In order to explore the development of research of science teacher(RST), 904 articles from the Web of Science (WoS) core set based on bibliometric methods through R software were analyzed in this research. Specifically, it examined the co-occurrence relations of countries/regions, major journals, most cited references, and hot keywords from the macroscopic, mesoscopic and microscopic level of RST. The results showed that the core strength of RST is mainly from traditional industrialized countries such as the United States, Australia, and Britain. And some top journals in science education (such as Journal of Research in Science Teaching, Science Education) has to pay more attention on RST, it may also appeal to lots of top journals in general teacher education (such as Journal of Teacher Education, Teaching and Teacher Education). The research on science teachers was guided by several educational theories about teacher research, such as the teacher epistemological belief, reflective practice, and PCK. Moreover, theories in science education such as scientific literacy, scientific conceptual change also becomes the theoretical basis for science teachers' teaching practice and scientific inquiry instructing. The knowledge, key competences, dispositions, and professional development of science teacher are the main keywords and hot topics in the field of RST.
