The Effects of Using Grammarly’s Artificial Intelligence (AI) Application to Improve EFL Undergraduate Students’ Writing Skills
Main Article Content
Abstract
This study investigated the impact of Grammarly, an AI-powered writing assistant, on the writing skills of undergraduate EFL students. The mixed-methods study employed quantitative and qualitative analyses to evaluate Grammarly’s impact on students’ writing performance. The study employed cluster sampling to select 126 third-year students from a population of 496 at Nakhon Pathom Rajabhat University. The results demonstrated that Grammarly significantly improved students’ writing proficiency in various aspects, including spelling, grammar, punctuation, sentence structure, vocabulary, and style. The average scores of the students showed substantial improvement in all assessed categories. In addition, group interviews revealed that most students viewed Grammarly as a valuable tool for fostering independent learning. This study, therefore, suggests that integrating AI-powered tools such as Grammarly can complement traditional teaching methods, address limitations, and enhance the overall learning experience in English language education
