Abstract

This study aims to analyze the relationship between the intensity of TikTok social media use and the mathematics learning achievement of MTs students in Social Arithmetic. This study uses a quantitative, ex post facto design, so the researcher does not provide direct treatment but rather examines phenomena that have occurred naturally. The study population comprised all seventh-grade students at MTs Raudlatul Uluum Aek Nabara, and samples were selected through purposive sampling, namely two groups based on TikTok usage intensity (high and low). Data collection was conducted using a questionnaire to assess the intensity of TikTok use and a test to measure mathematics achievement. Data analysis included normality tests, homogeneity tests, Independent-Samples t-tests, and effect size estimates using Cohen's d. The results showed a significant difference between the two groups (p = 0.007 < 0.05). The average score of students with low TikTok usage intensity (8.357) was higher than that of the high-intensity group (6). The effect size of 0.72 indicates that the difference falls in the moderate range, so it has practical meaning in the learning context. These findings suggest a relationship between the intensity of TikTok use and students' math achievement. The higher the intensity of TikTok use, the lower the student's math achievement tends to be. It is hoped that the results of this study will serve as a reference for educators and parents in managing students' social media use more wisely and effectively.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan karakteristik hasil belajar siswa pada materi vektor ketika diterapkan pembelajaran berbasis visual. Penelitian menggunakan pendekatan kualitatif deskriptif dengan desain studi kasus pada 30 siswa kelas X SMA Data dikumpulkan melalui tes hasil belajar vektor, observasi aktivitas belajar, dan wawancara semi‑terstruktur. Hasil menunjukkan bahwa pembelajaran berbasis visual (diagram vektor, animasi, GeoGebra, dan modul visual) meningkatkan rerata skor dari 58,2 pada pre‑test menjadi 82,4 pada post‑test, dengan persentase ketuntasan klasikal naik dari 43,3% menjadi 86,7%. Analisis jawaban uraian menunjukkan pergeseran dari pemahaman prosedural ke pemahaman konseptual, serta peningkatan kemampuan visualisasi spasial. Implikasinya, pembelajaran vektor sebaiknya dirancang secara visual dan bertahap dengan scaffolding untuk membantu siswa membangun konsep vektor secara utuh.
