The historical arc of the field is longer than most people realize. Long before ChatGPT captured headlines, rule-based intelligent tutoring systems such as SCHOLAR and GUIDON were already supporting science and mathematics instruction in the 1970s and 1980s, grounded in cognitive science models of how students learn. The 1990s and 2000s saw cognitive tutors and early adaptive platforms migrate from laboratory experiments into real educational practice, while learning analytics slowly began informing instructional decisions. The 2010s brought data-driven adaptive systems, machine learning techniques, and the massive open online course boom, which collectively expanded AI-supported learning environments across the globe. Since roughly 2020, however, generative AI and large language models have marked a genuine turning point, and the publication record shows it dramatically: between the early 1990s and about 2018, research output in this area remained minimal and sporadic, but from 2020 onward the number of publications surged sharply, confirming that AI in science education has become one of the fastest-growing research domains in the learning sciences.

Beneath that headline growth, however, the review uncovers a strikingly lopsided geography of research effort. Of the 80 studies analyzed, 51 percent were conducted in higher education contexts, while only 24 percent took place in K-12 settings and a mere 8 percent in teacher education. This concentration makes structural sense—universities have the organizational flexibility and research infrastructure to pilot and evaluate AI-based approaches—but it means the foundational stage of education, where scientific literacy and digital competencies first take root, remains largely unstudied. Compulsory schooling, where millions of children first encounter physics, chemistry, and biology, is precisely where we know least about how AI tools behave, how teachers adapt them, and how students of different ages respond to algorithmically mediated learning.

The pattern of curriculum integration mirrors this imbalance. Institutional and program-level integration dominated the reviewed literature at 41 percent, with full integration across institutional, program, or policy levels accounting for 55 percent of studies when categories were aggregated. Course and module-level integration followed at 26 percent, while lesson and classroom-level integration trailed at just 11 percent. The review interprets this as a predominantly top-down pattern of implementation: AI is being embedded within broad curricular structures and administrative frameworks rather than emerging organically from individual teachers experimenting in their own classrooms. Notably, the dominance of institutional-level integration aligns with the concentration of studies in higher education, where program-level curricular decisions are more feasible. In K-12 settings, by contrast, integration appears localized and fragmented—isolated lessons or extracurricular use—suggesting structural barriers that limit systemic adoption in compulsory education. Policy and system-level integration remained rare at 14 percent, indicating that even as AI colonizes institutional curricula, it has barely penetrated the governance structures and assessment practices that shape educational systems as a whole.

What are schools and universities actually doing with AI? The answer, overwhelmingly, is personalization. Personalization and adaptive learning emerged as the dominant pedagogical application, appearing in 59 percent of the reviewed studies. Simulation and modeling came a distant second at 21 percent, reflecting AI’s capacity to visualize scientific processes and support laboratory-oriented learning—generative tools such as ChatGPT have even been examined as virtual laboratory teaching assistants that help students design experiments, interpret data, and strengthen scientific reasoning. Inquiry support, content generation, feedback, tutoring, and teacher planning each accounted for small fractions of the remaining applications. This concentration matters because adaptive learning systems are among the most technologically complex and opaque forms of educational AI, relying on continuous collection and processing of learner data to tune instruction in real time. The very features that make them pedagogically attractive also make them the most demanding from a transparency and accountability standpoint.

That tension comes into sharp focus in the review’s ethical analysis, which yields perhaps its most striking findings. Transparency and explainability topped the list of ethical concerns at 25 percent of studies, followed by student agency at 21 percent and the teacher’s role at 13 percent. Taken together, student agency and teacher role account for 34 percent of all ethical considerations, revealing a substantial human-centered strain in the literature that foregrounds autonomy, professional identity, and the relational dynamics between human and artificial agents. The review argues this is no accident: ethical awareness in the field appears functionally connected to the technologies under study, with the opacity of adaptive algorithms directly driving the elevated concern for explainability. Yet the flip side is sobering. Access and equity drew only 6 percent of ethical attention, bias and fairness just 5 percent, and governance and policy a mere 5 percent.

