Analyzing Discourse Patterns in ChatGPT-Generated IELTS Writing Task 2 Essays: A Discourse Analysis Approach

Abstract This study examines the discourse features of ChatGPT-generated IELTS Writing Task 2 essays, with a focus on the specific characteristics associated with band descriptors for scores of 6 and 7.Utilizing discourse and content analyses approaches, the studyexamines coherence, cohesion, argument structure, and lexical resource to understand the discourse characteristics indicative of different proficiency levels. Findings reveal that band 6 essays exhibit basic coherence with abrupt transitions and limited use of cohesive devices which result in a more linear argument structure and simpler lexical choices. Conversely, band 7 essays demonstrate a clearer progression of ideas, enhanced cohesion through varied cohesive devices, and a more complex argument structure that effectively integrates counterarguments and depth of analysis. These discourse patterns underscore the potential for AI-generated texts to model proficiency levels in writing and serve as pedagogical tools to improve learner outcomes. By highlighting the discourse elements critical to achieving higher band scores, this study contributes valuable insights into AI’s role in supporting language learning and academic writing proficiency.
