Introduction: The 21st century is characterized by the profound impact of anthropogenic activities on Earth's interconnected geological, biological, and atmospheric systems, leading to an unprecedented array of environmental crises (Zhou and Gu, 2024). Accelerating climate change, biodiversity collapse, widespread pollution, and resource depletion collectively pose existential threats to both ecological stability and human well-being (Irabor and Onwudinjo, 2025). Addressing these multifaceted challenges requires more than scientific understanding; it demands a deep appreciation for the intricate relationships between human societies and natural systems, reinforcing the critical imperative for environmental literacy (EL). Environmental literacy, as defined by frameworks like the North American Association for Environmental Education extends beyond mere ecological knowledge. It encompasses a holistic understanding of environmental systems, the capacity to critically analyze environmental problems, the ability for independent judgment and action, and a profound commitment to environmental stewardship (Bey et al., 2020). EL is a multi-dimensional construct comprising: Cognitive dimensions: Knowledge and understanding of natural systems, environmental issues, and the interconnections between human and natural systems. Affective dimensions: Attitudes, values, concern, empathy, and motivation towards environmental protection. Psychomotor dimensions: Skills for action, problem-solving, decision-making, effective communication, and active participation in sustainable practices. In an era of rapid information flow and complex environmental narratives, EL is fundamental for informed decision making, responsible citizenship and the cultivation of sustainable Journal of Education, Communication, and Digital Humanities-Vol.2, No.2, Sept. 2025 pg. 37 lifestyles at all levels. Without a populace possessing foundational EL, efforts to mitigate environmental degradation and build resilient societies will be significantly hampered. Within formal education, science education is an indispensable domain for fostering EL. Scientific principles underlying climate change, ecosystem dynamics, and resource management form core components of science curricula, providing a rigorous foundation. Moreover, science education cultivates critical thinking, data analysis, problem-solving, and evidence-based reasoning skills directly transferable and essential for effectively addressing environmental challenges (Mafarja et al., 2025). Science teachers are central to this educational endeavor. They are pivotal agents of change, capable of inspiring, educating, and empowering students to become environmentally literate citizens (Mittal and Bansal, 2024). Their disciplinary expertise allows them to demystify complex environmental scientific concepts, while their pedagogical skills translate abstract knowledge into tangible, real world relevance. Their role extends to fostering scientific inquiry into environmental problems, facilitating ethical discussions, and guiding students towards proactive engagement and sustainable actions. In essence, science teachers act as catalysts, igniting curiosity, fostering critical awareness, and cultivating the skills and attitudes necessary for environmental stewardship. Despite this pivotal role, science teachers often face significant barriers in effectively integrating EL into their instruction. These challenges include curriculum constraints prioritizing traditional content, inadequate professional development in environmental education pedagogies, limited access to resources and outdoor learning opportunities, and the pressure of standardized testing which can marginalize interdisciplinary and experiential learning (Mngomezulu and Ramaila, 2025). Addressing these barriers requires a concerted effort to support teachers with innovative pedagogical approaches and necessary professional backing. 2. Scope and Purpose of the Review Recognizing both the urgency of environmental literacy and the pivotal yet often constrained role of science teachers, this review systematically synthesizes emerging pedagogical innovations aimed at equipping teachers to promote environmental literacy and sustainability education in the 21st century. Specifically, this article seeks to: 1. Identify and describe key pedagogical innovations demonstrating effectiveness in cultivating various dimensions of environmental literacy among students. 2. Analyze how these innovations leverage the unique position of science education to engage students with complex environmental issues. 3. Discuss the enablers and challenges faced by science teachers in implementing these innovative pedagogies. 4. Provide implications for teacher education, curriculum development, and policy to support science teachers as catalysts for environmental literacy. Through a critical analysis of relevant research, this review aims to provide an overview of best practices and emerging trends to inform researchers, educators and policymakers dedicated to advancing environmental literacy for sustainability.