The single most alarming number in the entire review concerns privacy. Just one study—1 percent of the corpus—addressed privacy and data protection as its principal ethical concern, despite the fact that nearly six in ten studies examined data-intensive personalization systems. The review offers several explanations for this blind spot. Privacy is frequently framed as a technical or legal compliance matter rather than a pedagogical concern, reducing its visibility in educational research. Regional differences in data-governance frameworks, such as the GDPR in Europe and FERPA in the United States, create inconsistent treatment of learner data across contexts. Ethics review processes for studies using commercial AI tools or secondary data may simply overlook privacy implications for learners. And the breakneck pace of generative AI adoption has outrun the scholarship meant to evaluate it, creating a temporal gap between technological innovation and research on data protection. Whatever the cause, the review concludes that the field has not yet adequately engaged with the data governance implications of its single most popular AI application.

To knit these fragmented threads together, Molnár proposes a multidimensional framework that conceptualizes AI integration along three interdependent dimensions: the type of AI technology involved, the level of curriculum integration, and the ethical focus of that integration. The framework complements established models such as TPACK, which describes the knowledge teachers need for technology integration, and SAMR, which characterizes increasing levels of task transformation. Its distinctive contribution is the explicit incorporation of ethics into a single analytical structure at the research-synthesis level. An exploratory statistical test within the corpus found only weak, non-robust support for the proposed interdependencies—the association between integration level and ethical engagement did not survive permutation testing—but the patterns remain suggestive. Studies with limited curriculum integration tended to engage with ethical issues only superficially, while more comprehensive integration more frequently came with explicitly stated ethical concern. The framework’s relationships are therefore advanced as propositions for testing in larger samples rather than established regularities, but they offer a practical planning tool: introducing a generative AI writing tutor into a secondary chemistry module, for example, requires systematic evaluation of technology type, integration depth, and ethical dimensions including transparency, agency, and data governance.

The review is candid about its own limitations, which is itself refreshing in a field prone to hype. The single-author design precluded formal inter-rater reliability, though a blinded intra-rater protocol—full recoding of all 80 studies after a minimum two-week interval—achieved 83 percent agreement with Cohen’s kappa of 0.83, indicating almost perfect agreement by conventional benchmarks. The reliance on Web of Science and Scopus excludes educationally oriented studies indexed elsewhere, the English-language restriction may sideline research traditions in East Asia, Latin America, and Central Europe, and the post-2020 concentration of the corpus limits longitudinal conclusions. Publication bias is also a real risk, since successful AI implementations are more likely to be published than failures, potentially producing an overly optimistic picture of what AI actually achieves in science classrooms.

For educators, the practical message is that top-down mandates do not automatically translate into effective classroom practice. The review calls for bottom-up approaches centered on teacher-initiated classroom pilots, collaborative communities of practice, and co-design methods that adapt AI to diverse contexts, supported by sustained professional learning that positions teachers as informed pedagogical decision-makers rather than passive implementers of prescribed technology. With only 8 percent of studies addressing teacher education, the evidence base for preparing educators remains thin, even as TPACK-based studies of science teachers report significant gaps in design competencies and widespread dissatisfaction with existing professional development. For policymakers, the picture is starker still: institutional practice is outpacing regulation, and the review urges frameworks that balance innovation with the protection of learner rights. The deeper conclusion is that AI in science education cannot be understood as a purely technological question. It is simultaneously a pedagogical, ethical, and societal transformation—and right now, the research community is studying the technology while the ethics, the governance, and the classrooms of compulsory education lag dangerously behind.

The study, led by Demet Koç and Duygu Demirbaş Keskin of the Department of Medical Education at Acıbadem Mehmet Ali Aydınlar University, together with colleagues Melike Şahiner and Levent Altıntaş, set out to map, for the first time at national scale, how Turkish medical schools are confronting the climate-health nexus. The research team distributed an online questionnaire to academic leaders responsible for undergraduate medical education across Türkiye, probing the depth of curricular integration, the perceived effectiveness of existing teaching, faculty preparedness, available educational resources, institutional strategies, and the barriers standing in the way of reform. Fifty-three faculties responded, corresponding to a response rate of 58.9 percent—an unusually broad snapshot of a national medical education system.

