Abstract: The macroeconomics course involves a large number of abstract economic concepts, and requires students to systematically master macroeconomic analysis tools, be able to understand and analyze macroeconomic issues from different perspectives. To this end, the article proposes the construction of a“TAD-RIE”six stage blended learning model, which reconstructs course content through the integration of“theory+scenario+policy”and develops micro course resources; based on the Learning Platform, promote case-based online and offline integrated teaching mode and artificial intelligence assisted teaching reform, strengthen the integration of“value shaping - ability cultivation - knowledge exploration”, innovate“two links, three levels, five dimensions”evaluation system. Practice has proven that this model effectively enhances curriculum education and teaching effectiveness.
