Undergraduates in colleges and universities have great academic potential. In order to cultivate undergraduate innovative scientific research talents, the key is to improve the cultivation mode of undergraduates and stimulate students' academic potential. Taking the evidence-based medicine research group of Guangdong Medical University as an example, this paper systematically analyzes the specific measures and relevant practical experiences of the research team in the cultivation of undergraduates. The research team creatively uses the methods of "student guidance system", "PBL" mode and real-time feedback mechanism, and a complete talent training system has formed to explore a group of excellent undergraduate talents. Through innovative scientific research training, these undergraduates have made many achievements in academic research. This paper hopes these strategies and experiences can provide some reference for the cultivation of undergraduates in colleges and universities all over the country.
