THE ROLE OF LEXICAL CHUNKS IN DEVELOPING GRAMMATICAL ACCURACY IN EFL LEARNERS

This study explores the role of lexical chunks in developing grammatical accuracy among English as a foreign language (EFL) learners. Unlike traditional approaches that focus on isolated grammar instruction, the lexical approach emphasizes learning prefabricated units of language, such as collocations, fixed expressions, and common phrases. A quasi-experimental study was conducted with two groups of intermediate-level students: one received conventional grammar teaching, while the other engaged in activities based on lexical chunks. Pre-tests and post-tests measured improvements in grammatical accuracy and fluency. The findings indicate that learners exposed to lexical chunks made fewer grammatical errors and produced more natural, native-like language in both speaking and writing tasks. The study highlights the importance of integrating vocabulary and grammar through meaningful, contextualized practice. These results suggest that lexical chunk instruction can enhance communicative competence and should be incorporated alongside traditional grammar teaching in EFL classrooms to improve overall language proficiency.本研究探讨了语块（lexical chunks）在外语英语（English as a foreign language, EFL）学习者语法准确性培养中的作用。相较于聚焦孤立语法讲授的传统教学路径，语块教学法更强调学习预制的语言单元，诸如搭配、固定表达与常用短语等。本研究针对两组中级水平学习者开展准实验研究：一组接受传统语法教学，另一组则参与基于语块的学习活动。研究通过前测与后测，对学习者在语法准确性与语言流利度方面的提升情况进行了评估。结果显示，接受语块教学的学习者所犯语法错误更少，且在口语与写作任务中产出的语言更为自然地道，贴合母语使用者的表达习惯。本研究凸显了通过兼具意义性与情境化的练习整合词汇与语法的重要价值。上述研究结果表明，语块教学可有效提升学习者的交际能力，且应与传统语法教学相结合，应用于外语英语课堂，以全面提升学习者的整体语言水平。
