词汇广度和深度对二语水平的预测力评估

摘要

在过去二十年间，不管是在第一语言习得还是第二语言习得研究领域，词汇的地位已上升成为语言能力的一个组成部分。为了探究词汇知识对第二语言能力的作用，许多研究者开展了相关的实证研究。但是他们的研究结论各不相同。本论文从词汇知识的两个基本维度——广度和深度入手，就词汇知识和二语能力的关系进行了实证调查，旨在帮助二语学习者和研究者更好地理解词汇知识的地位和作用。 词汇知识一直以来都被认为是多维度的，涵盖了很多方面的知识。作为词汇知识系统里基本的两个维度，广度和深度即是本论文进行研究的着力点。本研究共有83名大学二年级非英语专业学生参与。为了对他们的词汇知识和英语水平做出最可靠的统计，所有83名同学均接受了三次语言测试，即词汇广度知识测试、词汇深度知识测试和英语水平测试。三项测试的得分输入电脑作为原始数据并通过SPSS13．0进行分析。调查结果显示：词汇广度和深度分别与二语能力呈显著正相关关系；广度和深度均对二语综合能力和各分项能力有预测能力，而广度的预测能力更是强于深度；对于总体调查对象来说，广度和深度有显著正相关关系，但该相关关系因受试者广度水平不同而不同。 基于以上结论，本文提出应更加重视词汇知识的提高在第二语言习得过程中的重要作用。作为很有效的二语水平预测因子，词汇深度知识不应继续受到忽视。二语学习者和教师不但应将广度知识，还应将深度知识融合进学习和教学过程。
