Research on the Role of Large Language Models in Enhancing English Learners' Writing Skills: A Literature Review

Abstract

This paper presents a systematic review of the research progress and practical applications of Large Language Models (LLMs) in supporting English writing instruction. It examines how key technologies, such as natural language generation and long-text optimization, contribute to writing pedagogy, outlines the dual supportive role of LLMs across the writing process along with their personalized instructional pathways, and evaluates their strengths and limitations. The study also explores the potential of LLMs in reducing writing anxiety. Lastly, it highlights the current scarcity of research focused specifically on children and adolescents and proposes future research directions, including age-appropriate LLM application strategies, cross-cultural considerations, and investigations into long-term outcomes.