The headline numbers are sobering. Just 26 percent of responding faculties reported fully including climate change content in their teaching. Another 32 percent indicated only partial integration, while 42 percent reported no inclusion whatsoever. In other words, in more than four out of ten of Türkiye’s medical faculties, the health consequences of a warming planet—heat-related illness, the spread of vector-borne diseases, respiratory impacts of air pollution, water scarcity, and climate-driven displacement—simply do not appear in the training of future physicians. Where climate content does exist, it is typically embedded within pre-existing mandatory courses rather than delivered through dedicated modules, and it tends to focus on basic concepts and general health impacts rather than applied clinical skills.

The gaps run deeper than mere presence or absence of content. The survey revealed that sophisticated and increasingly essential topics are being left out almost entirely. Climate literacy—the ability to critically interpret climate science and communicate it to patients and communities—was rarely addressed. The mental health dimensions of climate change, including eco-anxiety, trauma following extreme weather events, and the psychological toll of environmental degradation, were similarly neglected. Perhaps most strikingly, climate communication—teaching future doctors how to talk with patients and policymakers about climate-related health risks—was infrequently covered, even though physicians consistently rank among the most trusted voices in public discourse.

Faculty preparedness emerged as a critical weak point. Only 5.7 percent of respondents had received any training on how to teach climate-health content. This means that even in faculties where climate change has formally entered the curriculum, the educators delivering it are, in most cases, self-taught. Medical education researchers have long recognized that curriculum reform without parallel faculty development tends to produce shallow, inconsistent teaching, and the Turkish data conform precisely to that pattern. Without structured training programs, conference workshops, or institutional incentives to build climate-health teaching capacity, early adoption risks being symbolic rather than substantive.

Institutional support was similarly thin. Few faculties reported having dedicated structures—such as curriculum committees tasked with planetary health, designated coordinators, or formal policies—that could drive sustained integration. Student-led initiatives, which have proven to be powerful engines of curriculum change in other countries and in international assessment frameworks such as the Planetary Health Report Card, were likewise rare in Türkiye. The absence of these structural scaffolds suggests that even motivated individual faculty members face an uphill battle: without administrative backing, protected time, and dedicated resources, isolated efforts rarely translate into durable curricular reform.

Perhaps the most telling finding concerns perception. When asked to evaluate the effectiveness of the climate education currently offered at their institutions, 48.4 percent of respondents rated it as ineffective. Yet this pessimism coexists with a striking consensus on the importance of the topic: over 80 percent of respondents rated climate change education as important for medical students, and 83 percent supported the development of a national guidance tool to help faculties integrate climate-health content in a standardized way. That gap—between widespread recognition of importance and pervasive dissatisfaction with delivery—captures the central dilemma of climate education in medical training today. Awareness is not the problem. Structure, resources, and coordination are.

The barriers identified by respondents reflect challenges familiar to curriculum reformers worldwide. Overcrowded curricula leave little room for new content in programs already packed with biomedical science, clinical rotations, and licensing requirements. The absence of national learning objectives or standardized guidance means each faculty must invent its own approach, producing fragmentation and duplication of effort. Limited teaching materials in the local language, scarce expertise, and low institutional prioritization compound the problem. The authors of the study conclude that climate change education in Türkiye’s undergraduate medical programs remains fragmented, underdeveloped, and inconsistently implemented, and that structural and pedagogical barriers are actively hindering progress despite growing awareness.

Why does this matter beyond Türkiye? The World Health Organization has described climate change as the single biggest health threat facing humanity, and the Intergovernmental Panel on Climate Change has documented escalating impacts on food and water security, infectious disease patterns, and extreme heat mortality. Health systems themselves are both vulnerable to these impacts and significant contributors to greenhouse gas emissions, placing physicians at the center of both adaptation and mitigation. International bodies, including the Association for Medical Education in Europe, have urged medical schools to embed planetary health across the training pipeline. A physician who cannot recognize heat stroke in a changing climate, counsel patients during air quality emergencies, or anticipate shifting disease vectors is, by any modern standard, incompletely trained. The Turkish findings therefore serve as a warning for many countries where climate-health education has been championed in declarations and position papers but has yet to reach the lecture hall.