Conceptual Framework: Environmental Literacy and Sustainability Education The concept of environmental literacy has evolved significantly since its inception, broadening to reflect the increasing complexity of environmental challenges. While early conceptualizations often focused on ecological knowledge (McBrideet al., 2013), contemporary definitions, influenced by organizations like theNorth American Association for Environmental Education(NAAEE) (Simmons, 1995), embrace a more comprehensive set of attributes. Today, EL is understood as a multi-dimensional construct encompassing cognitive, affective, and psychomotor domains. 1. Cognitive Dimension: Involves foundational knowledge of natural systems (e.g., ecology, climate science), understanding environmental issues (causes, impacts, solutions), and interconnections between human societies and the environment. It also includes critical analysis skills and problem identification. 2. Affective Dimension: Relates to attitudes, values, beliefs, emotions, concern, empathy, and responsibility towards the environment. Fostering a personal connection to nature and an ethical stance are crucial. 3. Psychomotor Dimension: Encompasses practical skills and behaviors for environmental action, including problem-solving, sustainable decision-making, effective communication, and active participation in civic processes and personal/collective actions. The relationship between scientific literacy and environmental literacy is particularly salient in science education. Scientific literacy, defined as the knowledge and understanding of scientific concepts for informed decision making and civic engagement (Yacoubian, 2018), provides the essential grounding for EL. An environmentally literate individual must first be scientifically literate to critically evaluate claims, understand scientific evidence and appreciate the scientific basis of environmental problems and solutions. Hence, science teachers are uniquely positioned to build this synergistic foundation. Environmental literacy is intrinsically linked to Education for Sustainable Development (ESD). Spearheaded by UNESCO, ESD empowers learners to make informed decisions and take responsible actions for environmental integrity, economic viability, and a just society (Nwosu, 2024). The key connections between EL and ESD include: 1. Holistic Perspective: Both advocate for understanding ecological, social, and economic systems as interconnected. 2. Action Oriented: Both emphasize developing skills, values and attitudes that lead to positive change. 3. Future Oriented: Both aim to ensure future generations' well-being and planetary capacity. By cultivating EL, science teachers significantly contribute to broader ESD goals and equip students with crucial 21stcentury skills such as critical thinking, problem solving, creativity, collaboration, communication, and global awareness (Kioupi and Voulvoulis, 2019). Journal of Education, Communication, and Digital Humanities-Vol.2, No.2, Sept. 2025 pg. 39 4. Theoretical Frameworks Underpinning Effective EL Pedagogy Effective pedagogical approaches for fostering environmental literacy and sustainability are frequently grounded in educational theories emphasizing active, experiential, and socially constructed learning: 1. Constructivism (Piaget, 1950; Vygotsky, 1997): Posits that learners actively construct knowledge through experience and reflection. In EL, this means students investigate environmental phenomena rather than passively receiving facts, underpinning inquirybased learning. 2. Socio-cultural Theory (Vygotsky, 1997): Highlights the importance of social interaction and cultural context. For EL, this translates to collaborative learning, community engagement, and discussions that build shared understanding of environmental issues within social contexts. 3. Experiential Learning (Dewey, 1938; Kolb, 1984): Emphasizes learning by doing and reflecting on direct experiences. This is powerful for EL through direct interaction with nature (e.g., field trips, citizen science) and hands-on problem-solving, deepening understanding and fostering personal connection. 4. Place-Based Education (Sobel, 2004): Explicitly connects learning to the local environment, culture, and community. Drawing on constructivist and experiential principles, it grounds abstract concepts in tangible reality, making learning relevant and fostering stewardship for one's place. These frameworks collectively highlight the need for EL pedagogies that move beyond traditional didactic instruction, advocating for active, engaging and contextually rich learning experiences that empower students to critically analyze, connect emotionally, and act responsibly towards the environment. 