多模态话语分析理论对二语习得研究有着重要影响。基于此,通过分析法国里昂第二大学语言中心的Nicolas Guichon等学者进行的不同多模态形式对二语学习者的学习效果差异研究,探讨了多模态形式在二语学习中需要遵循的三条原则,即信息呈现的多模态性、模态形式的互补性和认知负荷的差异性。 Multimodal discourse analysis theory has an important influence on second language acquisition research. Based on this, through the analysis of different multi-modal forms by scholars such as Nicolas Guichon of Lyon University’s Second Language Center in France, it studies the differences of learning effects on second language learners and discusses the three multi-modal forms to be followed in second language learning Principle, that is, the multi-modalities of information presentation, the complementarity of modal forms and the difference of cognitive load.