The study’s authors point toward a clear path forward. A coordinated national strategy—anchored by the guidance tool that 83 percent of surveyed educators support—could establish minimum competencies in climate and health, provide ready-made curricular materials, and give faculties a shared framework for implementation. Parallel faculty development initiatives would address the training deficit revealed by the 5.7 percent figure, while institutional investment in dedicated structures and student engagement could sustain momentum over time. The researchers emphasize that undergraduate medical education plays a foundational role in shaping future physicians, and that integrating climate-health content has become an urgent priority. If the medical profession is expected not only to understand the health effects of climate change but also to lead mitigation, adaptation, and advocacy efforts, that preparation must begin in medical school. Türkiye’s national survey has measured the distance between aspiration and reality—and, in doing so, has handed educators, policymakers, and professional bodies a detailed map of exactly what must change.

The study, led by Bahati Shabani Nzeyimana and M. Sheela Mary of Bishop Heber College in Tiruchirappalli, with collaborators from Hyderabad and Brazil, set out to move beyond anecdotal claims that universities are ‘mainstreaming’ sustainability. Instead, the researchers built a framework of five key concepts, each mapped to clusters of the Sustainable Development Goals. Key Concept 1 covers environmental education. Key Concept 2 addresses health and well-being. Key Concept 3 captures an inclusive and equitable society. Key Concept 4 encompasses peace, justice and governance. Key Concept 5 deals with climate action and disaster management. By applying this lens to curricula across different categories of Indian higher education institutions, the team could quantify not just whether sustainability appears in teaching, but which dimensions of it thrive and which languish.

The methodological design is a hybrid. On the quantitative side, the bibliometric analysis mined Scopus-indexed publications from 2014 through 2025, tracing how research output related to the Sustainable Development Goals has evolved in India since the goals were adopted. This publication-level evidence provides a proxy for institutional attention and expertise. On the qualitative side, the five key concepts framework was used to systematically evaluate curricula across central universities, state universities, technical institutions and private universities. The mixed methods approach matters because documents alone can mislead: a university may publish extensively on climate science without ever requiring students outside that discipline to encounter it. Pairing publication trends with curriculum assessment gives a fuller picture of what students actually experience.

The headline finding is striking. Environmental education, Key Concept 1, is mandated by between 65 and 90 percent of the institutions examined, making it by far the most deeply embedded dimension of sustainability in Indian higher education. The researchers attribute this dominance largely to regulatory requirements, since statutory bodies overseeing Indian universities have progressively pushed environmental studies into compulsory coursework. In practical terms, millions of Indian undergraduates now encounter at least a core module on ecosystems, pollution, resource conservation or environmental law, regardless of their chosen degree. This is a genuine achievement, and one that distinguishes India from many countries where environmental literacy remains an elective afterthought.

But the picture darkens as the analysis moves beyond the environmental pillar. Key Concepts 3 and 4, covering inclusive and equitable society and peace, justice and governance, are present in curricula but only selectively integrated. Courses on social inclusion, gender equity, institutional transparency or access to justice tend to appear in specific programmes, such as social work, law or public administration, rather than as transversal requirements for all students. Key Concept 2, health and well-being, and Key Concept 5, climate action and disaster management, show similarly fragmented patterns. The study characterises the overall adoption as fragmented yet complementary: different categories of institutions contribute different pieces of the sustainability puzzle, but no single university type delivers the full spectrum, and students’ exposure depends heavily on where and what they study.

This fragmentation has consequences that extend well beyond academic taxonomy. The Sustainable Development Goals were designed as an indivisible agenda, in which progress on health reinforces progress on education, which in turn underpins climate resilience and equitable institutions. When a curriculum concentrates overwhelmingly on environmental content while treating health, inclusion and governance as optional specialisms, graduates may emerge with a deep but narrow understanding of sustainability. An engineer may master pollution control without ever studying disaster preparedness; a business student may learn corporate environmental reporting without encountering social equity frameworks. The Indian case suggests that regulatory mandates, while powerful, tend to pull a single dimension of sustainability into the mainstream rather than the whole agenda.

