外语视频直播课堂的模态配置研究

A Study on the Configuration of Modes in Live Video-Streamed Foreign Language Classes

在多模态交际时代,可选择的模态呈现多样性,选择哪些模态以及对所选模态进行怎样的配置才能更加有效地表达意义,成为了多模态交际是否成功的一个关键问题。本文以优质少儿英语视频直播课程为研究语料,首先描述了外语视频直播课堂模态配置的制约因素,接着结合视频多模态标注结果阐释了教师模态配置的总体特征,甄别了各教学环节可优先选择的模态配置方式,总结了不同模态的功能及模态间的协同关系,并以教师讲解知识点环节为例进行了具体分析;最后,本文提出了外语视频直播课堂模态配置应遵循的四条原则,以期给切实改善外语视频直播课堂教学效果提供一定的参考。

The choice and configuration of modes are critical to the success of multimodal communication which involves a wide variety of semiotic resources. This study, taking high-quality live video- streamed English classes for children as an example, first analyzes the constraining factors of the configuration of modes in live video-streamed foreign language classes, then summarizes the fea-tures of modal arrangement by teachers, identifies the ideal ways of arranging semiotic resources in major teaching phases and elaborates on the functions and synergetic relations among various modes. After that, the features and the mechanism of modal configuration in the phase of overt in-struction are elaborated. Finally, four principles governing the configuration of modes are put for-ward, with a view to improving the teaching quality of live video-streamed foreign language classes.
