目的 为推动“双一流”建设的稳步推进和满足生物质高素质人才培养的要求，极有必要以本科专业课“多糖化学”为载体，以课程教学为媒介，开展教学改革研究。方法 教学内容与时俱进，在传授基础知识的同时，注重辅以最新的研究成果，激发学习兴趣，引入思政元素。教学方法多样化，利用线上资源、国家级实验平台等进行交互协同化教学，培养学生自主学习能力。结果 通过丰富教学内容和优化教学方法，显著提高了学生的学习能力和创新能力。结论 通过课程教学内容和教学方法改革，提升了人才培养的质量。

The work aims to carry out teaching reform research with the undergraduate major-based course olysaccharide Chemistry" as the carrier and the course teaching as the medium, in order to promote the steady advancement of the "Double First-Class" construction and meet the requirements for the cultivation of high-quality biomass talents. The teaching content was reformed to keep pace with the times. While imparting basic knowledge, it paid attention to supplementing the latest research results, stimulating learning interest and introducing ideological and political elements. Diversified teaching methods were adopted, which used online resources, national experimental platforms, etc. for interactive and collaborative teaching, to cultivate students' autonomous learning ability. By enriching teaching content and optimizing teaching methods, the students' learning ability and innovation ability were significantly improved. Through the reform of teaching content and teaching methods, the quality of talent training has been improved.
