2006-2011二语习得研究热点与前沿的可视化分析

Visualization of Focuses and Fronts in Second Language Acquisition Research during 2006-2011

本研究运用词频统计方法对2006-2011二语习得研究的关键词进行分析统计,总结出近年来该领域的研究热点与前沿,同时借助信息可视化技术绘制了该领域近年来的科学知识图谱。结果表明,2006-2011二语习得研究的热点和前沿如下:重视句法层面的习得研究;重视对中介语语言学特征的描写;重视对学习理论和学习者个体差异的研究;重视学科间的交叉研究;重视基于课堂的研究,尤其是课堂反馈研究;涉及语种范围广,其中以对英语、西班牙语和汉语的习得研究居多。这些发现可以帮助二语习得研究者及时把握学科发展的热点和前沿,并对探寻与确定研究方向有一定的参考价值。

The paper adopts word frequency and co-word analysis in an attempt to get the research focuses and fronts in SLA by analyzing the keywords in articles published during 2006-2011,and also uses visualization tool to draw the mapping knowledge domains of recent SLA research.The survey reveals that the focuses and fronts are mainly about SLA at the syntactic level,the description of interlanguage's features,and classroom-based language education.It could be seen that the cross-over studies between SLA and other disciplines,such as cognition science and neuroscience,cover many areas,displaying SLA's interdisciplinary feature.This study,therefore,is a good reference for SLA researchers to quickly get access to the research fronts and focuses,and then choose their own research interests.
