            <abstract>
                <p>While traditional Project-based Learning (PjBL) enhances engagement, creativity, and conceptual understanding, emerging socioformative approaches are pedagogies that highlight the need for interdisciplinary, ethically grounded projects addressing real-world challenges. This study employed a systematic review to investigate the contributions, prevalence, and challenges of PjBL in Science Technology, Engineering, Arts, and Mathematics (STEAM) education while enhancing socio-critical competencies. Thus, 211 articles were downloaded from Google Scholar, Academia, Search 4 Life, Scopus, and Web of Science databases. The PRISMA framework was employed to illustrate the criteria used for the inclusion and exclusion of articles in the review process. Through the rigorous filtering processes, 32 articles fell into the study&#x2019;s scope and were considered and used for analysis. The results from the reviewed studies showed that project-based learning contributes to enhancing students&#x2019; engagement, skills development, and conceptual understanding in STEAM subjects. Most of the reviewed studies employed traditional PjBL, while a few studies&#x2019; methodologies considered trending projects involving transferable skills and socioformation development. An even distribution of PjBL prevalence was found across STEAM subjects, with the highest prevalence in mathematics and science. Also, the reviewed studies marked the highest prevalence of PjBL in higher education and high school education. Studies on PjBL are dispersed across different countries, with the highest prevalence in Indonesia and Spain. Nevertheless, lack of support, challenges such as limited resources, rigid curriculum, teachers&#x2019; inability to select relevant content, and inadequate teacher training on monitoring students&#x2019; projects and providing adequate assessment were also identified. The review provided recommendations, including future directions for research, particularly in relation to education for sustainable social development and AI-supported learning environments.</p>

                <title>Amendments from Version 2</title>
                <p>The current version of the article includes main revisions aimed at improving methodological clarity, conceptual grounding, and the presentation of findings compared to the previously published version. First, the PRISMA framework was explicitly mentioned in the abstract to provide a clearer methodological orientation from the outset of the study. In addition, socioformation, which serves as a key conceptual foundation of the research, was more clearly and explicitly explained in the introduction section. Furthermore, several claims in the introduction were strengthened through the inclusion of appropriate supporting citations to improve academic rigor. The revised version also acknowledges limitations more explicitly by indicating that socio-scientific issues (SSI) and other community- or real-world problem-oriented frameworks were not included in the search criteria and, therefore, were outside the scope of the review. Regarding the presentation of findings, Figure 2 was already provided as a pie chart illustrating the prevalence of Project-Based Learning (PjBL) across STEAM subjects. Finally, the discussion and interpretation of the results, particularly those related to prevalence, were refined and expanded to improve clarity, coherence, and depth of analysis.</p>

