Research and Empirical Analysis of English Writing Ability Strategies Based on Electronic Dictionaries

随着信息技术与教育深度融合，电子词典逐渐成为语言学习的重要载体。本研究通过文献分析研究方法，系统探讨电子词典对英语写作能力的作用机制。研究发现，电子词典收录的英语词汇不仅可以显著提升学生词汇多样性与句法复杂度，同时其即时反馈特性可以提高学生的学习效率，但是导致元认知策略使用率下降，其表现为词义推测能力弱化与篇章连贯性受损。基于此，本文提出，主张通过工具辅助与教学引导的协同机制，主张通过分阶段使用策略，优化电子词典在写作教学中的应用路径。本研究为信息化时代平衡工具便利性与认知参与度提供了理论依据，并为英语写作教学改革提出了可操作性实践方案。With the deep integration of information technology and education, electronic dictionaries have gradually become an important carrier for language learning. This study systematically explores the mechanism of the effect of electronic dictionaries on school students’ English writing ability through the research method of literature analysis. The study finds that the English words included in electronic dictionaries can significantly improve students' lexical diversity and syntactic complexity. At the same time, the immediate feedback feature of electronic dictionaries can enhance students' learning efficiency. However, it leads to a decrease in the utilization rate of metacognitive strategies, which is manifested as the weakening of the ability to infer word meanings and the impairment of text coherence. Based on this, this paper proposes to optimize the application path of electronic dictionaries in writing teaching through the collaborative mechanism of tool assistance and teaching guidance. This study provides a theoretical basis and practical inspiration for the reform of English writing teaching in the context of informatization.
