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，以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能力。期望学习者通过记录词汇信息、监控理解和元认知控制词汇学习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进行为期10周的英语课程，研究参与者发现，在问卷调查中测量的7种词汇学习策略中，记笔记策略、口语排练策略和语言暴露策略的使用显著增加。通过对词汇信息的记录和编辑以及对电子档案的元认知监测，学生获得了有针对性的词汇知识。电子档案计划在安排版权事宜后，免费向公众开放。

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.
