线上线下混合式外语教学的有效实践模式探究

An exploratory study on effective design and practice of blended foreign language courses

线上与线下一体化融合是混合式外语教学面临的主要挑战之一。本研究基于语义波理论指出,线上与线下教学活动应共同推动语义波在低语义重心、高语义密度和高语义重心、低语义密度之间轮转,以确保目标知识在混合式学习过程中的有效积累。通过案例设计,研究从知识点编排、学习资源选择、教学活动设计、过程监控评测等维度探讨了混合式教学模式在大学英语课程中的实际应用,并对未来构建混合式外语教学生态提出了建议。

One of the major challenges in implementing blended foreign language courses is how to realize the organic integration of online and face-to-face instructional activities. Drawing on the semantic waves theory, this study argues that online and face-to-face instructions should be integrated to produce semantic waves, where knowledge is transformed between relatively decontextualized, condensed meanings and context-dependent, simplified meanings, so as to enable cumulative knowledge building. The study illustrates the application of this blended learning model in a college English course with respect to the organization of knowledge objectives, selection of learning resources, design of teaching activities and monitoring of learning processes. Finally, it puts forward suggestions for the construction of the blended foreign language learning ecosystem.