            <title>Introduction</title>
            <p>Conventional approaches to Science Technology, Engineering, Arts, and Mathematics (STEAM) instruction are frequently criticized for overemphasizing rote memorization, offering minimal practical application, and failing to link learning to authentic contexts. However, the integration of project-based learning (PjBL) in STEAM subjects has received considerable attention for its potential to engage students and expose them to real-world problem-solving (
                <xref ref-type="bibr" rid="ref19">Han et al., 2016</xref>). Project-based learning has gained popularity in educational research and curriculum changes as a viable teaching strategy for integrated science education, to improve students&#x2019; competencies needed for the 21st Century (
                <xref ref-type="bibr" rid="ref32">Serin, 2019</xref>). Project-based learning pedagogy attracts students&#x2019; attention and curiosity by allowing them to work on projects that apply to everyday situations, in which they face challenges and develop solutions to real-world problems and questions (
                <xref ref-type="bibr" rid="ref3">Almulla, 2020</xref>).</p>
            <p>In addressing contemporary educational challenges, this review adopts a constructivist framework emphasizing learning objectives (
                <xref ref-type="bibr" rid="ref18">Haatainen &amp; Aksela, 2021</xref>) and expands to incorporate more flexible, student-centered approaches that emphasize critical and socio-critical thinking known as the socioformative approach (
                <xref ref-type="bibr" rid="ref13">Flores &amp; Esteva, 2025</xref>). Socioformation is an educational approach that focuses on helping learners develop integral competencies for solving real-life problems in society through collaboration, ethical values, critical thinking, and contextualized learning (
                <xref ref-type="bibr" rid="ref7">del Carmen L&#x00f3;pez-Quesada et al., 2022</xref>). This approach aims to prepare students not only intellectually but also socially, equipping them to engage responsibly with complex societal issues in a rapidly evolving and technology-driven world (
                <xref ref-type="bibr" rid="ref41">Wan, 2025</xref>). In this regard, project-based learning is known for its attributes to develop both technical and non-technical skills. Project-based learning-based education is intrinsically meaningful since it is grounded and involves mature competencies like creativity, critical thinking, collaboration, and communication. Through the PjBL, the teacher&#x2019;s role shifts significantly from being a traditional knowledge transmitter to a guider, facilitator, and mentor while supporting both the cognitive and social development of students (
                <xref ref-type="bibr" rid="ref25">Morcom &amp; MacCallum, 2022</xref>). Thus, project-based learning is sought to equip students with valuable life skills that instill confidence and interest, and equip them with skills and desires to become self-directed lifelong learners (
                <xref ref-type="bibr" rid="ref43">Wurdinger &amp; Rudolph, 2009</xref>).</p>
            <p>While traditional project-based learning promotes constructivist learning and mastery of disciplinary content, the trending PjBL perspectives should emphasize learning objectives over real-world or community-based problems (
                <xref ref-type="bibr" rid="ref24">Luque-Gonz&#x00e1;lez et al., 2025</xref>). Emerging methodologies, such as socioformative projects and STEAM-based projects, offer more contemporary alternatives (
                <xref ref-type="bibr" rid="ref35">Tobon &amp; Lozano-Salmor&#x00e1;n, 2024</xref>). Socioformative projects, for example, focus on action research within communities, fostering interdisciplinary problem-solving and sustainable social development, while STEAM projects integrate creativity and cross-disciplinary collaboration (
                <xref ref-type="bibr" rid="ref16">Guerra-Mac&#x00ed;as &amp; Tob&#x00f3;n, 2025</xref>). The applied methodologies in the reviewed studies of PjBL learning model failed today because it focuses on the &#x201c;product&#x201d; or &#x201c;deliverable,&#x201d; which can be generated by AI. In line with 21st-century requirements. Effective learning projects should emphasize social-emotional and transferable skills development. Socioformative project-based pedagogical practices are key for academic performance through transversal skills (
                <xref ref-type="bibr" rid="ref16">Guerra-Mac&#x00ed;as &amp; Tob&#x00f3;n, 2025</xref>). Thus, employing socioformative pedagogical approaches can contribute to the development of transversal skills and academic performance. Incorporating these approaches highlights potential directions for PjBL to evolve, aligning it with the challenges of the AI era and the development of socially responsible competencies. To implement project-based learning-based instruction, students, in collaboration with teachers, identify the potential problems in their environment. Students collaborate in groups to find solutions within the environment to complex issues grounded in the curriculum (
                <xref ref-type="bibr" rid="ref19">Han et al., 2016</xref>). Students choose what activities to engage in and how to tackle the challenge. Students collect data from many sources, synthesize it, examine it, and draw knowledge from it (
                <xref ref-type="bibr" rid="ref18">Haatainen &amp; Aksela, 2021</xref>). This is a genuine inquiry involving students initiating the process with their questions, embarking on a quest for resources to test ideas and draw conclusions (
                <xref ref-type="bibr" rid="ref22">Larmer &amp; Mergendoller, 2010</xref>). To this end, students discover greater significance in project work when they engage in genuine inquiry, rather than simply retrieving and copying information from books or websites.</p>
            <p>Teachers employ various strategies to enhance student engagement and understanding of different learning subjects. These strategies collectively aim to make learning subjects more engaging, relevant, and effective for diverse students. These include inquiry-based learning, where students actively explore concepts through experiments and problem-solving, fostering critical thinking and curiosity in collaboration with peers (
                <xref ref-type="bibr" rid="ref36">Twahirwa et al., 2021</xref>). Collaborative learning is widely used, encouraging students to work in groups to discuss and solve complex problems, and promoting peer learning, communication skills, and ethics (
                <xref ref-type="bibr" rid="ref19">Han et al., 2016</xref>). Technology integration, such as artificial intelligence (AI), simulations, interactive software, making plans, searching for content, helps visualize abstract concepts to make PjBL more dynamic. In addition, formative assessments, like quizzes and hands-on activities, are frequently utilized to provide immediate feedback, guiding students and teachers in addressing learning gaps (
                <xref ref-type="bibr" rid="ref38">Ukobizaba et al., 2021</xref>). Similarly, formative projects are used to track students&#x2019; learning improvement. Within this regard, modified PjBL approaches such as socioformation, combined with the integration of technologies like AI, are essential for learning different subjects because they foster critical thinking, interdisciplinary understanding, social responsibility, and active student engagement in real-world, technology-driven contexts.</p>
            <p>Studies were conducted and showed the contributions of project-based learning in enhancing students&#x2019; subject performance (e.g., 
                <xref ref-type="bibr" rid="ref20">Holmes &amp; Hwang, 2016</xref>; 
                <xref ref-type="bibr" rid="ref44">Najeeb &amp; Memon, 2022</xref>; 
                <xref ref-type="bibr" rid="ref45">Gomez-del Rio &amp; Rodriguez, 2022</xref>; 
                <xref ref-type="bibr" rid="ref46">Yamin et al., 2020</xref>). However, aspects such as the contributions of PjBL on students&#x2019; engagement, creativity, and communication, and conceptual understanding for socioformation, combined with the integration of technologies like AI, are not sufficiently explored (
                <xref ref-type="bibr" rid="ref16">Guerra-Mac&#x00ed;as &amp; Tob&#x00f3;n, 2025</xref>). Project-based learning has been widely recognized for its contributions to student achievement in mathematics and science (
                <xref ref-type="bibr" rid="ref43">Wurdinger &amp; Rudolph, 2009</xref>). Yet, traditional PjBL approaches often remain disciplinary and content-focused, emphasizing learning objectives over real-world or community-based problems (
                <xref ref-type="bibr" rid="ref24">Luque-Gonz&#x00e1;lez et al., 2025</xref>). These limitations can reduce its effectiveness in addressing interdisciplinary challenges and preparing students for the rapidly evolving, AI-driven educational landscape. Emerging learning approaches, such as socioformative projects and STEAM-based projects, offer more socially and technologically relevant approaches by integrating ethical, collaborative, and problem-solving competencies (
                <xref ref-type="bibr" rid="ref19">Han et al., 2016</xref>). By filling this gap, this review of literature yields the educators&#x2019; awareness and purposeful application of this innovative pedagogy to their regular instruction. This review examines the contributions, prevalence, and challenges of PjBL implementation in STEAM subjects, highlighting opportunities to align PjBL with contemporary pedagogical demands such as student-centered learning, critical and creative thinking, interdisciplinary learning, digital and technological literacy, collaboration, and ethical and socio-critical awareness.</p>

