Abstract

Transformasi digital dalam pendidikan menjadi salah satu strategi utama untuk meningkatkan kualitas pembelajaran sains pada abad ke-21. Integrasi pendekatan Science, Technology, Engineering, and Mathematics (STEM) dengan teknologi digital diyakini mampu mengembangkan kemampuan berpikir kritis, pemecahan masalah, kreativitas, serta literasi sains peserta didik. Meskipun demikian, implementasi pembelajaran berbasis transformasi digital dan STEM masih menghadapi berbagai tantangan, khususnya pada aspek kesiapan guru, infrastruktur teknologi, dan efektivitas penerapannya dalam meningkatkan literasi sains. Penelitian ini bertujuan untuk menganalisis tren penelitian, bentuk implementasi, efektivitas, serta tantangan penerapan transformasi digital berbasis STEM dalam meningkatkan literasi sains siswa sekolah menengah pertama melalui pendekatan Systematic Literature Review (SLR). Metode penelitian mengacu pada pedoman PRISMA 2020 dengan melakukan penelusuran artikel pada basis data Scopus, ScienceDirect, SpringerLink, Taylor & Francis, dan Google Scholar yang dipublikasikan selama periode 2020–2026. Berdasarkan proses identifikasi, penyaringan, uji kelayakan, dan inklusi, diperoleh 35 artikel yang memenuhi kriteria analisis. Hasil kajian menunjukkan bahwa pembelajaran berbasis transformasi digital yang dipadukan dengan pendekatan STEM secara konsisten memberikan dampak positif terhadap peningkatan literasi sains, kemampuan berpikir kritis, pemecahan masalah, kolaborasi, kreativitas, serta keterampilan abad ke-21 peserta didik. Media digital yang paling banyak digunakan meliputi Learning Management System (LMS), simulasi virtual, laboratorium virtual, aplikasi interaktif, multimedia pembelajaran, dan platform berbasis kecerdasan buatan (Artificial Intelligence). Namun demikian, implementasi masih menghadapi kendala berupa keterbatasan infrastruktur teknologi, rendahnya kompetensi digital pendidik, serta kesenjangan akses teknologi antarwilayah. Oleh karena itu, diperlukan penguatan kebijakan transformasi digital, peningkatan kompetensi guru, serta pengembangan model pembelajaran STEM berbasis teknologi yang kontekstual dan berkelanjutan untuk mendukung peningkatan kualitas pendidikan sains di Indonesia.

Abstract

Abstract This study aims to examine mathematical concepts embedded in the practice of Toroi Lado Dahha in Lamboya indigenous community, West Sumba. The study is motivated by the importance of exploring mathematics embedded in local culture as part of ethnomathematics. This research employed a qualitative ethnographic approach through in-depth interviews with traditional leaders (Rato). The results show that Toroi Lado Dahha contains mathematical concepts such as basic arithmetic, number sequences, discrete time functions, and lunar calendar systems. The determination of ritual time is conducted through forward counting from the full moon phase and by observing the emergence of nyale, a type of sea worm that serves as the main indicator for Pasola timing. Furthermore, the system is not fixed but adaptive to natural conditions and cultural decisions. This study reveals that mathematics in Lamboya society is implicit and integrated with language, culture, and daily practices. These findings are important for developing contextual mathematics learning based on local culture. Keywords: Ethnomathematics, Toroi Lado Dahha, Counting System, Auspicious Days, Sumba Culture

Abstract

The Education Report presents learning outcomes down to the content domain level, yet schools rarely use it to diagnose weaknesses in student numeracy, and even less so in geometry. This study mapped the geometry achievement profile in AKM Numeracy, traced the factors accompanying low achievement, and formulated recommendations for improving instruction. An explanatory sequential mixed methods design was used. The first phase analysed indicators from the 2025 Education Report of SMP Negeri 10 Tual using descriptive quantitative analysis. The second phase explained the resulting patterns through semi-structured interviews with students and mathematics teachers, analysed thematically following the interactive model of Miles, Huberman, and Saldana. The quantitative phase showed that 79.17% of students had not reached the minimum numeracy competency and that the geometry score fell from 50.64 in 2024 to 47.51 in 2025. The lowest achievement occurred in knowing (40.68) and applying (46.53), while reasoning rose by 3.28 points. Interviews with students and teachers indicated that the main difficulties stem from poor reading of visual representations, mastery of shape properties relying solely on rote memorization, and limited use of interactive learning media in the classroom. The Education Report can therefore serve as a diagnostic instrument supporting data-driven decision making for geometry learning in junior secondary schools.
