Abstract

Penelitian ini dimaksudkan untuk menganalisis efektivitas penerapan model pembelajaran Peer-Led Team Learning (PLTL) dalam meningkatkan kompetensi mahasiswa pada mata kuliah Aljabar Linier. Latar belakang penelitian didasarkan pada rendahnya partisipasi aktif dan pemahaman konsep mahasiswa terhadap materi Aljabar Linier yang bersifat abstrak. Penelitian ini dilakukan dengan pendekatan kuantitatif menggunakan desain kuasi-eksperimental. Subjek penelitian terdiri atas dua kelas yang memperoleh perlakuan berbeda, yaitu pembelajaran konvensional dan model Peer-Led Team Learning (PLTL). Tes kemampuan matematis digunakan sebagai instrumen penelitian dan diberikan sebelum serta sesudah perlakuan. Hasil analisis data menunjukkan adanya peningkatan signifikan pada kemampuan mahasiswa yang mengikuti pembelajaran dengan model PLTL. Dari dua kelas yang dijadikan penelitian sebagai kelas kontrol dan eksperimen, rata-rata nilai pre-test post-test meningkat di kedua kelas. Kelas eksperimen mengalami peningkatan yang lebih tinggi yakni dari 12,39 menjadi 73,33 dengan rata-rata N-Gain 0,70. Sementara kelas kontrol memperoleh rata-rata skor N-Gain 0,65. Pada hasil mean rank, kelas eksperimen memiliki rata-rata peringkat sebesar 44,64, sedangkan kelas kontrol sebesar 34,36. Temuan ini sejalan dengan hasil penelitian sebelumnya yang menunjukkan bahwa PLTL efektif dalam meningkatkan pemahaman konsep, kepercayaan diri, keterampilan komunikasi, dan kepemimpinan mahasiswa. Penelitian ini merekomendasikan penerapan model PLTL sebagai strategi inovatif dan kolaboratif dalam pembelajaran matematika di perguruan tinggi, serta membuka peluang bagi penelitian lanjutan terkait adaptasi PLTL pada mata kuliah lainnya.

Abstract

This study aims to examine the application of the mathematical concept of modulo in determining the rice planting period among the indigenous people of Kasepuhan Cisungsang. Using an ethnomathematical and qualitative approach, the study found that the community classifies dates in the Hijri calendar based on the remainder when divided by four (modulo 4). Dates with remainders of 1, 2, and 3 are considered auspicious for planting, while those with a remainder of 0 (multiples of 4) are avoided due to cultural beliefs. Although this practice is not formally recognized as mathematics, it demonstrates a mathematical reasoning embedded within local traditions. The findings emphasize that ethnomathematics serves as a bridge between formal mathematical concepts and local culture and can enhance contextual mathematics learning in schools.

Abstract

Mathematical literacy is a fundamental challenge in Indonesian education, as reflected in the PISA 2022 achievement, which placed Indonesia in 70th place out of 81 participating countries with an average mathematics score of 366, far below the OECD average of 472. Realistic Mathematics Education (RME), which is based on the view that mathematics is a human activity, is recognized as a contextual approach that has the potential to bridge this gap. However, there has been no systematic synthesis specifically examining the trends and effectiveness of RME on mathematical literacy in the 2020-2026 publication period. This study aims to map research trends and analyze the effectiveness of RME in improving students' mathematical literacy through a Systematic Literature Review (SLR) approach referring to the PRISMA 2020 protocol. Literature searches were conducted in Google Scholar and Scopus databases using the Publish or Perish tool with a combination of structured Boolean keywords. Screening and assessment of the eligibility of articles were managed through Covidence using the PICOS framework, resulting in 46 articles as the final data corpus. The study results show a significant acceleration in publication trends since 2023, with research dominated by junior high school students and quasi-experimental designs. RME has been consistently effective across all levels of education, with N-gain values ​​ranging from 0.29 to 0.80, mostly in the moderate to high category, and large effect sizes in several studies. The integration of RME with digital technology further strengthens this effectiveness. These findings provide a solid empirical foundation for the broader implementation of RME in mathematics education policy and practice, particularly within a competency-based curriculum framework.

Abstract

This study aims to examine the effectiveness of implementing a discovery learning model combined with scaffolding techniques in improving students' mathematical problem-solving competencies through a Systematic Literature Review approach. The underlying problem of this study is the low ability of students to solve mathematical problems due to the dominance of conventional learning approaches that are still teacher-centered. The Discovery Learning model provides opportunities for students to construct conceptual understanding independently, but in practice, students often require guidance. Therefore, scaffolding techniques are needed to direct the learning process to be more systematic and meaningful. This study analyzed 15 scientific articles with a publication period of 2020–2025 from Google Scholar, Publish or Perish, Sinta, and Garuda using the PRISMA-based Systematic Literature Review method. The analysis of these findings can be concluded that Discovery Learning assisted by scaffolding is proven to be effective in improving mathematical problem-solving abilities the use of this model is better than the use of conventional models. Scaffolding supports each stage of problem-solving, reduces cognitive load, and increases student motivation. The integration of Discovery Learning assisted by scaffolding, effectively develops students' mathematical problem-solving abilities