            <title>Methodology</title>
            <p>A systematic review was used to collect data. A systematic keyword combination made using Boolean operators (AND, OR, NOT) was used (
                <xref ref-type="bibr" rid="ref9">Dinet et al., 2004</xref>). Thus, keywords such as &#x201c;project-based learning&#x201d;, &#x201c;project-based learning and students&#x2019; engagement&#x201d;, &#x201c;students&#x2019; skills development&#x201d;, &#x201c;students&#x2019; performance in mathematics and sciences&#x201d;, &#x201c;challenges&#x201d;, socioformative projects,&#x201d; &#x201c;formative projects,&#x201d; &#x201c;STEAM education,&#x201d; &#x201c;AI in PBL,&#x201d; &#x201c;sustainability competencies,&#x201d; &#x201c;socioformation,&#x201c; and &#x201c;sustainable social development,&#x201d; were used to access and download resources. Using search engines such as Google Scholar, Academia, Search 4 Life, Scopus, and Web of Science, 211 resources were downloaded. These databases were deemed valid, relevant, and reliable based on their high reputation for holding high-quality academic studies.</p>
            <p>The downloaded resources were analyzed to decide which materials are to be included and excluded before analysis. At first, duplicates were removed. Hence, 28 duplicated papers were filtered out, and 183 articles remained. In addition, 116 resources were filtered out because they related to project-based learning but for other subjects rather than in STEAM subjects. In addition, reviews of literature articles were also filtered out. Further, articles presented in conference proceedings were removed because they usually have limited peer review, preliminary data, or incomplete reporting, which can affect the reliability and quality of evidence. Thus, 67 remained. Furthermore, to get eligible studies for analysis, a deep screening was conducted to filter out studies focused on PjBL in non-STEAM disciplines. In this regard, studies were excluded if they (i) addressed general pedagogy without a clear PjBL intervention, (ii) lacked empirical data on contributions, prevalence, or implementation challenges, (iii) were purely theoretical or opinion pieces, or (iv) did not provide sufficient methodological detail to judge study quality. Therefore, 32 studies remained and were used for analysis. The downloaded papers were published from 2015 to 2026. This publication range was considered to get findings that are more relevant to the current educational context. Through studies screening, a narrative synthesis approach, and statistical descriptive analysis were used.</p>
            <p>To ensure consistency in study selection, two independent reviewers screened all titles, abstracts, and full-text articles according to the predefined inclusion and exclusion criteria. Inter-rater reliability was assessed using Cohen&#x2019;s kappa, which indicated substantial agreement (&#x03ba;&#x00a0;=&#x00a0;0.78). Any disagreements were resolved through discussion until a consensus was reached. In addition, transparency, completeness, and quality of the study, and the risk of bias assessment were controlled for all employed literature by considering study design, sample selection, clarity of intervention implementation, and outcome measurement.</p>

            <p>The results are drawn from 32 reviewed studies. To analyze data, results were categorized depending on reported multiple learning outcomes, such as engagement, skills, or performance, and challenges to avoid double-counting. In addition, a systematic review synthesizes the prevalence of PjBL based on the distribution of studies in STEAM subjects, education level, and the frequencies of conducted studies per country.</p>

                <title>i) The contributions of PjBL in STEAM subjects</title>
                <p>
The reviewed studies under the contribution were categories in three aspects including engagement, skills, and performance. The engagement category includes studies where the primary outcome was students&#x2019; level of participation, motivation, interest, or involvement in learning activities. The students&#x2019; engagement involves active learning for socioformation. Socioformation as a paradigm of innovation and educational experience aims to identify and solve problems that transform the social-educational-community environment through collaboration, interdisciplinarity, multidisciplinarity, innovation, and systematized projects integrated into education (
                    <xref ref-type="bibr" rid="ref13">Flores &amp; Esteva, 2025</xref>). The skills aspect is indicated by studies where the main outcomes were transferable competencies, not subject scores. The performance category includes studies where the main outcome variable was academic achievement or conceptual mastery.</p>

                </p>
                <p>Students&#x2019; engagement refers to the dynamic participation and involvement in different learning activities (
                    <xref ref-type="bibr" rid="ref22">Larmer &amp; Mergendoller, 2010</xref>). The reviewed studies confirmed that Project-based learning enhances students&#x2019; engagement (e.g., 
                    <xref ref-type="bibr" rid="ref3">Almulla, 2020</xref>; 
                    <xref ref-type="bibr" rid="ref14">Gasana et al., 2023</xref>). For instance, in the study on the effectiveness of PjBL approach to engage students in learning, 
                    <xref ref-type="bibr" rid="ref3">Almulla (2020)</xref> investigated the Effectiveness of the Project-Based Learning (PBL) Approach as a Way to Engage Students in Learning. To carry out a study, questionnaires were employed to collect data on 124 teachers using the project-based learning approach. The results showed that the learning projects enhanced student engagement in sharing information and discussion. In addition, 
                    <xref ref-type="bibr" rid="ref14">Gasana et al. (2023)</xref> employed a quasi-experimental and non-equivalent group design with a quantitative research approach. There were 78 senior students. It was found that students who were taught through project-based learning were motivated to learn linear motion while interacting with robots. Further, 
                    <xref ref-type="bibr" rid="ref27">Pan et al. (2021)</xref> employed a student evaluation of teaching (SET) to assess the project-based learning program. Within this regard, a SET instrument was used to measure the effectiveness of project-based learning. Qualitative data was collected about how students collaborate with their classmates on projects while solving real-world problems. The results showed that students were actively involved in the implementation of projects.</p>
                <p>While the new trend of PjBL intends to develop socioformation, most of the reviewed literature, PBL methodologies employed focused on achieving learning processes (constructivist approach), but did not truly address territorial issues. The applied methodologies treat problems as a mere means for conceptual understanding (constructivism) and do not consider PjBL as a tool for socio-economic bond and environmental sustainability. Only two of the reviewed studies stressed developing social development. For instance, 
                    <xref ref-type="bibr" rid="ref12">Farida and Rasyid (2019)</xref> conducted a study on The Effectiveness of Project-based Learning Approach to the social development of Early Childhood. The study employed a post-test only control design. The two random classes were selected, and each class consisted of 33 students. The control group continued their common learning activity while another group used a project-based learning approach. It was found that the project-based learning approach is effective in stimulating students&#x2019; cognition and social development in early childhood education. In addition, 
                    <xref ref-type="bibr" rid="ref20">Holmes and Hwang (2016)</xref> explored the effects of project-based learning in secondary mathematics education. A mixed-method and longitudinal study was employed to investigate the benefits of project-based learning (PjBL) on secondary-mathematics students&#x2019; academic skill development and cognitive, social, and motivational learning outcomes. The findings suggested that PjBL students were more intrinsically motivated to solve problems in a social learning community. In addition, while assessing the effect of project-based learning on leadership abilities and communication skills, 
                    <xref ref-type="bibr" rid="ref33">Sirotiak and Sharma (2019)</xref> recommended methodologies for construction engineering and management education for undergraduate students who need to learn a combination of technical and non-technical competencies. The study used a pre-experimental pre-test/post-test design. During implementation, students were given responsibilities to lead the team. The results showed a statistically significant difference (p&#x00a0;&lt;&#x00a0;.01) between the pre-and post-test, indicating an improvement in the students&#x2019; ability to set goals, communicate effectively, identify, and organize learning activities.</p>

