Enhancing English Vocabulary Learning Strategy Use with e-Portfolio

本研究设计并开发了一个词汇学习电子档案袋，旨在调查日本英语学习者的策略使用情况，并提高他们的自主学习策略使用水平。学习者可以通过记录词汇信息、监控理解和基于电子档案袋中词汇熟悉度的元认知控制策略的使用来促进词汇学习策略的使用。通过在日本两所私立大学为期10周的英语课堂上的调查，研究表明，在七种词汇学习策略中，笔记策略、口语练习策略和语言暴露策略的使用率显著提高。实验结果还表明，学生通过记录、编辑电子学档上的词汇信息和元认知监控，获得了有针对性的词汇知识。计划在安排版权事宜后，免费向公众开放电子作品集。

A vocabulary learning e-portfolio was designed and developed for the study to investigate Japanese English learners' strategy use, and to enhance their self-controlled learning strategy use. Learners are expected to facilitate their vocabulary learning strategy use by recording lexical information, monitoring understanding, and controlling their strategy use metacognitively based on word familiarity on the e-portfolio. Through 10-week English classes at two Japanese private universities, the participants in the study showed a significant increase in the use of note-taking strategy, oral rehearsal strategy, and language exposure strategy out of seven vocabulary learning strategies measured by a questionnaire. The results also showed that they gained targeted vocabulary knowledge by recording and editing lexical information and metacognitive monitoring on the e-portfolio. The e-portfolio is planned to be open to public for free of charge after copyright issues are arranged.
