Grand Challenges (GCs) are complex, global, and multifaceted science and societal problems such as climate change, viral pandemics, loss of biodiversity, and quests for new energy sources. In this article, we advance a position, based on current research and theory, that GCs should be a prominent feature of the science curriculum. This move towards a GC-based curriculum challenges the positioning of canonical scientific concepts as the central organising feature of the curriculum, which is typically the default position of most science education programmes. A GC-based curriculum can create natural avenues for students to learn science, develop an interest in science, and build media and information literacy skills to become informed agents of change. Design principles, which help to define what a GC curriculum can look like and guide creation of GC materials, are introduced. These design principles call for the GC curriculum to be contextualised in global issues with local connections, culturally responsive, practice oriented, attentive to student voice, and coherent within and across units. Examples are provided to demonstrate how these design principles are implemented in a sample curriculum. 

Water scarcity poses a significant global challenge, which is often overlooked, particularly in regions with abundant water resources. This article outlines a curriculum designed for middle school students (grades 6–8) that addresses the dynamics of water scarcity and sustainability through five detailed lessons centered around the water cycle. The curriculum is designed to meet the Next Generation Science Standards, specifically focusing on standards ESS2.C and ESS3.C. These standards highlight the importance of water in Earth’s surface processes and the impact of human activities on the environment. The lessons also emphasize scientific modeling and using data as evidence as crucial to understanding water security and action. By emphasizing student voice and incorporating diverse perspectives, the curriculum aims to educate students and empower them to actively address real-world environmental challenges. 

In response to the growing emphasis on addressing global socio-scientific issues like climate change and viral pandemics in K-12 education, we designed three socio-scientific units for middle school science. We call this curriculum Grand Challenges (GC). The GC curriculum shifts from traditional methods to a focus on socio-scientific issues that resonate locally and globally and prepare students for future complexities. GC is a response to the evolving landscape of science education which emphasizes transformative, future-focused approaches that engage students with science content through contextualized, disciplinary practices. This study explores the implementation of the GC curriculum by two teachers, highlighting their choices and the impact on instruction. The findings reveal the crucial role of teachers in actualizing innovative curricula, the challenges of adopting new practices, and the need for robust support systems. This work contributes to understanding how to effectively integrate socio-scientific issues into science education, fostering critical thinking and global citizenship among students. 

Research on socio-scientific issues (SSI) has revealed that it is critical for learners to develop a systematic understanding of the underlying issue. In this paper, we explore how modeling can facilitate students’ systems thinking in the context of SSI. Building on evidence from prior research in promoting systems thinking skills through modeling in scientific contexts, we hypothesize that a similar modeling approach could effectively foster students’ systematic understanding of complex societal issues. In particular, we investigate the affordances of socio-scientific models in promoting students’ systems thinking in the context of COVID-19. We examine learners’ experiences and reflections concerning three unique epistemic features of socio-scientific models, (1) knowledge representation, (2) knowledge justification, and (3) systems thinking. The findings of this study demonstrate that, due to the epistemic differences from traditional scientific modeling approach, engaging learners in developing socio-scientific models presents unique opportunities and challenges for SSI teaching and learning. It provides evidence that, socio-scientific models can serve as not only an effective but also an equitable tool for addressing this issue. 

Justice-centred science pedagogy has been suggested as an effective framework for supporting teachers in bringing in culturally relevant pedagogy to their science classrooms; however, limited instructional tools exist that introduce social dimensions of science in ways teachers feel confident navigating. In this article, we add to the justice-centred science pedagogy framework by offering tools to make sense of science and social factors and introduce socioscientific modelling as an instructional strategy for attending to social dimensions of science in ways that align with justice-centred science pedagogy. Socioscientific modelling offers an inclusive, culturally responsive approach to education in science, technology, engineering, the arts and mathematics through welcoming students’ diverse repertoires of personal and community knowledge and linking disciplinary knowledge with social dimensions. In this way, students can come to view content knowledge as a tool for making sense of inequitable systems and societal injustices. Using data from an exploratory study conducted in summer 2022, we present emerging evidence of how this type of modelling has shown students to demonstrate profound insight into social justice science issues, construct understandings that are personally meaningful and engage in sophisticated reasoning. We conclude with future considerations for the field. 

Abstract COVID-19 creates an opportunity for science classrooms to relate content about viruses to students’ personal experiences with the pandemic. Previous researchers have shown that students are interested in crisis situations like disease outbreaks; however, they primarily acquire information about these events through internet sources which are often biased. We argue that it is important to understand student interest, concerns, and information-seeking behaviors related to COVID-19 to support science classroom learning and engagement about the virus and other potential outbreaks. We surveyed 224 high school students and analyzed their responses to six open-ended questions. We found that students expressed the most interest in topics related to the origin of COVID-19 and vaccines. Their greatest concerns included contracting the virus or someone they know contracting the virus and vaccine distribution. Of our sample, only 6.7% reported using their teachers as their source of COVID-19 information. Science classrooms have the potential to pique students’ situational interest by discussing COVID-19 topics that are important to students, which can increase their academic performance, content knowledge, attention, and engagement in learning about viruses. Moreover, classroom instruction about COVID-19 by teachers has shown to alleviate students’ stress and anxiety. We provide key areas of student interest about COVID-19 to help educators address students’ questions and improve curricular resources on viral pandemics.
