高校线上线下混合式教学模式的出现是美国O2O商业模式在教育领域的延伸。相较于传统的教学模式，以信息网络技术为支撑的线上线下混合式教学模式在拓展教学时空、整合教学资源、激发学生学习能动性等方面具有显著优势。2016年，我国将加强在线课程开发与利用纳入“十三五”规划，在此政策推动下我国高校纷纷开展混合式教学相关实践，将推动混合式教学视为信息化时代教学改革的重要方向。但我国混合式教学实践工作开展并未取得预期效果，线上教学资源质量保障、线下师生混合式教学素养及混合式教学管理等方面仍存在问题。该文基于线上线下混合式教学理论，针对该模式存在的问题，从教学框架、教学资源、教学主体及教学评价等方面探索创新路径，以推动后疫情时代教学实践的发展。

The emergence of online and offline mixed teaching mode in colleges and universities is an extension of the American O2 O business mode in the education field. Compared with the traditional teaching mode, the online and offline mixed teaching mode supported by information technology has significant advantages in expanding teaching time and space, integrating teaching resources, and stimulating students′ learning initiative. In 2016,China included into the “13 th Five-Year Plan” the development and utilization of online courses. Under this policy, colleges and universities in China have carried out mixed teaching practice and regarded the promotion of mixed teaching as an important direction of teaching reform in the information era. However, the development of mixed teaching practice in China has not achieved the results as expected. There are still problems in the quality guarantee of online teaching resources, teachers′ and students′ offline mixed attainments and the the management of mixed teaching activities. Based on the theories guiding online and offline teaching, focusing on the problems of this mode, this paper explores innovative paths in terms of teaching framework, teaching resources, teaching subjects and teaching evaluation, attempting to promote the development of teaching practice in the post-epidemic era.
