At the national ideological and political theory teacher forum, Xi Jinping, General Secretary of Communist Party of China Central Committee, lays down specific requirements of "Six Needs" forbuilding of teaching corps and "Eight Unities" for curriculum reform. In terms of "Situation and Policy" course development, it is urgent to build three platforms to support course teaching and effectively improve itsattraction and effectiveness. Based on the ideas toimprove professional qualifications of full-time teachers, to diversify part-time teachers and to regularize expert teams, a complementary teacher platform needs to be built to improve teachers' qualities and abilities. With respect to requirements for integration of flexible andregularteaching systems and combining diversified teachings with integrated evaluations,a platform forthe dual teaching system needs to be built to ensure the flexibility and pertinence of the course teaching. Through the construction of a professional resource sharing platform and a comprehensive teaching resource database, we build a professional and comprehensive teaching resource platform and create conditions to guarantee the course teaching. Construction of the three supporting platforms can solve the major bottleneck problems with teaching, and well-qualified teachers, smooth teaching processes and good external conditions can guarantee better teaching results.
