The effects of mobile-assisted language learning: A meta-analysis of research studies published in Korea

Mobile-Assisted Language Learning (MALL) has long been used as a tool in teaching and learning English language. Since the mid-2000, there have been numerous studies on using MALL in Korea. These studies have revealed meaningful effects of MALL; however, the results have not been consistent, being dependent on the different research setting. This study conducted a meta-analysis of 32 studies published in Korea between 2006 and 2021. The four criteria for selecting target studies were: the year of publication, experimental studies, pre- and post- test methods, and the use of mobile devices for intervention. The findings of the meta-analysis showed that MALL did not have as large an effect as expected on language ability achievement. Overall effect size was .488 which is considered a moderate effect size. In addition, based on meta-ANOVA analysis, the school level and language skill areas caused a significant difference on the impact of MALL; for instance, university students (.906) and grammar (.698) showed relatively high effects on language ability achievement. Limitation and suggestions for further studies are presented.
