Pengembangan Media Pembelajaran Berbantuan TikTok untuk Meningkatkan Pemahaman Operasi Bilangan Bulat Siswa SMP

Abstract

This study addresses the persistent challenge of low achievement in integer operations among junior high school students, as evidenced by 84% of seventh-grade students at SMP Negeri 17 Tasikmalaya failing to meet learning objectives in this topic. Recognizing the widespread use of digital technology and social media—specifically TikTok—among Generation Z students, this research aims to develop, implement, and evaluate an innovative learning media based on the TikTok application to enhance understanding of integer operations. Employing a research and development methodology guided by the ADDIE model (Analysis, Design, Development, Implementation, Evaluation), the study involved expert validation, small and large group trials, and systematic data collection through questionnaires and achievement tests. The TikTok-based learning media, featuring structured video content, interactive exercises, and engaging visualizations, was validated by subject and media experts as suitable and highly appropriate for instructional use (80% and 90% feasibility, respectively). Student responses indicated a very positive reception (82% in the large group trial), with notable improvements in engagement, comprehension, and motivation. Post-implementation assessment showed a significant increase in learning outcomes, with 89% of students meeting the predetermined mastery criteria, compared to only 16% prior to the intervention. These results demonstrate that the integration of TikTok as a learning medium effectively addresses the difficulties students face with abstract mathematical concepts and fosters a more engaging, flexible, and accessible learning environment. The study recommends broader adoption of social media-based learning tools to support mathematics education and calls for further research on their application across diverse topics and educational settings.