The findings revealed that the implementation of project-based learning coupled with STEAM-based student worksheet analysis utilizing the ecoprint technique yields a substantial enhancement in learning motivation and student creativity. However, among the reviewed studies, none explicitly employed methodologies with the intention to solve the problem within a territory or leading to the context from the perspective of socioformation.</p>

                <p>Most of the reviewed studies employed methodologies emphasizing students&#x2019; academic performance, ignoring the role of PjBL on environmental sustainability. Only one study was on environmental sustainability. For instance,

The low prevalence was found in Arts, Technology, and Engineering with 16%, 9%, and 6% of prevalence, respectively. Mathematics and science prevail since the concepts often lend themselves to real-world applications, modeling, and hands-on experiments, making it easier for educators to design projects that engage students in inquiry, experimentation, and collaborative problem-solving. In contrast, arts, technology, and engineering subjects may pose greater logistical and safety challenges when implementing hands-on projects, such as the need for specialized laboratory equipment and environmental considerations.

                <title>iii) Challenges linked to the incorporation of PjBL in STEAM education</title>
                <p>The challenges encountered by teachers included difficulties in selecting relevant content, time management, a lack of ability to monitor and provide adequate assessment, and a lack of materials to implement students&#x2019; projects. For instance, 
                    <xref ref-type="bibr" rid="ref39">Viro et al. (2020)</xref> studied teachers&#x2019; perspectives on project-based learning in mathematics and science. The study was to investigate how Finnish pre- and in-service class teachers and mathematics and science teachers (N&#x00a0;=&#x00a0;257) view PjBL. The results showed that PBL is suitable for both revising and learning new content. However, the relative inadequacy of resources and support for PjBL implementation was reported among challenges. In addition, 
                    <xref ref-type="bibr" rid="ref17">Haatainem and Aksela (2021)</xref> carried out a study on Project-based learning in integrated science education: Active teachers&#x2019; perceptions and practices. The study employed a qualitative-led survey and a case study. 244 teachers from early childhood education to upper secondary school from 28 countries participated in the study. Among the results, challenges such as facilitating PjBL, such as time management or laborious planning, technical issues related to the use of different technological tools, and students who got tired because of heavy schedules, were reported.</p>

