Nowadays, science, technology, engineering, mathematics (STEM) education has been developed and implemented in many countries. To better understand the research progress in STEM education worldwide, we analyzed 1910 publications collected from the Web of Science Core Collection database. This bibliometric study was performed through software VOSviewer and CiteSpace. Results showed that the research on STEM education will remain thriving in the following years. The USA is the most active country in the research field of STEM education, and the whole world cooperated closely. The majorities of significant institutions in this field belong to the USA. International Journal of STEM Education, Journal of Science Education and Technology and Science Education are the main publications. According to the cluster results of keywords, STEM, STEM education, self-efficacy, technology constitute the knowledge base for STEM education studies. Based the analysis results of keywords and burst detection, STEM achievements, different approaches to discipline integration, educational equality, and teacher education will be the research hotspot in the future. The results give a comprehensive overview on STEM education for scholars quickly understanding the overall progress.
