The impact of mobile-based dynamic assessment on improving EFL oral accuracy

Although a number of studies have reported on the positive effects of Mobile Assisted Language Learning (MALL) in the development of students’ language learning, few studies have examined language assessment, particularly Dynamic Assessment (DA), in this area. Accordingly, this study aims at investigating the effect of Mobile-based Dynamic Assessment (MDA) on English as a Foreign Language (EFL) learners’ oral accuracy. To this end, 120 students from Iran were randomly assigned to two experimental groups and one control group, each consisting of 40 participants. The learners in the experimental groups accomplished eight communicative tasks through DA in two separate contexts: MDA through text-chat context and MDA through voice-chat context. Students’ oral performance was recorded and analysed to measure the accuracy of speech production. The analysis of the data showed that the experimental groups who received MDA significantly outperformed the control group on the post-test. The findings point to the effectiveness of MDA in the development of EFL students’ oral accuracy.