            <title>Discussion</title>
            <p>While constructivist PjBL prioritizes knowledge construction, socioformative projects focus on community service, ethical engagement, and sustainable problem-solving, providing a pedagogical buffer against uncritical reliance on AI-generated solutions. The reviewed literature showed that PjBL has emerged as a transformative approach with significant contributions to various facets of student development. The purpose of employing different teaching and learning approaches and strategies is to make students successful in different learning subjects (
                <xref ref-type="bibr" rid="ref19">Han et al., 2016</xref>). Most of the reviewed studies were conducted on the contribution of PjBL to students&#x2019; subject performance (e.g., 
                <xref ref-type="bibr" rid="ref36">Twahirwa et al., 2021</xref>), followed by students&#x2019; skills development, such as communication, collaboration, creativity, and critical thinking (
                <xref ref-type="bibr" rid="ref48">Kholid et al., 2022</xref>).</p>
            <p>Project-based learning enhances students&#x2019; engagement by fostering active participation, collaboration, and interest through hands-on, real-world problem-solving activities. The current trend of developing 21
                <sup>st</sup>-century skills requires students to be involved in constructing their knowledge. The application of project-based learning goes hand in hand with the application of active learning pedagogy, whereby students are actively engaged in solving real-world problems through authentic tasks. For instance, 
                <xref ref-type="bibr" rid="ref27">Pan et al. (2021)</xref> found that PjBL contributed to enhancing students&#x2019; active engagement and interest while learning science and mathematics. Thus, through project-based learning, students will find the meaning and application of learning concepts acquired in class to real-life situations, which will, in turn, enhance their interest in learning those subjects.</p>
            <p>The reviewed literature showed that project-based learning supports skills development, equipping students with critical thinking, communication, teamwork, and self-management. PjBL was sought as one of the teaching approaches to enhance 21
                <sup>st</sup>-century skills (
                <xref ref-type="bibr" rid="ref32">Serin, 2019</xref>; 
                <xref ref-type="bibr" rid="ref47">Wurdinger et al., 2020</xref>). Within the same vein, through project-based learning, a competence-based curriculum currently used in different countries was conceived and used to develop students&#x2019; skills such as leadership abilities, improving students&#x2019; mathematical reasoning abilities (
                <xref ref-type="bibr" rid="ref1">Abidin et al., 2020</xref>), and life skills (
                <xref ref-type="bibr" rid="ref43">Wurdinger &amp; Rudolph, 2009</xref>). Teachers should teach and give authentic assessments based on students&#x2019; context to enhance their skills. We concur with 
                <xref ref-type="bibr" rid="ref40">Wakumire et al. (2022)</xref> that if students have effectively acquired subject concepts, the acquired knowledge should be transferred and used in their careers. It is expected that teaching students through project-based learning would increase the number of competent human resources ready to apply skills in their future careers.</p>
            <p>Project-based learning enables students to understand the content. For instance, 
                <xref ref-type="bibr" rid="ref19">Han et al. (2016)</xref> and 
                <xref ref-type="bibr" rid="ref36">Twahirwa et al. (2021)</xref> observed higher performance in mathematics and science through PjBL. Similarly, 
                <xref ref-type="bibr" rid="ref1">Abidin et al. (2020)</xref> found statistically significant improvements in mathematical reasoning and geometry scores when PjBL was incorporated into instructions. These findings highlight the potential of project-based learning to improve academic outcomes, particularly when aligned with the curriculum. However, when students receive authentic learning, as it is the key principle of project-based learning pedagogy, students are likely to understand mathematics and science concepts (
                <xref ref-type="bibr" rid="ref43">Wurdinger &amp; Rudolph, 2009</xref>). Therefore, project-based learning instructions should be employed to enhance students&#x2019; conceptual understanding.</p>
            <p>The reviewed literature showed that PjBL is mostly prevalent in physics and mathematics. These results reflect the role of mathematics and physics across STEAM disciplines, which emphasize problem-solving and analytical skills (
                <xref ref-type="bibr" rid="ref40">Wakumire et al., 2022</xref>). In addition, this pattern may be explained by the nature of science and mathematics, which naturally support inquiry-based learning, experimentation, modeling, and problem-solving activities that align with PjBL principles (
                <xref ref-type="bibr" rid="ref24">Luque-Gonz&#x00e1;lez et al., 2025</xref>). Previous studies have similarly noted that PjBL is particularly suitable for science and mathematics education because it enhances students&#x2019; engagement in authentic investigations and collaborative learning experiences (
                <xref ref-type="bibr" rid="ref1">Abidin et al., 2020</xref>). In contrast, implementing PjBL in arts, technology, and engineering may involve greater logistical, infrastructural, and safety-related challenges, including the need for specialized equipment and learning environments (
                <xref ref-type="bibr" rid="ref50">Vasiliene-Vasiliauskiene et al., 2020</xref>). Therefore, differences in subject characteristics, practical feasibility, and resource availability may explain the uneven prevalence of PjBL across STEAM disciplines.</p>
            <p>The reviewed studies revealed that PjBL is implemented across all educational levels, ranging from early childhood education to higher education. However, the highest prevalence was observed in higher education and high school contexts. This trend may reflect the increasing emphasis on learner-centered pedagogies, critical thinking, and independent inquiry in advanced educational settings (
                <xref ref-type="bibr" rid="ref27">Pan et al., 2021</xref>). Higher education institutions may also possess greater institutional flexibility, technological support, and instructional resources necessary for implementing project-based approaches effectively (
                <xref ref-type="bibr" rid="ref33">Sirotiak &amp; Sharma, 2019</xref>). Nevertheless, the presence of PjBL across elementary and early childhood education demonstrates growing recognition of its value in fostering creativity, collaboration, and problem-solving skills from early stages of learning.</p>
            <p>The geographical distribution of the reviewed studies demonstrates that PjBL has gained international attention across diverse educational contexts. The reviewed literature was more dominant in some countries than in others. This distribution suggests that PjBL is increasingly recognized worldwide as an instructional approach aligned with the development of 21st-century competencies such as communication, collaboration, creativity, and problem-solving (
                <xref ref-type="bibr" rid="ref22">Larmer &amp; Mergendoller, 2010</xref>). In addition, the PjBL in mathematics education may be integrated differently depending on the availability of resources, teacher training, and infrastructure. While some countries like South Africa and Kenya have made strides in adopting PjBL, many other regions face challenges due to limited resources and insufficient training for educators (
                <xref ref-type="bibr" rid="ref2">Aldabbus, 2018</xref>). The relatively small percentages across many countries indicate that the evidence base remains fragmented and unevenly distributed geographically.</p>
            <p>The reviewed literature highlighted challenges linked to the incorporation of PjBL in education. Lack of support, the teachers&#x2019; reluctance, and lack of enough confidence to use PBL, difficulty in time management, and the context where PjBL is implemented, designing reliable assessment tools, played a fundamental role in hindering the effective use of PjBL (
                <xref ref-type="bibr" rid="ref2">Aldabbus, 2018</xref>), indicating an area where more support is needed. It was first suggested that the culture of using PjBL should be spread among schools through workshops, seminars, and training sessions. Second, teachers should be given in-service training on how PjBL is applied. Third, the curriculum should be authentic and purposefully designed to be taught by PjBL. Finally, a special budget for projects should be offered by schools.</p>
            <p>The duration of PjBL implementation across the reviewed literature varies considerably depending on the research design and educational context, ranging from short-term instructional units to multi-year longitudinal interventions. Experimental and quasi-experimental studies, such as those by 
                <xref ref-type="bibr" rid="ref34">Tika and Agustiana (2021)</xref>, 
                <xref ref-type="bibr" rid="ref36">Twahirwa et al. (2021)</xref>, and 
                <xref ref-type="bibr" rid="ref8">Demir and &#x00d6;nal (2021)</xref>, generally implemented PjBL over a limited instructional period, typically a few weeks to one academic term. The authors focused primarily on immediate impacts on academic achievement and attitudes. In contrast, the longitudinal study by 
                <xref ref-type="bibr" rid="ref19">Han et al. (2016)</xref> extended PBL implementation across three consecutive academic years (2008&#x2013;2010), allowing for sustained exposure and stronger effect sizes in mathematics achievement. Also, 
                <xref ref-type="bibr" rid="ref21">Kricsfalusy et al. (2018)</xref> examined PjBL within semester-long integration embedded in a programmatic curriculum rather than a short intervention. More recent AI-enhanced PBL studies, such as 
                <xref ref-type="bibr" rid="ref49">Ruiz Viruel et al. (2025)</xref> and 
                <xref ref-type="bibr" rid="ref41">Wan (2025)</xref>, also appear to follow controlled experimental durations aligned with academic terms. While most studies employed short- to medium-term PjBL implementations. Only a few adopted extended or longitudinal designs, suggesting that sustained, multi-year evaluation of PjBL remains moderately limited in the literature.</p>

