Abstract: Methodology-based teaching reform is aimed at improving the comprehensive ability of graduate students in public management disciplines. Guided by scientific methodology，with big data analysis and experimental teaching system as the core to improve teaching，we choose three paths from the establishment of experimental teaching system，the solution of“situation” problems，and the establishment of experimental teaching teams. The School of Government Management of a university in Yunnan Province has continuously explored and improved the postgraduate education model，and has achieved relevant teaching，teaching and research results. Experimental，practical training，and internship training have all achieved significant results. The results show that：a professional，efficient，and interdisciplinary teaching team has been established；“experiment for teaching，experiment for scientific research，and scientific research for teaching” have been set up，with experimental training guidance as the starting point to improve students’ innovative ability and solve practical problems；the methodological teaching system of “normative research-case and empirical research-experimental research-big data research” was constructed.

Key words: public management discipline, methodology, experimental research, teaching reform, graduate students
