In order to ensure the quality of ideological and political theory courses in colleges and universities, teachers should externalize Marxist theory into thinking methods and internalize it into their own virtues, and the following work should be done as well: firstly, teaching mode or means should be innovated to realize “two modernizations”, which is reflected in the fact that we should not only really adopt the teaching mode of special topic teaching, but also gradually supplement classroom teaching with micro-lectures and virtual simulation practice courses. Secondly, a performance appraisal system should be established for “internalization and externalization” related work by establishing multiple performance appraisal subjects, drawing up reasonable performance appraisal elements and implementing traceable performance appraisal form. Thirdly, a guarantee mechanism should be established to ensure successful realization of “internalization and externalization”. The first thing we should do is to strictly control the recruitment to ensure the political quality of the teachers of ideological and political theory courses in colleges and universities; the second thing we should do is to appraise and reward the excellent teachers, and to encourage the ideological and political theory teachers in colleges and universities to preach and teach students with the power of example; the third thing we should do is to hold a standard with high pressure and deal with the behavior of ideological and political theory teachers who violate teachers’ morality and virtue cultivation with a zero tolerance attitude.
