EXPLORING ENGLISH VOCABULARY LEARNING STRATEGIES THROUGH AI INTEGRATION OF THAI UNIVERSITY STUDENTS: A CASE STUDY

Abstract

This study aimed to explore the English vocabulary learning strategies of Thai university students with an emphasis on the integration of Artificial Intelligence (AI) tools. Specifically, the research sought to (1) identify the vocabulary learning strategies employed by students, (2) examine how AI tools such as ChatGPT, Quizlet, and Grammarly were integrated into their learning practices, and (3) evaluate their perceptions of AI-assisted strategies compared with traditional methods. Data were collected through a voluntary online survey conducted in March until April 2025 with 32 informants, all undergraduate students majoring in Business English at a private university in Bangkok. The survey included open-ended questions, and the responses were analyzed qualitatively using thematic analysis to capture recurring patterns and themes. The findings revealed that students combined traditional strategies (e.g., reading, note-taking, peer discussions) with technology-based approaches, highlighting a dynamic blend of methods. ChatGPT emerged as the most widely adopted AI tool, followed by Grammarly and Quizlet, each serving complementary purposes in vocabulary acquisition. Students perceived AI-assisted strategies as highly effective, particularly in providing instant feedback, contextualized examples, and enhanced motivation, though they continued to value traditional practices for deeper comprehension and authentic interaction. The study contributes to the growing body of research on AI-assisted vocabulary learning in EFL contexts by offering insights into how Thai undergraduates integrate emerging technologies with established learning strategies. The study contributed to EFL pedagogy by highlighting practical ways to integrate AI tools into vocabulary instruction while preserving the value of traditional strategies.
