TED演讲视频中的多媒体课件特征研究

Research on the Features of Multimedia Courseware in TED Speech

多媒体课件的应用日益广泛,但国内对其效果的研究却相对薄弱,导致多媒体课件在课堂教学中成为黑板的替代品,实际教学效果却不佳,甚至有些高校出现学生要求回归传统课堂、拒绝读课件的现象。针对全球演讲领域备受关注的2016 TED大会视频,文章选取了其中不同领域的20个演讲,并通过观察多媒体课件在TED演讲中的媒体表现形式、统计媒体元素在TED演讲中的时间比例,揭示了TED演讲中的多媒体课件特征。最后,文章探讨了TED演讲对我国多媒体课堂教学的启示,以期能为我国多媒体教学资源的可持续开发和创新提供可靠的理论依据,并为高校课堂或视频课程中多媒体课件的设计和开发提供参考。

The application of multimedia courseware is increasingly wide, but its effect research is comparatively weak. This leads multimedia courseware to become the copies of e-books or blackboard in classroom teaching, and its real educational effect is poor. Even some college students require to return to the traditional classroom and refuse to read the courseware. This paper combed and analyzed 20 videos in different fields from the concerned 2016 Technology, Entertainment, Design（TED） conference. The key features of multimedia courseware in TED speech were revealed. The difference between declarative knowledge and procedural knowledge in the aspects of manifestation, displayed proportion of media elements, correlation between specch and courseware was also compared. The methods to improve the development and production of multimedia courseware in our country were also proposed. These results will provide reliable theoretical basis for the sustainable development and innovation of multimedia teaching resources. They will aslo offer reference and model for the design and development of multimedia courseware in college class or video class.
