基于“云服务”的多模态课堂口头报告教学行动研究

A Cloud-service-based Pedagogic Action Research on Multimodal Classroom Presentation

基于对“云时代”学习特点以及课堂口头报告多模态化的认识，在系统功能语言学多模态话语分析(SF-MDA)理论的指导下，该文研究尝试设计基于“云服务”的多模态课堂口头报告教学过程，在教学实验的基础上重点探讨如何引导学生充分调动多元符号资源进行课堂口头报告，并通过分组录像对比分析、调查访谈等方法检验教学效果。结果表明：训练前后学生课堂口头报告总体成绩有所提高，其中结构、语速、PPT制作等方面有明显进步；公共“云服务”辅助基于多模态话语分析的教学方式能有效协助学生掌握课堂口头报告的“图式结构”、PPT制作、目光注视、互动等方面的知识和技巧。

This article describes the development of a multimodal pedagogic model characteristic of cloud-service-based assistance in the instruction of classroom oral presentation. Building on Systemic-Functional Multimodal Discourse Analysis(SF-MDA)，the teaching design focuses on guiding students to properly use different semiotic resources to do effective presentation.The purpose of the study is to investigate whether the design of a multimodal instructional format will enhance oral presentation skills.The results reveal that the multimodal nature of the design was favoured by all participants and oral presentation skills improved significantly in “schematic structure”， ppt demonstration， rate of speaking after the instruction. Implications for applying cloud computing technology in multimodal instruction of foreign language teaching are also discussed.
