation about teaching Earth’s climate and GCC. The results of this review summarize challenges faced by both teachers and students in developing their knowledge about GCC. Findings from this literature review will help guide design of curriculum and instruction for climate change content in K-16 classrooms, as well as professional development and teacher preparation about Earth’s climate and GCC in K-16 contexts.

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 learning about Earth’s climate, we use an Evidence-Based Reasoning framework to assess student tasks and interviews from a 3-week, project-developed, model-based curriculum. We observed that the use of a climate model allowed students to reason more effectively about the Earth’s increasing temperatures. They were able to establish the premise and interpret evidence for the phenomenon more effectively with the climate model. Using temperature and carbon dioxide data sets, students observed and quantified the behaviour of climate variables, establishing correlation and causation through data-integrated claims. In doing so, students were able to develop scientific knowledge about climate science as well as understand the processes undertaken by climate scientists in analysing climate data. Given the importance of fostering climate literacy in K-12 students, study findings have implications for both teaching and learning about GCC using climate models, as well as in shifting students’ focus from acquiring knowledge to constructing their own knowledge.

In the past decade, emphasis on promoting “climate literacy” in K-16 science classrooms has increased. Teachers play a critical role in cultivating these opportunities, especially in secondary science classrooms. However, most prior climate education research has focused on students and student learning; little is known about how teachers implement climate-focused curricular interventions. Here, we report findings from a concurrent mixed methods, multiple-case study of four secondary science teachers’ implementation of a new, NGSS-aligned, model-centric climate curriculum module grounded in the use of a data-driven, computer-based climate modeling tool—Easy Global Climate Model (EzGCM). We employ multiple data sources, including video-recorded classroom observations, interviews, and instructional artifacts, and both qualitative and quantitative analyses, to investigate how teachers implemented the curriculum. Findings show that, overall, teachers implemented the curriculum in ways that were less model-centric than designed, placing greater emphasis on EzGCM itself rather than using the model to investigate Earth’s changing climate. Additionally, we present detailed single-case studies of each participant teacher that highlight differences in teachers’ implementation of the curriculum module and their reasoning for making observed instructional decisions. This research sheds light on the design of secondary science learning environments by illustrating the varied ways teachers implement a climate-focused curriculum to support students’ developing climate literacy. This has important implications for the design of climate-focused curriculum and supports for teachers.
