And the teaching contents of the curriculum can proper carrier of ideological and political education, which provides the necessity and possibility for carrying out the ideological and political construction of the curriculum. There are some “pain points” in the ideological and political construction of the curriculum at present, such as neglecting the teaching goal and guiding value, inadequate mining of ideological and political elements in the teaching content, outdated and single teaching methods, and lack of correct understanding of teaching concepts. Optimization strategies to solve these “pain points” include: Taking content as the carrier, digging ideological and political elements;Education oriented, innovative teaching forms and methods;Guided by the process and improve the evaluation system.展开更多
