Application of the Closed-Captioned Pictures to the English Text Books

我们的项目旨在将视频和激光光盘应用于主要面向大学生的英语教材。在美国期间，我们的一些成员遇到了听觉障碍人士和非英语人士的封闭字幕系统，并知道它可以很容易地进入个人电脑，并用文字处理器进行修改。我们发现它有很大的潜力应用于大学生外语教材。从1994学年开始的三年里，我们开发了这些教科书，在课堂上试用，观察学生的反应，评估效率，相互讨论发现的问题，并对其进行改进。总的来说，封闭字幕教材对我们课堂上的语言训练有很大的动力，主要是因为学生对真实、最新、令人兴奋的内容感兴趣；例如，有广告的美国电视节目。然而，语速快、口语化、俚语、笑话、双关语、特殊口音和方言等都是学生跟上课文内容的障碍。在我们的项目结束时，我们一致认为封闭字幕是非常有效的语言教科书材料，只要我们对封闭字幕文本的能力，训练目的（阅读，写作，听觉交流等），适当的词汇和短语的介绍和注释，以及背景评论都不能太小心。如果文本没有版权问题，可能很快就会有封闭字幕的基本文本出现在互联网上，每个语言教师都可以自由地处理这些文本。

Our project aimed at an application of the videos and laser discs with closed-captions to the English text book mainly for college students. During the stay in the US,some of our members have encountered with the closed caption system for the auditory handicapped people and non English speaking pepole, and knew that it can be easily taken into personal computers and be modified with word processors. We found that it has so great a potentiality to be applied to be used as foreign language text book for college students.For three years from the 1994 academic year, we developed the text books, tried them in our classes, observed the students'reactions, estimated the efficiencies, discussed what we found with cach oter, and improved them.Generally, closed caption text books roused a gerat motivation to the language training in our classes, chiefly because of the students'interest in the contents which is real, up-to-date, and exciting ; American TV programs with commercials, for example. Yet, rapid speech, colloquial expressions, slung, jole, pun, peculiar accents, and dialects, etc. are the hindrances for the students to catch up with what is gong on in the texts.By the end of our project, we agreed that closed captions could be quite efficient materials for the language text book, provided that we cannot be too careful about the aptitude of the closed caption text, purpose of the training(reading, composition, aural communication, etc.), appropriate introductions and notes on the vocabulary and phrases, and background commentary.It may soon be possible to have basic texts from closed captions on internet, which is to be freely procedded by each langeuage teachers, if the tex thas no problem with copyright.
