Exploring the Influence of Microsoft Copilot on the Writing Proficiency of ESL Learners in Academic Writing

The increasing use of Generative AI in education has transformed academic writing support for ESL learners. This study examines the impact of Microsoft Copilot, an Artificial Intelligence-powered writing assistant, on the academic writing performance of pre-university students preparing for MUET. Using a quasi-experimental mixed-methods approach, the study compares learners who used Microsoft Copilot with those who followed conventional writing practices. Findings indicate that Copilot enhanced learners' academic writing by improving grammar, vocabulary, idea development, and text organization. Participants also reported greater confidence and motivation due to the tool's instant feedback and writing assistance. However, concerns regarding overreliance on AI-generated content and academic integrity were identified. The study highlights the potential of Microsoft Copilot as a supplementary tool for improving ESL academic writing while emphasizing the importance of ethical AI use and responsible pedagogical integration.
