With the increasing global emphasis on science, technology, engineering, and mathematics (STEM) education, it is crucial to systematically assess research trends and thematic developments in this field. This paper utilizes bibliometric analysis to examine the scholarly landscape of K-12 STEM education, analyzing 2,645 articles from the Web of Science Core Collection between 2019 and 2023. By analyzing citation metrics, author productivity, institutional and country contributions, and exploring word co-occurrence networks, the study identifies predominant themes and patterns in the field. The findings reveal that advanced countries dominate STEM education research, reflecting significant scholarly interest and investment. The analysis also highlights the role of technological advancements and educational reforms in shaping research trajectories. Additionally, a robust pattern of international collaboration is uncovered, where strategic partnerships across diverse institutions utilize multidisciplinary approaches to effectively address educational challenges. The study suggests the need to broaden research databases to include non-English sources and extend analysis over longer periods for a better understanding of evolving trends. Furthermore, the study recommends embracing interdisciplinary methods and integrating emerging technologies to enhance teaching practices.
