摘要
The present study, using quantitative and qualitative analyses, aimed at delineating the interrelationship between the knowledge of metacognition and the regulation of metacognition, along with the role of learners＇ regulatory ability in mediating the effects of task-induced involvement load on word learning. A total of 60 university EFL students were recruited to the study. They first completed a checklist on metacognition and were then assigned to complete three tasks with varying degrees of involvement load followed by a vocabulary test. Of them, 12 students also participated in an interview. The results showed that the two main components of metacognition, i.e., the knowledge and regulation of metacognition, are closely and significantly correlated. The learners, assigned to four different ability groups （LK/LR, LK/HR, HK/LR, HK/HR）, were found to benefit most by engaging in a task with the highest involvement load. Despite the benefits, their regulatory ability mediated the effects of task-induced involvement load on word learning, which was corroborated by the interview results. The relevant implications for teaching and learning words through tasks are further discussed.
本研究使用了定量和定性的研究方法,旨在描述元认知知识和元认知控制之间的相关性,以及学习者元认知控制能力对投入量假设下词汇学习的影响。60名把英语作为外语学习的大学生参加了本研究。这些受试者首先完成一份元认知调查,随后他们参加了一项词汇测试,在词汇测试后受试者被要求完成三项投入量不一的任务。研究人员对其中的12名受试者进行了访谈调查。研究的结果表明元认知的两个重要组成部分,即元认知知识和元认知控制高度相关。依据元认知知识和元认知控制能力水平,学习者被分为四个组别。研究发现,尽管所有组别都从投入量最高的任务中受益最多,他们的元认知控制能力对投入量假设下的词汇学习效果具有一定的影响,这一点也在访谈结果中得到验证。最后,研究对通过投入量假设任务进行词汇教与学进行了进一步的探讨。