The bibliometric component adds temporal depth to this diagnosis. The 2014 to 2025 window captures the entire lifespan of the 2030 Agenda, allowing the researchers to observe how scholarly engagement with the goals has grown in India over more than a decade. The publication data reveal expanding research attention to sustainability themes across the higher education sector, yet the curriculum findings show that this research momentum has not translated uniformly into teaching. Publications cluster in disciplines already oriented toward environmental science, reinforcing the same imbalance seen in course requirements. In other words, the environmental dominance visible in curricula mirrors the disciplinary distribution of the research base itself, creating a feedback loop in which environmental topics attract more scholarship, which in turn justifies more environmental coursework.

To address these gaps, the study proposes a Sustainability Excellence Model built on the complementary strengths and weaknesses identified across institution types. The model emphasises collaborative pathways: central universities, state universities, technical institutes and private universities each hold distinctive capabilities, and the framework argues that systematic, transversal integration of the goals will require these institutions to share curricula, expertise and best practices rather than working in isolation. Transversal integration is the operative phrase. Rather than confining sustainability to a single compulsory environmental studies paper or to specialist degrees, the model envisions sustainability concepts threaded through engineering, commerce, humanities and health programmes alike, so that every graduate, whatever the discipline, encounters the full range of dimensions from environmental stewardship to social justice and climate resilience.

The findings arrive at a consequential moment for Indian higher education. With national policy reforms reshaping degree structures and an expanding emphasis on multidisciplinary learning, universities are actively revising curricula, creating a rare window of opportunity to embed the goals more comprehensively. The study’s framework offers policymakers and university leaders a practical diagnostic tool: by scoring curricula against the five key concepts, institutions can identify precisely which dimensions of sustainability their students never encounter. For a country that will graduate some of the largest cohorts of professionals in the world over the coming decades, the difference between a graduate who has studied only environmental science and one who has engaged with health equity, inclusive institutions and disaster governance could shape how effectively India delivers on its 2030 commitments.

What makes this research resonate beyond India is its methodological portability. The five key concepts framework distils seventeen sprawling goals into five teachable domains, offering education systems elsewhere a template for auditing their own curricula with comparable rigour. The study’s core insight, that regulatory mandates drive deep but narrow integration, is a warning for any jurisdiction relying on a single compulsory course to deliver sustainability education. Depth in one pillar is not breadth across the agenda. As the 2030 deadline approaches, the Indian experience documented in this study suggests that the next frontier of sustainability in higher education is not persuading universities to care, most already do, but persuading them to care about all of it, everywhere in the curriculum, for every student.

The problem the researchers set out to address is well documented. Globally, digital technologies have become a core element of primary teacher training, with organizations such as ISTE and UNESCO pushing for classroom technology competence, and with curricula like Australia’s demanding that students develop algorithmic thinking and problem-solving skills embedded in authentic contexts. Yet studies of initial teacher education consistently reveal that programs emphasize technological knowledge while neglecting technological pedagogical knowledge, the crucial understanding of how to teach with and about technology. Without that, pre-service teachers tend to fall back on generic strategies, reproducing commercial step-by-step coding activities without conceptual understanding, or relying on loosely connected, activity-based lessons that look engaging but lack instructional coherence.

The research team, led by Peter Curtis, Michael D. Carey and Natalie McMaster of the University of the Sunshine Coast, together with David A. Martin of Edith Cowan University, points to striking evidence of this gap. In a frequently cited study by Bower and Falkner, when pre-service teachers were asked to list pedagogical strategies for developing students’ computational thinking, most simply equated computational thinking with using technology, and only one explicitly mentioned coding. Even more telling, the candidates reported high confidence in their abilities, a phenomenon the researchers describe as a third order of ignorance: being unaware of one’s own lack of pedagogical knowledge. Systematic reviews of computational thinking in teacher education reach similar conclusions, finding that translating confidence with digital tools into meaningful classroom practice remains a persistent challenge.

