关于外语多媒体教学信息呈现中视听干扰问题的探讨

The Audio and Visual Interference in Instructional Presentation in Multimedia-based Foreign Language Classes

本文从多媒体理论和选择性注意理论出发,从学习者认知角度探讨外语教学信息呈现中的视听干扰问题。作者认为,课堂教学信息的呈现必须顾及学习者的认知加工过程,过量的或者不匹配的视听信息无益于工作记忆中的有效加工,反而造成干扰。因此,教师有必要使用适当的应对策略来消除信息呈现中的视听干扰,降低认知负荷,提高学习效率。

Based upon an account of the Cognitive Load Theory and Theories of Selective attention, this paper discusses the audio and visual interference in multimedia-based foreign language classes. The authors argue that the instructional presentation should comply with the multi-media learning process of the learners and that any inappropriate presentation of audio and visual information causes interference instead of promoting the working memory processing. Therefore it is of great significance to adopt practical teaching strategies to inhibit interference in multimedia presentation in foreign language classes.
