A Study on Two-way Distance Learning System of Japanese Language

本研究的目的是开发一个双向多媒体日语学习系统，帮助日语学习者，特别是远程或非课堂的日语学习者，在跨文化交际中更好地进行交流，提高日语学习者的社会语言技能，通过特别关注“会津”（在谈话中的“反向引导”行为）和使用网络上的真实视频片段对他人谈话的“切入”行为。频繁的反向引导行为引导是日语会话行为的特点之一。此外，可能很少有日语学习者仅仅通过观察母语者的行为来注意到合口语的重要性。因此，会津音是学习日语不可或缺的因素，也是提高日语交际能力的关键。作为构建视频数据库的基础数据，本文对视频和音频质量的感知评价进行了小规模的研究。从实验结果来看，考虑到海外日语教学环境中人数较多的Macintosh用户的方便，目前该系统以mpeg 1格式在网上发布视频片段，该系统包含真实的视频片段，并简要介绍了日语教学中的社会语言行为和对话的翻译，所有这些视频片段都可以按需获得。虽然还需要更多的收尾工作，学习者也将能够访问剪辑的修改版本，每当一个人想要学习的对话在较慢的语速和更清晰的发音。获得技能的任务和练习也将在屏幕上准备好。也没有得到用户的评价，对于那些远离日语和日语使用者的真实信息和社会语言信息的学习者来说，该系统将起到很好的帮助作用。

The purpose of the research is to develop a Two-way Multimedia Japanese Language Learning System which helps the Japanese learners who especially are in distance or off-class situations to be better communicators in the cross-cultural situations.The system is to enhance learners' socio-linguistic skills of Japanese, by putting special focus on the "aizuchi" (back-channeling behavior in conversation) and the "cut-in" behavior on others' conversation using authentic video clips on the web.The frequent back-channelings are one of the characteristics of the Japanese conversational behaviors. Besides, there might be very few Japanese learners who notice the importance of the aizuchi just by observing native speakers' behaviors. Thus the aizuchi is a indispensable factor to learn and the key to a better Japanese communication.As for the basic data for the construction of the video database, a small-scale research on the perceptional evaluation on the video and audio quality has been conducted. Judging from its result and considering the convenience for the Macintosh users, rather large populations in the overseas Japanese Language Teaching environment, the video-clips are put in the mpeg 1 form on the web now.This web-based system contains authentic video clips with brief explanation on the featured socio-linguistic behaviors and the transcriptions of the conversations, all of which are available on demand. Although some more finishing works are still needed, the learner will also be able to access the modified version of the clips, whenever one wants to study the conversation in slower speech rate and clearer pronunciation. Tasks and practices for getting the skills will be prepared on the screen as well. Users' evaluation has not been obtained either, the system will be of good help for the learners who are distant from the authentic and socio-linguistic information on Japanese language and its users.