The 3C Model, whose three Cs stand for Context, Capabilities and Computational focus, emerged from an earlier qualitative study by Martin, Curtis and Redmond that examined how primary school students learned coding and computational thinking through the framework. That study used a triangulated design combining semi-structured focus-group interviews, analyzed through Clarke and Braun’s thematic analysis with NVivo software, and an insider researcher’s systematic observations and reflective field notes analyzed through Schön’s framework of reflection-in-action and reflection-on-action. The findings showed that the model enhanced student engagement and supported curriculum learning outcomes, and subsequent work by Wang and Kale highlighted its potential as a developmentally appropriate approach for building foundational computational thinking skills in pre-service teachers.

What distinguishes the 3C Model is its explicit grounding in established learning theory. The framework is anchored in Piaget’s theory of cognitive development, specifically targeting children aged around 10 and 11 who sit near the transition from concrete operational to formal operational thinking. At this stage, learners can reason logically about tangible experiences but still rely heavily on concrete, contextualized material to support cognitive processing. The model also builds on the Concrete-Representational-Abstract instructional sequence and the Language Model, both drawn from mathematics pedagogy and rooted in Bruner’s theory of enactive, iconic and symbolic representation. The researchers are candid that TPACK, the influential framework describing the intersection of technological, pedagogical and content knowledge, tells teachers what they need to know but does not prescribe how to sequence instruction. The 3C Model fills that translational gap.

In practice, the model unfolds across a five-lesson sequence. Lesson 1, Context, introduces curriculum content through an authentic, culturally appropriate problem scenario that integrates digital technologies with other learning areas such as science, health or mathematics. Lesson 2, Capabilities, has students explore what a digital tool such as Scratch or a micro:bit can actually do, without writing any code, while the teacher elicits pre-coding language like if-then and repeat until through structured discussion. Lessons 3 and 4, the Computational focus, support a deliberate and gradual shift from student-familiar everyday language to the formal abstraction of coding and algorithmic thinking, with students acting out algorithms physically before translating their pseudocode into block-based programs. Lesson 5 invites students to create a unique artifact through project-based learning, applying their new skills to a problem of personal or community relevance.

Two design choices make the framework particularly notable for equity. First, because individual devices are not central to developing computational thinking in the early lessons, students can engage meaningfully with complex coding concepts in a largely unplugged environment, allowing schools with limited computing resources to participate fully. Second, the delayed introduction of abstract code gives teachers natural opportunities to differentiate instruction, supporting learners who need concrete representations, language support or extra scaffolding. The authors provide worked examples spanning year levels, including an upper primary unit integrating health, English, mathematics and digital technologies using Scratch, and a lower primary beach safety sequence that weaves together the Blue-Bot block-coding app, mathematics and English, alongside a marking rubric and assignment templates hosted in an open science repository for other teacher educators to adopt.

The team also reports preliminary evidence from an exploratory implementation, in which the 3C Model was embedded into coursework as pedagogical learning and assessment tasks at two Australian universities. While the authors are careful to characterize this as an informal investigation rather than a formal research study, pre-service teacher feedback suggested increased confidence and improved instructional skills in teaching coding and computational thinking. The researchers stress, however, that prerequisites matter. Programs should introduce the model only after candidates have studied TPACK and the Concrete-Representational-Abstract approach or Language Model in their technologies and mathematics coursework, since understanding the gradual release of responsibility and the principles underlying those sequences is critical to teaching coding through the model’s structure.

The implications extend beyond individual classrooms. The authors argue that embedding digital competence as a core professional expectation should be supported by incorporating frameworks like the 3C Model into accreditation and curriculum standards, and they connect the work to the United Nations Sustainable Development Goal 4 on quality education by framing it as a route to equitable access to high-quality teacher preparation. Future research, they say, should investigate the model at scale, including longitudinal exploration of pre-service teacher confidence, pedagogical shifts and student outcomes. If those studies bear out the early promise, a model that asks children to walk an algorithm before they type one may become a standard fixture of how the next generation of teachers learns to teach the language of computers.