            <title>Conclusion</title>
            <p>This review underscores the substantial benefits of PjBL in enhancing learning outcomes in line with socioformation. Socioformative pedagogical practices are influenced by socio-emotional skills; the skills needed to be cautiously developed in the 21st-century era. In this regard, enhancing socio-emotional skills is essential for improved student performance. Socioformative projects can extend PjBL beyond classroom achievement by emphasizing community-based problem solving, ethical responsibility, and sustainable development, thereby fostering socially responsive competencies alongside academic learning. Socioformative projects involve flexible proposals centered on critical and socio-critical thinking to contribute to sustainable social development, featuring interdisciplinarity and a high degree of student agency. It is through social learning projects that students communicate, collaborate, and interact with their peers and teachers in a social setting. Such kinds of projects will enhance transferable skills in students, the skills which AI aided projects fail to develop.</p>
            <p>Based on the reviewed evidence, this study concludes that project-based learning shows promising potential to support students&#x2019; engagement, skill development, and conceptual understanding of STEAM subjects. The findings indicate positive tendencies of universal effects and success. Despite the limited reviewed studies, PjBL appears to be effective if factors such as implementation quality, curriculum alignment, teacher preparedness, and resource availability are observed. However, this review acknowledges persistent challenges that must be addressed to effectively apply PjBL in STEAM education. Given the limited number of studies and the underrepresentation of socioformative applications across STEAM subjects, further rigorous and context-sensitive research is needed to generalize PjBL&#x2019;s overall effectiveness. In addition, future studies should expand into underexplored subjects for diverse educational settings to build a more comprehensive evidence base. One limitation of this review is that related concepts such as socio-scientific issues (SSI) and other community- or real-world problem-oriented frameworks were not explicitly included in the search criteria.</p>

            <p>Dear authors,</p>
            <p> </p>
            <p> Thank you for the revised version of the manuscript. The study addresses a relevant topic in STEAM education, and the use of a PRISMA-guided systematic review is appropriate for the research questions. I also wish to acknowledge that the revisions made since the first review round, particularly to the methodology section, have improved the overall quality of your manuscript.</p>
            <p> </p>
            <p> I have some remaining suggestions. Few of the minor and few important for the coherence, and scholarly contribution of the study. 
                <list list-type="bullet">
                    <list-item>
                        <p>I recommend mentioning PRISMA already in the abstract to improve methodological clarity for readers from the start.</p>
                    </list-item>
                    <list-item>
                        <p>Socioformation is a key conceptual foundation of the study, therefore, it should be defined more clearly and explicitly already in the introduction.</p>
                    </list-item>
                    <list-item>
                        <p>Some claims used to justify the study in the introduction require stronger empirical support. For example, statements regarding the widely recognized impact of PjBL on achievement in mathematics and science, and the limitations of traditional PjBL approaches, should be supported with appropriate citations.</p>
                    </list-item>
                    <list-item>
                        <p>Related concepts, such as socio-scientific issues (SSI) and other community- or real world problem-oriented frameworks, are widely used in the literature. As these do not appear to be included in the search criteria, it is possible that some relevant studies were not captured. I recommend acknowledging this explicitly as a limitation of the review.</p>
                    </list-item>
                    <list-item>
                        <p>Figure 2 currently appears to be an incorrect table, as it refers to the number of pathogens rather than the prevalence of PjBL in STEAM subjects. In addition, there is an inconsistency between the results and discussion sections regarding this data (the subjects in which PjBL is most prevalent). Result state sciences versus physics in discussion. I highly recommend rechecking the data, correcting the figure, and ensuring full alignment between results and discussion.</p>
                    </list-item>
                </list> I hope you find these suggestions helpful, and I look forward to seeing the final version.</p>
            <p>Are the rationale for, and objectives of, the Systematic Review clearly stated?</p>
            <p>Yes</p>
            <p>Is the statistical analysis and its interpretation appropriate?</p>
            <p>Yes</p>
            <p>If this is a Living Systematic Review, is the &#x2018;living&#x2019; method appropriate and is the search schedule clearly defined and justified? (&#x2018;Living Systematic Review&#x2019; or a variation of this term should be included in the title.)</p>
            <p>Not applicable</p>
            <p>Are sufficient details of the methods and analysis provided to allow replication by others?</p>
            <p>Yes</p>
            <p>Are the conclusions drawn adequately supported by the results presented in the review?</p>
            <p>Partly</p>
            <p>Reviewer Expertise:</p>
            <p>STEM/STEAM education, project-based learning</p>
            <p>I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard, however I have significant reservations, as outlined above.</p>

                <p>Dear Reviewer,</p>
                <p> </p>
                <p> Thank you for your input and constructive feedback. The following are responses to the comments provided:</p>
                <p> </p>
                <p> 1) The PRISMA framework was explicitly mentioned in the abstract to provide a clearer methodological orientation from the outset of the study (Kindly see the abstract section).</p>
                <p> </p>
                <p> 2) Socioformation, which serves as a key conceptual foundation of the research, was more clearly and explicitly explained in the introduction section (Kindly see the introduction section).</p>
                <p> </p>
                <p> 3) Several claims in the introduction were strengthened through the inclusion of appropriate supporting citations to improve academic rigor (Kindly see the introduction section).</p>
                <p> </p>
                <p> 4) The socio-scientific issues (SSI) and other community- or real-world problem-oriented frameworks were mentioned as a limitation (Kindly see the conclusion section).</p>
                <p> </p>
                <p> 5) Figure 2 was provided during the submission as a pie chart illustrating the prevalence of Project-Based Learning (PjBL) across STEAM subjects. Finally, the discussion and interpretation of the results, particularly those related to prevalence, were refined and expanded to improve clarity, coherence, and depth of analysis (Kindly see the discussion).</p>
                <p> </p>
                <p> Sincerely,</p>

