The research was motivated by the dominance of conventional teaching methods that led to low student motivation and passive participation in vocabulary learning. A quantitative approach with a quasiexperimental design was employed, involving seventh-grade Makkah as the experimental class and seventh-grade Madinah as the control class. The sample consisted of 29 students selected using total sampling technique. Data were collected through pre-test and post-test, then analyzed using Shapiro-Wilk normality test, Levene's homogeneity test, and Independent Samples t-test. The results showed that the post-test scores of the experimental class were significantly higher than those of the control class. The Independent Samples t-test yielded a t-value of 4.281 with a significance value of 0.000 (p \u003C 0. 05), indicating a significant difference between the two groups after the treatment. These findings demonstrate that the use of the Busuu application is effective in improving students' English vocabulary mastery. Based on the results, it can be concluded that the Busuu application has a significant effect on the English vocabulary mastery of seventh-grade students at Madrasah Tsanawiyah Nur Rahma in Bengkulu City. Therefore, the Busuu application can be used as Mobile-Assisted Language Learning (MALL)-based instructional media to support English vocabulary learning.  \nKeywords: Busuu application, Vocabulary Mastery, Mobile-Assisted Language Learning (MALL), Quasi-Experimental  \nA. Introduction  \nEnglish plays an important role asan international language used in global communication, education, science, and technology. In learning English as a foreign language (English as a Foreign Language-  \nEFL), vocabulary mastery becomes one of the most fundamental aspects because it supports the development of the four main language skills: listening, speaking, reading, and writing. According to Girmen and Kaya (2019), vocabulary mastery  \nforms the foundation for students to understand and produce language effectively.  \nSimilarly, Dhaifi et al. (2020) stated that vocabulary knowledge enhances communicative ability and functions as a key component in achieving language proficiency. Therefore, vocabulary learning not only emphasizes memorization but also involves meaningful practice that allows students to repeatedly use and understand new words in various contexts.  \nNevertheless, many EFL students still experience difficulties in mastering English vocabulary. In classroom practice, vocabulary learning is often carried out through conventional methods such as teacher explanations and word memorization without adequate interactive activities.  \nAs a result, students tend to become passive learners and show low motivation during the learning process. This condition is also found at MTs Nur Rahma Bengkulu. Based on observations and in-depth interviews with student teachers who  \ncarried out teaching practice at the  \nschool on January 9, 2026, the English teaching and learning process is still dominated by one-way lecturing in which the teacher explains the material while students mainly listen.  \nSuch learning con","cbCaicz1jKHZnsTq","https://ap.wps.com/l/cbCaicz1jKHZnsTq","pdf",205004,11,"English","# Abstract\n# A.
