Learning Mathematics in the Digital Era: An Analysis of High School Students’ Interaction Patterns through TikTok

The rapid growth of social media has reshaped students’ learning behaviors and interaction patterns, including in mathematics education. TikTok, as a short-form video platform widely used by adolescents, offers unique affordances for micro-learning, algorithm-driven content exposure, and non-linear interaction. Although previous studies have demonstrated that TikTok can improve students’ mathematics achievement, motivation, and interest, limited attention has been paid to the underlying social-cognitive interaction processes through which mathematical understanding is constructed. This study aims to analyze high school students’ interaction patterns in learning mathematics through TikTok by examining how digital interactions support mathematical sense-making rather than merely learning outcomes.This study employed a descriptive qualitative approach involving four eleventh-grade students at MAN 2 Palu, Indonesia, selected through purposive sampling. Data were collected through observations of students’ TikTok activities and semi-structured interviews. The analysis was guided by Moore’s interaction model, encompassing student–content, student–creator interactions, and student–student interactions, adapted to the non-linear and algorithmic context of TikTok. The findings reveal three distinct interaction patterns: high, moderate, and low. Students with high interaction levels actively engaged across all three interaction dimensions, demonstrating reflective learning, digital self-efficacy, and autonomous regulation of mathematical learning. In contrast, students with moderate and low interaction levels primarily engaged in passive content consumption, with limited social and pedagogical interaction, positioning TikTok more as an entertainment platform than a learning space. These differences indicate that mathematical sense-making on TikTok is strongly mediated by the quality of interaction rather than the intensity of platform use alone. This study highlights that TikTok’s educational potential lies not merely in its effectiveness in improving scores, but in how interaction quality shapes students’ cognitive engagement and meaning-making processes in mathematics learning. The findings suggest that integrating structured interaction designs and fostering digital self-efficacy are crucial for maximizing the pedagogical value of social media-based mathematics learning.Pembelajaran Matematika di Era Digital: Analisis Pola Interaksi Peserta Didik SMA melalui Media TikTokABSTRAKPerkembangan media sosial telah mengubah cara siswa mengakses, memaknai, dan berinteraksi dengan pengetahuan matematika. TikTok, sebagai platform video pendek berbasis algoritma, menawarkan karakteristik pembelajaran yang berbeda dari platform digital konvensional karena menggabungkan konten ringkas, atensi cepat, serta interaksi sosial yang bersifat spontan dan tidak linier. Namun, masih terbatas penelitian yang menjelaskan bagaimana pola interaksi siswa di TikTok berkontribusi terhadap proses mathematical sense-making, bukan sekadar peningkatan hasil belajar. Penelitian ini bertujuan untuk menganalisis pola interaksi siswa SMA dalam pembelajaran matematika melalui TikTok dengan menggunakan Model Interaksi Moore yang mencakup student–content, student–creator interaction, dan student–student interaction. Penelitian menggunakan pendekatan kualitatif deskriptif dengan empat siswa kelas XI MAN 2 Kota Palu yang dipilih melalui teknik purposive sampling. Data dikumpulkan melalui observasi aktivitas TikTok dan wawancara semi-terstruktur, kemudian dianalisis secara tematik. Hasil penelitian menunjukkan tiga kategori pola interaksi, yaitu tinggi, sedang, dan rendah. Siswa dengan interaksi tinggi aktif pada ketiga dimensi Moore, memanfaatkan fitur TikTok seperti video pendek, komentar, Live, dan pesan langsung untuk membangun pemahaman konsep, merefleksikan strategi penyelesaian soal, serta mendiskusikan ide matematika secara kolaboratif. Sebaliknya, siswa dengan interaksi rendah cenderung hanya mengakses konten secara pasif dan tidak terlibat dalam proses negosiasi makna matematis. Temuan ini menunjukkan bahwa perbedaan kualitas interaksi digital berpengaruh signifikan terhadap cara siswa membangun pemahaman matematika di lingkungan media sosial. Disimpulkan bahwa keunikan TikTok sebagai ruang belajar tidak terletak pada kontennya semata, melainkan pada pola interaksi sosial-kognitif yang terbentuk melalui integrasi algoritma, micro-learning, dan jejaring sosial. Penelitian ini menegaskan pentingnya menggeser fokus kajian dari efektivitas hasil belajar menuju analisis proses interaksi digital sebagai kunci pengembangan pembelajaran matematika berbasis media sosial.Kata Kunci :pola interaksi; pembelajaran matematika; siswa SMA; TikTo

Rekonstruksi Sejarah Dan Transformasi Cagar Budaya Istana Almukarramah Kesultanan Sintang

The Almukarramah Palace of the Sintang Sultanate is a Cultural Heritage site that must be preserved. Periodic research is one of the efforts to support its preservation. This study aims to reconstruct the historical narrative based on newly discovered data and to describe the current condition of the palace building. The local community is expected to be encouraged to utilize the palace, particularly institutions engaged in history, education, and tourism. This research uses a qualitative method with historical and architectural approaches. The historical approach is used to reconstruct historical information, including heuristics, verification, interpretation, and historiography. The architectural approach is applied to describe the physical form of the object. Primary and secondary data were collected through observation, interviews, and literature studies. The results show that the palace has stood in the Kampung Raja area since Sintang was a Hindu kingdom. However, the structure currently standing was built when Sintang became an Islamic kingdom, specifically during the reign of Panembahan Raden Abdul Bahri Danu Perdana Al-Mukarram Kesuma Negara IV. The construction of the Sintang Sultanate Palace was full of dynamics, ranging from disputes between the Panembahan and the Dutch colonial government to the sinking of a ship carrying construction materials. Observations also revealed many historical objects around the palace. One of the new contributions of this research is the documentation of the changes in the building’s function and its renovation history after Sintang's integration into Indonesia

Exploring Students’ Long-term Retention and Conceptual Mastery in Two-Dimensional Kinematics: A Descriptive Study

This study aims to comprehensively describe students’ understanding of projectile motion by analyzing the results of three essay-type questions. These questions were designed to measure conceptual understanding of the trajectory, the ability to separate horizontal and vertical components of motion, and the skill to apply basic quantitative calculations within the context of two-dimensional kinematics. The research employed a quantitative descriptive method, with data collected through written tests and direct observation of students’ answer patterns. This approach enabled the identification of dominant types of errors, both conceptual and procedural, thus providing a thorough picture of students’ overall understanding. A total of 67 eleventh-grade students participated in this study. All responses were classified into five accuracy categories: completely incorrect, partially correct, one correct, two correct, and entirely correct. Data analysis was carried out using percentage techniques to clearly and quantitatively present the distribution of students’ abilities in each category. The findings show that 74.63% of students still struggle to solve projectile-motion problems, particularly in separating the initial velocity components and determining an object’s position at a given time—tasks that require simultaneous understanding of vector concepts and motion equations. Only 7.46% of students were able to answer all questions correctly, while the remaining 17.91% fell into the partially correct to one-correct-answer categories. Based on these results, it can be concluded that students’ understanding of the basic concepts of projectile motion remains low and tends to rely on formula memorization rather than conceptual comprehension. Therefore, more systematic, contextual, and concept-focused learning strategies are needed to improve mastery of two-dimensional kinematics more effectively.Eksplorasi Retensi Jangka Panjang dan Penguasaan Konseptual Siswa dalam Kinematika Dua Dimensi: Studi ObservasiABSTRAKPenelitian ini bertujuan untuk mendeskripsikan secara komprehensif tingkat pemahaman siswa terhadap materi gerak parabola melalui analisis mendalam terhadap hasil pengerjaan tiga butir soal uraian.