            <p>"Project-based learning in mathematics and science: a review of contributions, prevalence, and challenges"</p>
            <p> </p>
            <p> 
                <bold>Originality and Relevance:</bold> The article addresses a relevant topic, but its approach is traditional and lacks originality in its current state. By relying exclusively on constructivism and classic PBL, it overlooks emerging pedagogical trends necessary to face the era of Artificial Intelligence (AI), such as socioformation.</p>
            <p> </p>
            <p> 
                <bold>Language:</bold> The English text contains grammatical errors and typos (e.g., "pedagocy", "studeis") that require professional editing.</p>
            <p> </p>
            <p> 
                <bold>Suggestions for Improvement:</bold>
            </p>
            <p> 
                <bold>1. Title:</bold> Update the title to reflect a critical perspective regarding current challenges and specify that this is a systematic review.</p>
            <p> 
                <bold>2. Abstract:</bold> Restructure the abstract to strictly follow the IMRaD format and address the gap regarding AI and sustainable social development.</p>
            <p> 
                <bold>Introduction:</bold>
            </p>
            <p> 
                <bold>3. Moving Beyond Constructivism:</bold> The text grounds PBL exclusively in constructivist theories where students "construct knowledge." It fails to consider other, more current and pertinent approaches. I suggest considering new theories or pedagogical models such as socioformation. Constructivism is insufficient in the AI era, as algorithms can "construct" and organize information faster than humans.</p>
            <p> 
                <bold>4. Other More Current and Relevant Project Methodologies:</bold> Furthermore, you must analyze the shortcomings of traditional project-based learning methodology, which tends to focus more on learning objectives. Consider other methodologies such as socioformative projects and STEAM. Socioformative projects, for example, focus on action research within a territory and sustainable social development through an interdisciplinary approach. This is more relevant for facing the challenges of artificial intelligence. Traditional PBL in science tends to be disciplinary, focused more on content and learning processes than on real community problems.</p>
            <p> 
                <bold>5. Research Gap or Problem Statement:</bold> Expand the problem statement to analyze potential issues, failures, or drawbacks of project-based learning, and consider recent alternative methodologies that are more pertinent to the AI era.</p>
            <p> 
                <bold>6. Research Questions:</bold> Refine the research questions to better address the knowledge gap. Consider integrating the suggestions provided to broaden the scope of analysis.</p>
            <p> 
                <bold>7. Methodology:</bold> Expand the sample size and search criteria. Analyzing only 20 studies is very limited for a systematic review, especially considering the inclusion of sciences. 
                <bold>Suggestion:</bold> Broaden the search by including keywords such as "Socioformative projects," "formative projects," "STEAM education," "AI in PBL," "Sustainability competencies," "socioformation," and "sustainable social development."</p>
            <p> 
                <bold>8. Results:</bold> It is necessary to expand the analysis and focus on a deep critical review. I suggest not limiting the results to simply listing which subjects use PBL. 
                <list list-type="bullet">
                    <list-item>
                        <p>Evaluate whether the PBL methodology employed focuses on achieving learning processes (constructivist approach) or truly addresses environmental or territorial issues (socioformation).</p>
                    </list-item>
                    <list-item>
                        <p>Analyze whether the methodologies treat problems as mere excuses to learn (constructivism) or view the problems as a key purpose of the training itself (socioformation).</p>
                    </list-item>
                    <list-item>
                        <p>Analyze the extent to which the project-based learning focuses on academic performance versus a commitment to transforming environments (socioformative pedagogical model).</p>
                    </list-item>
                    <list-item>
                        <p>Review the extent to which the use of PBL generates activities and products that are automatable in the AI era, and the extent to which non-automatizable processes are addressed, such as an emphasis on critical and socio-critical thinking, ethics, and awareness of sustainable social development.</p>
                    </list-item>
                </list> 
                <bold>Discussion:</bold>
            </p>
            <p> 
                <bold>9. Critical Analysis of PBL Shortcomings Regarding Artificial Intelligence:</bold> The article omits AI. It must discuss how traditional PBL fails today because it focuses on the "product" or "deliverable," which can be generated by AI. Consider proposing more recent methodologies like socioformative projects, where the focus is not on the final product, but on ethical interaction with the community, the ethical life project, and face-to-face collaborative work to solve local needs&#x2014;competencies that AI does not possess.</p>
            <p> 
                <bold>10. Contrast of Pedagogical Models:</bold> Replace the validation of constructivist "learning by doing" with research and problem-solving within a territory or context from the perspective of socioformation. Explain that while constructivism seeks individual learning, socioformation seeks service and environmental improvement, shielding the educational process against uncritical automation. Consider presenting more flexible proposals centered on critical and socio-critical thinking to contribute to sustainable social development, featuring interdisciplinarity and a high degree of student agency.</p>
            <p>Are the rationale for, and objectives of, the Systematic Review clearly stated?</p>
            <p>Partly</p>
            <p>Is the statistical analysis and its interpretation appropriate?</p>
            <p>Not applicable</p>
            <p>If this is a Living Systematic Review, is the &#x2018;living&#x2019; method appropriate and is the search schedule clearly defined and justified? (&#x2018;Living Systematic Review&#x2019; or a variation of this term should be included in the title.)</p>
            <p>No</p>
            <p>Are sufficient details of the methods and analysis provided to allow replication by others?</p>
            <p>Partly</p>
            <p>Are the conclusions drawn adequately supported by the results presented in the review?</p>
            <p>Yes</p>
            <p>Reviewer Expertise:</p>
            <p>My areas of expertise are project-based work in education and the study of educational and pedagogical models</p>
            <p>I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard, however I have significant reservations, as outlined above.</p>

