THE USE OF MOBILE APPLICATIONS IN ESL VOCABULARY ACQUISITION

Abstract

This thesis investigates the effectiveness of mobile applications in enhancing English as a Second Language (ESL) learners’ vocabulary acquisition. With the growing integration of technology into language education, mobile-assisted language learning (MALL) has become a significant tool for improving vocabulary knowledge. The study focuses on how specific mobile applications contribute to learning outcomes among ESL learners, evaluating both learner engagement and vocabulary retention. A mixed-methods approach was employed, combining quantitative pre- and post-tests with qualitative interviews to assess learners’ progress and experiences. Participants consisted of intermediate-level ESL students who used selected vocabulary learning apps over a four-week period. Findings revealed that mobile applications significantly improve vocabulary acquisition through interactive features, spaced repetition, and multimedia content. The flexibility and accessibility of mobile learning environments further enhanced learners’ motivation and autonomy.
