Investigating the Impact of Mobile Vocabulary Application on Vocabulary Learning Among Saudi ESL Learners With Different Learning Styles

This study explores the impact of the mobile vocabulary application Kahoot on vocabulary learning among Saudi ESL learners, Kahoot has the advantage of addressing individual learning styles (visual, auditory, kinesthetic, read/write). Using a quasi-experimental design, 20 female students were divided into an experimental group that received Kahoot-based instruction and a control group that followed traditional methods. Pre- and post-test vocabulary scores were analyzed to assess learning gains, and the VARK questionnaire determined learning style preferences.The results revealed that the experimental group significantly outperformed the control group in post-test vocabulary scores, with a large effect size (Cohen’s d = 0.96), demonstrating the effectiveness of Kahoot in enhancing vocabulary learning. Although learning styles were not significant moderators of app effectiveness, correlations suggested varied benefits across styles.The findings suggest that mobile applications like Kahoot can serve as practical tools for vocabulary instruction in ESL contexts, benefiting learners regardless of their learning style. The study concludes with recommendations for integrating mobile-assisted learning into classroom practices to enhance vocabulary learning.