            <body>
                <p>We sincerely thank the reviewer for the constructive and thought-provoking comments. Each suggestion has been carefully considered, and the manuscript has been substantially revised as detailed below.</p>
                <p> </p>
                <p> Regarding &#x201c;originality and relevance&#x201d;, the reviewer noted that the manuscript relied excessively on constructivism and traditional PBL, overlooking emerging pedagogical trends such as socioformation in the AI era. In response, we expanded the theoretical framework to integrate socioformation alongside constructivism. The Introduction (pp. 2&#x2013;4) now explains the limitations of a purely constructivist perspective and introduces socioformation as a model oriented toward ethical life projects, territorial problem-solving, and sustainable social development. Additionally, references to Artificial Intelligence (AI) and its educational implications were incorporated throughout the manuscript, including the Results section under &#x201c;Enhancing students&#x2019; skills for socioformation&#x201d; (p. 9).</p>
                <p> </p>
                <p> Concerning &#x201c;language quality,&#x201d; the entire manuscript was thoroughly revised to correct grammatical errors and typographical mistakes (e.g., &#x201c;pedagocy,&#x201d; &#x201c;studeis&#x201d;). These corrections were implemented consistently across all sections.</p>
                <p> </p>
                <p> With respect to the &#x201c;title:, it was revised to better reflect the critical scope and systematic nature of the study. The updated title "
                    <italic>Project-based learning in STEAM subjects for socioformation: a systematic review of contributions, prevalence, and challenges"&#x00a0;</italic>explicitly emphasizes both socioformation and the systematic review design.</p>
                <p> </p>
                <p> The &#x201c;abstract&#x201d; was restructured strictly according to the IMRaD format. The revised version clearly presents Background, Methods, Results, and Conclusions, and explicitly addresses the research gap concerning AI and sustainable social development (see Abstract section).</p>
                <p> </p>
                <p> In response to the recommendation to move beyond constructivism, the &#x201c;Introduction&#x201d; (pp. 2&#x2013;5) now contrasts constructivist learning theory with socioformation. The fifth paragraph (p. 5) explicitly discusses why traditional PBL models centered on content acquisition are insufficient in the AI era.</p>
                <p> The reviewer&#x2019;s suggestion to analyze other relevant project methodologies was addressed by examining socioformative projects and interdisciplinary STEAM approaches in the Introduction (p. 5). The shortcomings of traditional PjBL, particularly its disciplinary focus and emphasis on deliverables, are now critically analyzed.</p>
                <p> </p>
                <p> The &#x201c;research gap and problem statement&#x201d; was expanded (p. 5) to highlight limitations of traditional PBL and justify the inclusion of socioformative methodologies. Consequently, the research questions were refined (p. 4) to reflect this broader and more critical analytical framework.</p>
                <p> </p>
                <p> Regarding the &#x201c;methodology&#x201d;, the sample size was expanded from 20 to 32 studies through a deeper search strategy using broader keyword combinations related to socioformation, sustainability, and AI (see Methodology section).</p>
                <p> </p>
                <p> The &#x201c;Results section&#x201d; was substantially deepened. Rather than merely listing subject areas, it now critically evaluates whether reviewed studies emphasize constructivist learning processes or socioformative territorial transformation. See &#x201c;Enhancing students&#x2019; engagement for socioformation&#x201d; (p. 8), &#x201c;Enhancing students&#x2019; creativity for socioformation&#x201d; (p. 9), and &#x201c;Academic performance for environment transformation&#x201d; (p. 10). The analysis also distinguishes between automatable outputs and non-automatizable competencies such as ethical reasoning and socio-critical thinking.</p>
                <p> </p>
                <p> In the &#x201c;Discussion&#x201d; (pp. 15&#x2013;17), a critical analysis of traditional PBL in the AI era was added (seventh to ninth paragraphs, pp. 16&#x2013;17). The manuscript now explains how product-oriented PBL may be vulnerable to AI automation, whereas socioformative pedagogies emphasize ethical community engagement and face-to-face collaborative problem-solving. Furthermore, a clear contrast between constructivist and socioformative pedagogical models was incorporated (seventh paragraph, pp. 15&#x2013;16), highlighting the shift from individual knowledge construction to service-oriented, interdisciplinary, and sustainability-focused education.</p>

                    <bold>1. Methodology</bold>
                </p>
                <p> </p>
                <p> Regarding the search criteria, the initial keywords were considered too generic. In response, the search strategy was refined by incorporating more systematic keyword combinations using Boolean operators (AND, OR, NOT). This ensured greater precision and reproducibility in the identification of relevant studies (see Methodology section, first paragraph, p. 4).</p>
                <p> </p>
                <p> Concerning the wide publication time span (2000&#x2013;2023), the review period was narrowed to 2015&#x2013;2026 to better reflect contemporary educational contexts and recent developments in STEAM education. This adjustment strengthens the relevance of the findings (see</p>
                <p> Methodology section, second paragraph, p. 5).</p>
                <p> </p>
                <p> The comment on insufficient explanation of risk of bias was addressed by applying the ROBIS protocol. A clearer explanation of the assessment process and its outcomes was added, indicating an overall low risk of bias (see Methodology section, pp. 5&#x2013;6).</p>
                <p> </p>
                <p> 
                    <bold>2. Data Analysis</bold>
                </p>
                <p> The concern about the small proportion of included studies (20 out of 202) was addressed by conducting a deeper search with expanded keywords and Boolean combinations. This increased the final sample to 32 studies, and exclusion criteria were clarified (see Table 2 in the Figshare repository).</p>
                <p> </p>
                <p> A quantitative meta-analysis was not added due to significant heterogeneity across study designs, contexts, and reported outcomes, which made effect size aggregation methodologically inappropriate.</p>
                <p> </p>
                <p> To resolve overlap in study categorization (engagement, skills, performance), clearer definitions and classification criteria were provided to avoid redundancy (see Methodology section, pp. 5&#x2013;6).</p>
                <p> </p>
                <p> 
                    <bold>3. Results and Discussion</bold>
                </p>
                <p> </p>
                <p> The calculation of prevalence percentages in Figures 2&#x2013;4 was clarified. Percentages were recalculated based on the updated sample of 32 reviewed studies and explicitly explained in the text.</p>
                <p> </p>
                <p> Regarding the alleged contradiction in Holmes and Hwang (2016), a re-examination confirmed no inconsistency with the overall findings; therefore, no additional contradiction analysis was included.</p>
                <p> </p>
                <p> To address overgeneralization, the conclusion was revised to align strictly with evidence derived from the 32 reviewed studies (see Conclusion, p. 17).</p>
                <p> </p>
                <p> 
                    <bold>4. Technical Weaknesses</bold>
                </p>
                <p> </p>
                <p> Citation inconsistencies were corrected by standardizing the use of &#x201c;e.g.&#x201d; throughout the manuscript. Typographical errors, including &#x201c;BjBL was fought,&#x201d; were corrected. The PRISMA diagram was revised to ensure numerical consistency in the inclusion&#x2013;exclusion flow (see Figure 1). Additionally, information on inter-rater reliability (IRR) in the article selection process was added (see Methodology section, p. 5).</p>
                <p> </p>
                <p> 
                    <bold>5. Contextual Gaps</bold>
                </p>
                <p> </p>
                <p> The geographical distribution of studies was analyzed and explicitly reported and analyzed. (see Results, pp. 12&#x2013;13). Education levels (elementary, junior, senior high) were systematically identified and reported (see Results, p. 12). Finally, the duration of PjBL implementation across studies was examined and discussed to enhance contextual depth (see Discussion, pp. 16&#x2013;17).</p>
