Using the Hello English Application in the EFL Classroom: Its Efficacy in Helping Students to Master Vocabulary

Integrating technology as a teaching media in language learning has been widely promoted by teaching practitioners. Mobile Assisted Language Learning (MALL) is among the most popular approaches used in EFL classrooms and has been reported in some studies to be beneficial in supporting students' language learning process. This study aimed to determine whether employing MALL through the Hello English (HE) application as a teaching media could significantly affect the mastery of vocabulary of eighth grade students in an English as a Foreign Language (EFL) Junior High School ( JHS) classroom. Using a quantitative approach with a quasi-experimental design, this study presented the numerical data collected through a multiple-choice test. In analyzing the data, t-tests were employed with a 5% (0.05) significance level using the SPSS statistical test tools v.20. According to the results, the HE application had a significant effect on the students' mastery of the vocabulary, and so it is recommended that the HE application be used as a tool in the English language teaching and learning process.
