Abstract

This study explores the utility of ChatGPT, a large language model (LLM), for automated linguistic analysis in English as a Second Language (ESL) contexts. It examines whether ChatGPT can generate quantitative metrics, analyze learner prompts, assess vocabulary exposure, and evaluate questioning strategies. Ninety-nine CEFR A1 learners completed two structured chat tasks with ChatGPT. Data analysis was conducted using structured prompts and calibration procedures within ChatGPT-4o. Quantitative metrics (e.g., word counts, question types, sentence complexity) and qualitative classifications (e.g., vocabulary themes, follow-on question types) were generated by the model, formatted in .csv outputs, and partially verified through human-in-the-loop review. Results of transcript analysis indicate that ChatGPT effectively produces useful quantitative data including measures of sentence complexity and prompting skills. It also offers qualitative analysis of vocabulary exposure and investigative themes. Analysis of questioning skills revealed student ‘Wh’ word use and follow-on inquiry patterns. Despite noted strengths, ChatGPT showed limitations in analysis consistency, suggesting the need for teacher oversight. Recommendations include training educators in prompt-based analysis, guiding students in metric interpretation, and further validating LLM-generated data.
