Vocational college students should be educated with political and ideological theories, and in the course their morality should be strengthened. An political and ideological educational mode of "instructor plus supervisor" system has been developed, and the three teaching strategies of establishing goals, constructing problems scenarios and experiencing successes have been adopted. The three formal lesson-steps should be learned and made use of, and the process of teaching political and ideological theories should be optimized, so that the effect of political and ideological education can be improved.
