Abstract: Practice of public administration specialty is an important way to realize public administration education and cultivate public administration talents. In reality, the practice of public administration major in colleges and universities is not well organized and implemented, which leads to the long-term disconnection between theoretical teaching and practical training. Educational action research, as the intermediary between educational theory and teaching practice, has its specific theoretical research core and practical operation requirements and is an important theoretical support to guide practice. In accordance with the theoretical requirements of educational action research, the teaching reform of practice of public administration specialty is deeply promoted, which provides a path strategy for colleges and universities to improve the effect of practice in public administration.
