线上线下汉语课堂教学中视觉模态运用的对比分析

A comparative analysis of the application of visual modality in online and offline Chinese classroom teaching based on multi-modal discourse theory

本文对图像、文字、公式符号及教师动作四个要素在线上线下汉语教学中的运用情况进行数据统计和分析,发现:线上、线下教学都大量利用图像辅助汉语教学,但线上教学的PPT图像类型比线下丰富,线上教学的PPT图像比线下表意更精准;线上教学PPT文字密度大于线下教学,但线上教学的即时书写文字量比线下教学少;线上教学中PPT公式符号的呈现方式更多样;线上教学中教师的头部动作占优势,而线下教学中教师的全身动作占优势。线上教学对于汉语教师的教学整体设计要求更高,视觉模态在线上教学中所承担的作用更重,研究如何充分地利用视觉模态帮助汉语教学还有很大的空间。

This paper makes a statistical analysis of the application of the four elements of online and offline Chinese teaching,i.e.,images,characters,formula symbols and teacher’s actions. The results show that online teaching has more types of andmore accurate PPT images than offline teaching;online teaching has higher text density than offline teaching,but less real-time writing texts than offline teaching;the presentation of PPT is more diverse in online teaching;teacher’s head movementsare dominant in online teaching,while teacher’s whole body movements are dominant in offline teaching. It concludes that theonline teaching requires a higher requirement of Chinese teachers for the overall teaching design,and the visual modality playsa more important role in the online teaching. There is still a lot of room for future studies on how to make full use of visualmodality to enhance Chinese teaching.
