Identifying Gaps and Contributions of Project-Based Learning in Vocational Education and STEM Fields: A Comprehensive Bibliometric Analysis

This bibliometric analysis elucidates the evolution and impacts of Project-Based Learning (PBL) within vocational education, emphasizing its relevance in translating career goals and addressing educational gaps, particularly from 1993 to 2023. Analyzing 555 Scopus-indexed documents, this study utilized advanced bibliometric tools to uncover PBL's growing appeal and its innovative pedagogical integration into design thinking, challenge-based education, and multidisciplinary approaches. Our findings highlight PBL's significant outcomes, including its role in bolstering STEM curricula and fostering critical skill development, thus bridging the gap between theoretical knowledge and practical application essential for the workforce. Despite the documented benefits, our analysis also identifies substantial gaps in research, particularly the scarcity of longitudinal studies on PBL's long-term effectiveness and its comparative efficacy against traditional pedagogies within diverse educational contexts. The study underscores PBL's utility in vocational education as a transformative approach, aligning with dynamic career expectations and the requirements of the knowledge economy. By offering a detailed thematic evolution and pinpointing influential contributions, this research serves as a strategic guide for educators and policymakers, advocating for informed, future-ready educational strategies that embrace experiential learning to meet the evolving needs of students and the labor market.
