Metode etnografi yang digunakan dalam penelitian ini, bertujuan untuk mengeksplorasi konsep etnomatematika yang terdapat pada bangunan Gapura Pramuka. Penelitian ini fokus kepada kegiatan ekstrakurikuler Pramuka karena dianggap mampu membentuk jiwa kepemimpinan anggotanya. Gapura Pramuka memiliki bentuk-bentuk geometris yang dapat digunakan sebagai media dalam pembelajaran matematika khususnya materi geometri sehingga memberikan nuansa pembelajaran yang kontekstual dan pemahaman konsep matematika. Teknik observasi, wawancara, dan dokumentasi digunakan dalam pengumpulan data penelitian. Teknik triangulasi yang digunakan dalam keabsahan data yaitu menggunakan jenis triangulasi metode. Hasil penelitian menunjukan bahwa pada bangunan Gapura Pramuka terdapat bentuk-bentuk geometris, yaitu limas segitiga, segitiga siku-siku, belah ketupat, trapesium, persegi panjang, geometri transformasi, garis sejajar, dan berpotongan. Eksistensi media belajar dalam Gapura Pramuka memiliki keuntungan dengan memberikan perspektif nyata terkait geometri sehingga lebih mudah memahami konsep matematika yang sedang dipelajari.Kata Kunci: Etnomatematika, Gapura Pramuka, Ekstrakulikuler

The mathematics learning process will be effective if there is social and cultural interaction through dialogue, language and representation of symbolic meaning in mathematics. Therefore, integrating ethnomathematics as a cultural value is part of representing real environmental objects in mathematical concepts. The aim of this research is to explore mathematical concepts in the historical building of the Walahar Dam and the implications for mathematics learning. This type of research uses descriptive exploratory. Research data was collected through interviews, observation and documentation. Meanwhile, the data analysis carried out was analyzing flat shapes which were adapted to mathematics learning. The results of this research can be concluded that one of the cultural heritage heritage of the Netherlands is a historical building, namely the Walahar Dam which has flat shapes such as an isosceles triangle, circle, rectangle and a flat shape that is a combination of a rectangle and a semi-circle. To encourage students to actively participate in exploring sources that are relevant to the material being studied. This allows students to connect the contextual environment and their knowledge experiences when learning mathematics.

Analyzing the efficiency of using flashcard media on students' thinking skills related to the topic of polygons using the Problem-Based Learning (PBL) model in class IV SDIT Global Insan Madani. The basis of this study began with the low learning achievement of students in mathematics, especially in geometry material, due to monotonous teaching methods and minimal variation in learning media. The method applied in this study is the One Group Pretest-Posttest Design, involving 24 students as samples. The findings of the study indicate that the use of flashcard media in mathematics learning with the PBL approach can significantly improve students' cognitive abilities. Flashcards play a role in visualizing concepts and facilitating understanding of the material, while PBL increases students' active participation in solving problems. The combination of these two methods has proven effective in deepening understanding of the concept of polygons and increasing students' learning motivation. This study recommends the use of flashcard media as an innovation in teaching to improve mathematics learning outcomes at the elementary school level.

Penelitian ini bertujuan untuk mengetahui pengaruh penerapan permainan dadu terhadap kemampuan pengenalan angka pada anak usia 5–6 tahun di TKN Pembina Karawang. Penelitian ini menggunakan pendekatan kuantitatif dengan desain pre-eksperimental melalui model one group pretest-posttest. Subjek penelitian adalah anak kelompok B3 dan B4 yang berjumlah 30 anak. Penelitian dilaksanakan pada bulan November 2025 dengan pemberian perlakuan berupa permainan dadu sebanyak tiga kali pertemuan. Teknik pengumpulan data menggunakan lembar observasi dengan skala Likert dan dokumentasi. Analisis data dilakukan menggunakan uji Paired Sample t-Test. Hasil penelitian menunjukkan adanya peningkatan kemampuan pengenalan angka anak, yang ditunjukkan oleh nilai rata-rata pretest sebesar 50,47 dan nilai rata-rata posttest sebesar 86,13. Hasil uji hipotesis menunjukkan nilai t hitung sebesar 14,43 lebih besar dari t tabel sebesar 2,045 pada taraf signifikansi 5%, sehingga Ho ditolak dan Ha diterima. Dengan demikian, dapat disimpulkan bahwa penerapan permainan dadu berpengaruh secara signifikan terhadap kemampuan pengenalan angka pada anak usia 5–6 tahun di TKN Pembina Karawang. Permainan dadu dapat menjadi salah satu alternatif media pembelajaran yang efektif dan menyenangkan dalam pembelajaran pengenalan angka pada anak usia dini.

This study aims to explore ethnomathematics in the traditional game Galasin in Jakarta on mathematical concepts such as gradients, point to point distance, and vectors. This study uses an ethnographic approach to obtain a description of an in-depth analysis of a culture based on the information that has been obtained and by conducting observations and interviews in data collection. This research focuses on one of the traditional games in Jakarta, namely the Galasin game as a form of understanding ethnomathematics in mathematical concepts such as vectors, gradients, and point to point distances. This shows that the traditional game Galasin in Jakarta has a connection with mathematical concepts and forms of deepening in previous studies which have links with geometric mathematical concepts such as flat shapes. The existence of traditional game media in learning mathematics can provide benefits, namely visualizing mathematics learning in a real form so that students become more understanding and easier to understand learning the mathematical concepts being studied.

This study aims to analyze the effectiveness of implementing the Problem-Based Learning (PBL) model assisted by PAGER media (Geometric Board) in improving elementary school students’ mastery of the concepts of perimeter and area of plane figures. The research was conducted with fifth-grade students of SDN Daan Mogot 1, Tangerang City. A quantitative approach was employed using a quasi-experimental design with a one-group pretest–posttest design. The research subjects consisted of 28 students who also served as the research sample. The research instrument was a multiple-choice test that had been validated and tested for reliability, administered before and after the treatment. Data were analyzed using the Shapiro–Wilk normality test, the Wilcoxon signed-rank test, and normalized gain (N-gain) analysis. The normality test results indicated that the data were not normally distributed; therefore, the Wilcoxon test was applied. The Wilcoxon test results showed a Z value of –4.543 with a significance level of 0.000 (< 0.05), indicating a statistically significant difference between pretest and posttest scores. The N-gain value of 71.43% indicates a moderate improvement in students’ conceptual mastery. Based on these findings, it can be concluded that the implementation of the PBL model assisted by PAGER media (Geometric Board) is effective in improving students’ mastery of the concepts of perimeter and area of plane figures at the elementary school level.
