人体微生态是21世纪生命科学最引人关注的新型研究领域之一。近年来多项研究表明人体微生态与人类健康和多种疾病的发生发展密切相关，相应地在高等医学教育中开展人体微生态学越来越重要。然而，传统的教学模式下，学生始终处于被动学习状态，难以培养学生的学习兴趣，导致教学质量不理想。因此，探索性地将混合教学模式引入到研究生人体微生态教学中对培养新型微生态综合人才具有重大意义。本文拟通过分析人体微生态学教学现状和存在的问题，并综合国内外优质教学理论，探讨将线上和线下相结合的混合教学模式引入人体微生态学教学改革中，以改善教学质量。

Human microbiota is one of the most attractive new research fields for life science in the 21st century. During the recent years, a number of studies have shown that human microbiota is closely related to human health and the occurrence and development of various diseases. Accordingly, it is more and more important to develop courses of human microecology in high medical education. However, in the traditional teaching mode, students are often in a passive learning state, making it difficult to cultivate students’ learning interest, which results in unsatisfactory teaching quality. Therefore, the exploratory introduction of the blended teaching mode into the human microecology teaching for postgraduates is of great significance to the cultivation of new types of microecological comprehensive talents. By analyzing the current situation and existing problems of human microecology teaching, and integrating domestic and foreign high-quality teaching theories, this study explored the introduction of a blended teaching mode of online and offline into the teaching reform of human microecology, so as to improve the teaching quality.