The stakes could hardly be higher. Secondary school learners occupy a pivotal developmental window during which values, attitudes, and lifelong habits take root. At this stage of adolescence, students develop the abstract reasoning, ethical judgment, and sense of social responsibility that complex environmental issues demand. International frameworks, including Sustainable Development Goal 4.7 and UNESCO’s Education for Sustainable Development agenda, explicitly call for education systems to move beyond knowledge transmission toward transformative learning. When environmental education is intentionally integrated into secondary curricula, the review argues, it can cultivate the critical thinking, systems thinking, and problem-solving skills that empower young people to engage with environmental challenges at local, national, and global scales. But the authors found that in many African contexts this potential remains largely unrealized, with environmental concepts often treated as peripheral add-ons rather than core learning priorities.

The research team, led by Victor Okoth Saoke of the University of Embu in Kenya alongside colleagues at the University of Embu and the University of Hail in Saudi Arabia, conducted an extensive search across Scopus, Web of Science, Google Scholar, and African Journals Online, supplemented by grey literature from UNESCO, UNEP, the World Bank, and FAO. From an initial pool of 672 records, rigorous screening narrowed the field to 22 studies meeting strict eligibility criteria, including empirical designs, African secondary school settings, and clear focus on curriculum integration, pedagogy, learner outcomes, or institutional factors. Quality was assessed using the Mixed Methods Appraisal Tool for empirical studies and the AACODS checklist for grey literature. The methodological landscape of the included research was diverse: twelve systematic reviews, four qualitative investigations, two mixed-methods studies, two policy analyses, and two quasi-experimental studies, with geographic coverage spanning Ethiopia, Nigeria, Tanzania, South Africa, and beyond.

Three dominant models of curriculum integration emerged from the synthesis. The infusion model, the most common entry point, embeds environmental concepts across existing subjects such as biology, geography, agriculture, and social studies. When executed intentionally, infusion fosters interdisciplinary thinking, allowing a single phenomenon like river ecology to be examined through hydrology, land-use economics, and civic responsibility simultaneously. The review found this approach particularly pragmatic in resource-constrained systems where adding new subjects is politically or financially difficult. However, without careful curriculum mapping and explicit learning outcomes, infusion degrades into a disjointed series of mentions, and teachers facing heavy examination pressure routinely sideline environmental content that is not assessed.

Stand-alone environmental science subjects offer a contrasting model with distinct advantages. By dedicating timetable space to sustained inquiry, fieldwork, and project-based assessment, well-designed stand-alone courses can produce deeper conceptual understanding and more robust competency development. Naming a subject as environmental science also carries symbolic weight, signaling institutional priority and legitimizing investment in specialist teachers and materials. Yet the review cautions that stand-alone subjects are not a panacea. In crowded timetables and under-resourced contexts, they often become electives restricted to better-funded schools, reproducing equity gaps in environmental literacy. The third model, whole-school approaches, treats sustainability as a school-wide enterprise spanning curricula, management routines, student eco-committees, gardens, waste management, and community partnerships. Global programs such as Eco-Schools exemplify this strategy, and evidence shows substantial gains in learner attitudes, leadership, and everyday sustainable practices because environmental responsibility becomes a lived habit rather than a one-off lesson.

Pedagogy emerged as at least as important as curriculum placement. The literature converges on a clear finding: experiential, outdoor, and inquiry-based teaching methods consistently outperform didactic, lecture-based instruction in strengthening environmental knowledge, attitudes, and behaviors. Experiential learning grounded in activities such as water-quality testing, biodiversity surveys, and school waste audits deepens retention and strengthens the affective attachment to nature that predicts conservation behavior, provided hands-on activity is paired with structured reflection. Outdoor and place-based learning enhances cognitive, social, and emotional outcomes simultaneously, fostering connectedness to nature, a psychological construct strongly associated with pro-environmental attitudes. Problem-based learning reframes environmental topics around authentic local dilemmas, from polluted rivers to groundwater scarcity, cultivating the systems thinking and collaboration needed for sustainability-oriented citizenship. Service learning and school-community projects add a civic dimension, giving students real-world experience of environmental action and its consequences.

