Abstract

The present study investigates GenAI-mediated vocabulary learning strategies (VLS) among Chinese university English learners by integrating measurement validation and person-centered analysis. A sample of 593 Chinese EFL students completed a 24-item questionnaire assessing four strategy dimensions: AI-assisted lexical discovery, AI-supported lexical elaboration, AI-mediated metacognitive regulation, and AI-based lexical activation. Confirmatory factor analysis supported a correlated four-factor structure with strong reliability and acceptable convergent validity, although high inter-factor correlations suggested closely integrated constructs. Latent profile analysis identified three learner groups, including low-to-moderate, moderate-to-high, and high strategy users. Profile comparisons revealed that higher-use groups reported greater AI experience, higher self-rated proficiency, and stronger vocabulary-related performance. No significant differences were found for gender or year of study. The findings extend VLS research into AI-mediated contexts, highlighting the importance of strategic engagement and supporting a reconceptualization of vocabulary learning as a dynamic human–AI interactional process.
