Practical study is an important way to improve the overall quality of Ideological and political teachers in Colleges and universities. The practical training of Ideological and political teachers in Colleges and universities not only helps to improve the ideological consciousness and teaching level of training teachers，but also promotes the scientific research of training teachers. Through the investigation and research，it is found that the promotion function of practical research to scientific research is less than its promotion to teaching ability. The survey also found that：the significance of practical training in promoting scientific research for scientific research teachers is greater than that for teaching teachers；The significance of practical research for teachers engaged in the research of Marxist theory，the history of the Communist Party of China，ideological and political education and the theory and practice of socialism with Chinese characteristics is more obvious than that of teachers engaged in other research directions. As for the promotion mechanism of College Ideological and political teachers’ practical research base for scientific research，it mainly plays a role through its expansion of Ideological and political teachers’ world outlook and its function of action to promote knowledge.
