THE EFFECTIVENESS OF USING @JAYFUJIWARA TIKTOK ACCOUNT TO IMPROVE STUDENTS’ VOCABULARY MASTERY

Abstract

The integration of digital learning media has created opportunities to enhance English vocabulary mastery through engaging and accessible platforms. This study aimed to examine the effectiveness of the @jayfujiwara TikTok account in improving the vocabulary mastery of eleventh-grade students at SMK Negeri 1 Dukuhturi. The study employed a quantitative approach using an experimental pre-test–post-test design involving 72 students divided into an experimental group and a control group through cluster random sampling. Data were collected using vocabulary pre-tests and post-tests consisting of 35 multiple-choice and 5 short-answer items, then analyzed using descriptive statistics, the Shapiro–Wilk normality test, Levene’s homogeneity test, paired-samples t-test, and independent-samples t-test. The findings revealed that the experimental group demonstrated significantly greater improvement in vocabulary mastery than the control group, with the independent-samples t-test showing a significance value of 0.000 (p < 0.05). These results indicate that the use of the @jayfujiwara TikTok account effectively enhances students’ vocabulary mastery. The study concludes that integrating short educational videos based on a microlearning approach can serve as an effective digital learning strategy to improve vocabulary acquisition while increasing students’ engagement and motivation in English language learning.
