title: IMPROVING STUDENTS’ VOCABULARY MASTERY THROUGH SHORT VIDEOS AS LEARNING MEDIA AT NURUL IMAN ISLAMIC BOARDING SCHOOL PURWOREJO creator: MUHAMMAD, MIFTAHUL LUTHFI RAFLI subject: 370 Pendidikan subject: 420 Bahasa Inggris dan Inggris kuno (Anglo-Saxon) description: This study investigates the effectiveness of short videos as a teaching media to enhance students' vocabulary mastery at Nurul Iman Islamic Boarding School Purworejo. Employing a quantitative approach with a one-group pre-test and posttest design, 20 students from Class 9A were selected as participants. A vocabulary test served as the primary instrument for data collection, measuring student performance before and after the treatment. The findings revealed a significant improvement in vocabulary mastery, with mean rank increasing from 11.30 in the pre-test to 29.70 in the post-test, yielding a gain of 18.40 points. Statistical analysis confirmed the improvement's significance (p-value < 0.05). The use of short videos not only facilitated effective vocabulary acquisition but also increased student engagement and interest in the learning process. These results underscore the potential of integrating multimedia tools into language education, particularly in enhancing vocabulary learning outcomes in Islamic boarding school settings.