The impact on learners follows a consistent but uneven pattern. Environmental knowledge gains are robust and well-documented across study designs, with meta-analytic evidence confirming significant short-term improvements in understanding of ecosystems, climate change, and conservation practice. Attitudinal shifts, including greater care for nature and stronger environmental values, are also widely reported, particularly in programs using experiential and participatory pedagogies such as fieldwork, citizen science, and service learning. Behavioral outcomes, however, are the most contested. Some school and community programs report meaningful increases in recycling, energy conservation, and tree planting, while other evaluations find modest or statistically insignificant effects, especially for behaviors requiring sustained effort or structural support. Self-reported measures frequently inflate estimates compared with observed behaviors, and evidence for long-term retention of both knowledge and attitudes remains thin due to short follow-up periods.

The review identifies a cluster of structural barriers that repeatedly undermine implementation. Teacher preparedness stands out as a central constraint: many secondary school teachers lack formal training in environmental education or education for sustainable development, limiting their confidence and capacity to integrate environmental concepts into subject teaching. Curriculum overload compounds the problem, as examination-oriented systems push teachers to prioritize assessed content over cross-cutting themes. Resource constraints further limit experiential approaches, with many schools lacking teaching materials, laboratory facilities, outdoor learning spaces, and community partnerships. Weak assessment frameworks reduce accountability, making it difficult to evaluate whether environmental education actually influences learner behavior. The authors also flag equity concerns, noting that high-quality environmental education experiences are disproportionately available to better-resourced schools, risking a widening of existing educational inequalities unless policy deliberately prioritizes low-cost, high-impact interventions and scalable teacher training.

Despite these challenges, the review’s conclusions are constructive. Environmental education holds substantial promise as a transformative force in secondary schooling, but realizing it demands coherent, system-wide effort. The authors advocate hybrid strategies that combine infusion across all classrooms, targeted stand-alone courses for depth and specialist skills, and whole-school programs that cultivate habits and agency, all supported by sustained teacher professional development, community partnerships, and assessment reform that rewards inquiry, practical skills, and civic action. Programs addressing psychological mediators such as environmental identity, self-efficacy, and social norms show the strongest behavioral benefits. The review also highlights a critical research gap: longitudinal, context-sensitive studies tracking how school-based environmental education shapes learners’ trajectories into adulthood remain scarce, and the authors call for mixed-methods, multi-level designs capable of demonstrating lasting impact. Bridging the persistent gap between policy aspiration and classroom reality, the study concludes, is the decisive task if African secondary schools are to produce a generation equipped not merely to understand the environmental crisis but to act upon it.

The review’s methodological transparency reflects broader shifts in how education evidence is produced and trusted. By following PRISMA reporting standards, the authors made their search strings, eligibility decisions, and appraisal steps auditable, which matters in a field where advocacy often outruns evidence. The inclusion of policy documents alongside empirical studies is also notable, since it allowed the team to compare what governments promise on paper with what classrooms actually deliver, a comparison that proved central to their diagnosis of implementation gaps.

One underappreciated dimension of the findings concerns measurement itself. Because most behavioral outcomes in the included studies relied on learner self-reports, the true effect of school programs on everyday practices such as waste sorting or water conservation remains uncertain. The authors’ call for observational designs and longer follow-up periods echoes a wider concern in environmental psychology, where the link between stated intentions and sustained behavior is known to be fragile. Studies that track learners beyond graduation, into household and community settings, would provide far stronger evidence of whether secondary schooling produces durable environmental citizens.

Geographic coverage also deserves scrutiny. The included studies clustered in a handful of countries, leaving large parts of the continent, particularly Francophone and Lusophone Africa, thinly represented in the evidence base. This unevenness limits the generalizability of the synthesis and means curriculum reforms in many nations are proceeding without locally relevant research. The authors suggest that investment in African education research capacity, including support for local journals and open-access publication, would help close this gap.

Finally, the review’s emphasis on psychological mediators such as connectedness to nature and self-efficacy offers a practical lever for designers. Programs that deliberately build emotional bonds with local environments, rather than transmitting facts alone, appear most likely to convert classroom learning into lifelong stewardship.
