【摘要】：在早期的英语听力研究中,更多研究关注背景知识在听力理解中的积极作用,及生词率对听力理解的影响。但把二者做结合起来的相关研究却不多。本研究主要提出了三个研究问题：(1)生词率对二语学习者的听力理解是否有显著的影响?(2)比较生词率和话题熟悉度哪一个因素对二语学习者的听力理解有更显著的影响?3)主题熟悉度和生词率这两个因素对二语学习者听力理解的交互影响有多大?为了回答上述问题,本研究对杭州在65名国际高中生进行了实证调查.文化宫校区组同学听力测试前进行了生词反复抽查,确保90%正确率,而文三路校区组同学直接进行听力测试。受试者共完成了2篇主题熟悉与不熟悉的听力篇章。听前都完成了关于文章熟悉度的调查问卷。听完篇章后,运用SPSS19.0进行了统计分析。测试结束后,抽取8位学生进行追思法询问。实验结果表明,生词率对二语学习者的听力理解普遍有显著影响。但生词率影响的显著性要弱于背景知识因素,当受试者熟悉篇章话题时,生词率影响减弱,是因为背景知识可以更好地实现自上而下和自下而上相结合的交互式信息处理方式,而单有词汇知识会以自下而上信息处理方式为主,降低听力理解准确度。最后发现背景知识和生词率的相关性不显著,更加确认了两者对听力理解的主效应。
[Abstract]:In the early study of English listening, more studies focused on the positive role of background knowledge in listening comprehension and the influence of the rate of new words on listening comprehension. However, there are few related studies combining the two. The present study raises three questions: (1) whether the rate of new words has a significant effect on the listening comprehension of L2 learners? (2) which factor is more significant to the listening comprehension of L2 learners than the other factors such as the rate of new words and the degree of familiarity with the topic? How do the two factors, the familiarity of topic and the rate of new words, affect the listening comprehension of L2 learners? In order to answer the above questions, this study conducted an empirical survey of 65 international high school students in Hangzhou. In order to ensure 90% correct rate of new words, the students in the group of Wen San Road were tested directly before the listening test. The subjects completed two listening chapters of familiarity and unfamiliarity. A questionnaire on the familiarity of the article was completed before listening. After listening to the chapter, use SPSS19.0 to carry on the statistical analysis. After the test, 8 students were selected for questioning. The results show that the rate of new words has a significant effect on the listening comprehension of L2 learners. But the influence of the rate of new words is weaker than that of the background knowledge. When the subjects are familiar with the topic of text, the influence of the rate of new words is weaker, because the background knowledge can better realize the interactive information processing method of the combination of top-down and bottom-up. Only vocabulary knowledge will be based on bottom-up information processing to reduce the accuracy of listening comprehension. Finally, it was found that there was no significant correlation between background knowledge and word rate, which confirmed their main effects on listening comprehension.
