词汇附带习得中投入量假设研究的元分析

A Meta-analysis on the Study of Involvement Load Hypothesis in Vocabulary Incidental Acquisition

采用元分析的方法,系统分析了11篇关于输出任务对二语或外语附带词汇学习影响的论文。以输出任务的类型和任务的时间作为主要的中介变量。结果表明,完成输出任务的语言学习者的表现要优于仅阅读文本的语言学习者。此外,任务时间对词汇学习也有积极影响。结果基本支持了投入量假设,即高投入量能够使得学习者习得了更多的词汇。

This study uses a meta-analysis method to systematically analyze 11 papers on the impact of output tasks on vocabulary learning in second or foreign languages.The type of output task and the time of the task are used as the main mediator variables.The results show that the language learners who complete the output task perform better than the language learners who only read the text.In addition,task time has a positive impact on vocabulary learning.The results generally support the Involvement Load Hypothesis that high involvement load can help learners acquire more vocabulary.
