Research hotspots and development trends of K-12 engineering education research: Bibliometric analysis based on CiteSpace

Abstract

To comprehensively assess the impact of K-12 engineering education research (K-12 EER) and provide insights to stakeholders and policymakers, this study uses the scientometric analysis software CiteSpace to evaluate recent advances in K-12 EER. A search of 885 articles from the Web of Science Core Collection was conducted. This study analyzed publication trends, authors, countries, and research institutions to determine the trajectory of the K-12 EER. In addition, keyword co-occurrence and clustering maps were generated to identify major hotspots, and keyword burst detection was used to demonstrate development trends. The analysis reveals that global interest in the K-12 EER is growing, and the results are accumulating rapidly. However, cooperation between universities, institutions, experts, and scholars must be strengthened. Current significant topics in K-12 EER focus on the practical form of engineering education, its impact on learners, the centrality of engineering design, and teachers' professional development. Research frontiers primarily revolve around the nature of engineering. Future research efforts should promote the systematic integration of K-12 engineering education through the learning process, develop comprehensive measurement tools to assess its impact on learners, and expand research on teachers’ professional development in K-12 engineering education.
