项目摘要

As the increase of the number of foreign students studying in Japan, various problems have increased which must be solved. One of them is concerned with their listening ability of Japanese in lecture rooms. This study was designed to investigate the listening ability of non-native language and propose a guideline for giving lectures so that foreign students can easily understand the lecture.Ten Japanese short sentences recorded from TV or radio programs were presented to subjects under the presence of babble noise, the sound level of which was systematically varied. Seventeen Japanese and thirty-two foreign students were tested individually and asked to write the sentence they heard.The results suggested ; (1) When there are unknown terms or unclear portions in sentences, subjects try to guess them from the context. (2) Knowledge concerning the language contributes to the guess of unclear portions. Unknown terms must be guessed phonemecally, which is a very difficult task. (3) Even though foreign students have high listening ability, they feel difficult to listen to Japanese under deteriorated conditions. (4) When key words are recognized, it is easy to understand sentences.The following guidelines were suggested for giving lectures to foreign students : (1)Use of visual aids such as overhead projectors as well as audio aids. (2)Writing on blackboard, at least keywords. (3)Speaking slowly and clearly. (4)Repeating important points. (5)Use of simple sentence structures and adding useful information to understand the context. (6)Quiet surroundings, especially forbidding private talk during lectures.

随着在日留学生人数的增加，各种问题也随之增多，必须加以解决。其中之一是关于他们在教室里的日语听力能力。本研究旨在调查非母语的听力能力，并提出一个讲课的指导方针，以便外国学生可以很容易地理解讲座。本研究的目的是从电视或广播节目中录制10个日语短句，在存在串音噪声的情况下，系统地改变音量。对17名日本学生和32名外国学生分别进行了测试，并要求他们写下自己所听到的句子，结果表明：（1）当句子中存在未知词或不清楚的部分时，被试会尝试从上下文中猜测。(2)关于语言的知识有助于猜测不清楚的部分。未知词必须通过语音来猜测，这是一项非常困难的任务。(3)虽然外国留学生的听力水平很高，但在恶劣的条件下，他们很难听懂日语。(4)当关键词被识别时，句子就很容易理解了。在给外国学生讲课时，建议遵循以下指导原则：（1）使用投影仪等视觉辅助设备以及音频辅助设备。（2）板书，至少要写关键词。（3）说话缓慢而清晰。（4）重复重要的观点。（5）使用简单的句子结构，并添加有用的信息来理解上下文。（6）安静的环境，特别是禁止在讲座期间私下交谈。