5. Methodological Approach 5.1 Search Strategy and Inclusion Criteria A systematic search strategy was employed across reputable academic databases: Web of Science (Core Collection), Scopus, ERIC, PsycINFO and Google Scholar (for broader coverage). Boolean operators combined keywords such as ("environmental literacy" OR "sustainability education" OR "climate change education") AND ("science teacher" OR "science pedagogy") AND ("innovative pedagogy" OR "inquiry-based learning" OR "placebased learning" OR "technology enhanced learning" OR "interdisciplinary teaching"). The primary timeframe for article inclusion was 2000 to 2025, chosen to reflect 21stcentury pedagogical evolution and sustainability awareness. Seminal works predating 2000 were considered for foundational theories. Inclusion criteria focused on: 1) Peer-reviewed journal articles in English; 2) Studies explicitly addressing pedagogical innovations by science teachers (K-12 and tertiary) to foster EL or sustainability education; 3) Empirical studies, reviews, theoretical frameworks providing insights into effective practices; 4) Articles demonstrating clear links between interventions and EL outcomes (knowledge, attitudes, skills, behaviors) or teacher professional development. Journal of Education, Communication, and Digital Humanities-Vol.2, No.2, Sept. 2025 pg. 40 Exclusion criteria included non-peer-reviewed publications, studies focused solely on environmental science content without pedagogical implications, or those lacking sufficient methodological detail. 5.2 Data Extraction and Synthesis Initial search results underwent title and abstract screening. Full-text articles were then meticulously reviewed. For each included article, systematic data extraction coded: bibliographic details, study type, context, specific pedagogical innovations, teacher's role, reported student outcomes (cognitive, affective, psychomotor EL dimensions), methodology (for empirical studies), identified challenges/enablers, and key takeaways. The extracted data was synthesized using a thematic analysis approach (Braun & Clarke, 2006), involving familiarization, initial coding, grouping codes into overarching themes, reviewing, defining and naming themes, and finally weaving them into a coherent narrative. This rigorous methodology ensured systematic identification of robust patterns and insights into effective EL pedagogies. 6.

Lack of Institutional Support: Insufficient support from school administration, lack of recognition for environmental education efforts, or resistance from colleagues. Journal of Education, Communication, and Digital Humanities-Vol.2, No.2, Sept. 2025 pg. 43 - PD focused on curriculum adaptation and development aligned with EL goals. Gaps in Pre-service Teacher Preparation: Inadequate initial training in specific EL content, pedagogical skills (e.g., inquirybased, place-based, values-based), or effective use of environmental technologies. Outcomes of Effective PD: Enhanced content knowledge, increased pedagogical confidence, higher self-efficacy in teaching environmental topics, and a shift towards being a facilitator of environmental learning. Ultimately, science teachers are at the forefront of this crucial educational endeavor. Empowering them with robust professional development, supportive policy frameworks, accessible resources, and strong institutional backing is not merely beneficial but essential for leveraging their catalytic potential in cultivating a generation of environmentally literate citizens. 8. Discussion: This review unequivocally reaffirms the critical role of science teachers as catalysts for environmental literacy (EL) in the 21st century. The synthesis of literature reveals a compelling case for adopting several innovative pedagogical approaches that collectively strengthen the cognitive, affective and psychomotor dimensions of EL among students. The most impactful pedagogical innovations identified, as summarized in Table 1, include Inquiry-Based and Problem-Based Learning, Place-Based and Community-Engaged Learning, Technology-Enhanced Learning, Interdisciplinary and Trans-disciplinary Approaches, Affective and Values-Based Education, and Climate Change Education Specific Innovations. Common threads across these effective practices include a significant shift towards studentcentered learning, a strong emphasis on real world relevance, the promotion of active and experiential engagement and the cultivation of essential 21stcentury skills such as critical thinking, collaboration and communication. These pedagogies transcend the traditional transmission of facts, empowering students as active learners and informed decision makers regarding complex environmental issues. Crucially, the success of these innovations is inextricably linked to the science teacher. Their role has evolved from a purveyor of scientific facts to a facilitator, mentor and guide who enable students to investigate, question, reflect and act. As highlighted in Table 2, the ability of science teachers to adopt and adapt these innovative approaches is paramount, making their ongoing professional development and the supportive ecosystems around them absolutely central to the agenda of fostering environmental literacy. While significant progress has been made, persistent barriers necessitate continued strategic interventions at policy, institutional and individual teacher levels. 9. Implications for Theory and Practice: The findings of this review carry significant implications across various levels of the educational ecosystem, aiming to bolster the role of science teachers as EL catalysts.
