The article first analyzes the difficulties that exist in the ideological and political teaching of this course, such as vague teaching objectives, lack of ideological and political resources, shallow content, and insufficient application of information technology. In response to these difficulties, the course team has carried out teaching reforms, including clarifying the ideological and political teaching objectives of the course, enriching ideological and political resources and expanding teaching cases, deepening ideological and political content and broadening knowledge horizons, applying information technology to innovate teaching methods, and constructing a formative evaluation system. Through these reform measures, ideological and political education in the curriculum has achieved more comprehensive and in-depth development, laying a solid foundation for cultivating intelligent medical talents with a sense of social responsibility and scientific spirit.展开更多
