MALL and EFL Learners’ Speaking: Impacts of Duolingo and WhatsApp Applications on Speaking Accuracy and Fluency

Regarding the importance of using MALL in learning English, this study aimed to investigate the effects of Duolingo and WhatsApp applications on developing the speaking accuracy and fluency of Iranian EFL learners. To fulfill this objective, three groups of Iranian intermediate EFL learners were selected as the participants of this research. After that, all groups took the speaking pretest and then received the treatment. One group was taught ten conversations from Family and Friends Book 5 using the Duolingo application, and the other group was taught the same conversations using the WhatsApp application. The third group, considered the control group (CG), was instructed on the conversations in a traditional classroom. After teaching the conversations, a speaking posttest was administered to all groups to compare their performances after the treatment. The collected data were analyzed using the one-way ANOVA test. The results revealed that two experimental groups (EGs) had better performances than the CG on the speaking posttest. In addition, the outcomes showed that two EGs performed similarly on their speaking posttests. Eventually, the conclusions and the pedagogical implications of this research were explained.
