Abstract


This study evaluated the effectiveness of the “My English Study” TikTok channel in improving the vocabulary mastery of eighth-grade students at SMP Negeri 1 Tilongkabila. Using a quantitative one-group pre-test and post-test experimental design, the study involved 26 purposively selected students. Data were collected through objective tests assessing nouns and adjectives in descriptive texts and analyzed using a paired samples t-test. The results showed a significant improvement in students’ vocabulary achievement, with the mean score increasing from 40.92% in the pre-test (low category) to 74.92% in the post-test (high category). Adjective mastery reached 96.50% accuracy, while noun mastery improved to 57.97%. Statistical analysis revealed a t-value of 18.686 and a p-value of 0.000 (p < 0.05), indicating a significant difference between pre-test and post-test results. Therefore, the study concludes that the “My English Study” TikTok channel is an effective digital learning medium for enhancing vocabulary acquisition, motivation, and engagement among students.
