Investigating the effectiveness of practicing English conversation with ChatGPT in improving non-English majored students’ English speaking skills at Nguyen Tat Thanh University

This study aimed to investigate the effectiveness of practicing English conversations with ChatGPT to enhance speaking skills of English as a Foreign Language (EFL) learners at Nguyen Tat Thanh University, specifically focusing on four key criteria: conversational fluency, pronunciation, vocabulary use, and grammatical accuracy. In this study, 60 students were divided into six groups for a quasi-experimental design with a combination between non-equivalent groups design and pretest-posttest design. Four groups were trained with ChatGPT for eight weeks, while two control groups were not. Speaking abilities were measured through pretest, mid-test, and posttest assessments. The findings revealed significant improvements in conversational fluency, vocabulary, and grammar for the ChatGPT-trained groups, while pronunciation showed minimal progress. These results suggest that integrating ChatGPT into English teaching curricula could help non-English majored students at Nguyen Tat Thanh University enhance their English communication skills.
