Background: Augmented Reality (AR) integrates virtual objects with the real world on smartphone screens, creating a seemingly seamless blend of both.Aim: This research aimed to explore the use of AR in teaching geometric solids to final-year elementary school students. An interactive tool, RA Solids, was employed, originating from a 2023 research experience in a 6th-grade class.Method: The study was conducted in a public school with students mostly classified as digital immigrants. The Didactic Engineering methodology was utilized for research.Result: The outcomes were positive, showing that the school environment was conducive to implementing the teaching and learning process of geometric solids using digital technology.Conclusion: The use of AR in education, specifically in teaching mathematics, demonstrates promising results in enhancing student engagement and understanding, particularly in the context of geometric solids.

Abstract This research was based on mathematics learning in schools that are too formal and theoretical, and are less varied so it affects students' interest in learning mathematics. For this reason, a connection between mathematics outside of school and school mathematics is needed. One way that can be used is to utilize the ethnomathematics approach as the beginning of formal mathematics teaching which is suitable with the students' level of development who are at a concrete operational stage. The same thing was stated that the presence of mathematics with cultural nuances would make a major contribution to school mathematics. The objectives of this research were (1) to find out mathematical activities in the form of numerating, measuring, and calculating in batik activities. (2) To find out the mathematical concepts of geometry and geometrical transformations contained in batik motifs. This research used ethnographic research with a qualitative approach. Data collection techniques used were observation, interviews, and documentation. Data analysis technique used data reduction, data presentation, drawing conclusions and verification. The results showed that (1) in the batik activity at the Gajah Mada Tulungagung batik production house there were mathematical activities in the form of counting when determining the number of tools and materials needed, measuring fabric, calculating night requirements, calculating color comparisons, calculating waterglass requirements, and when calculating water needs. Measuring activity is seen during the process of measuring fabrics and designing batik patterns. The next step of counting activity is seen during the process of cutting fabric from 60 yards into 27 pieces, calculating the plastisin required for 2 meter fabric, and when mixing several colors. (2) There is a mathematical concept of geometry in the form of points, curved lines, triangles and circles, and the concept of geometrical transformation in the form of translation Keywords: Ethnomatematics, Mathematics, Culture, Batik Abstrak Pembelajaran matematika di sekolah yang formal dan teoritis, serta kurang bervariasi akan mempengaruhi minat peserta didik dalam mempelajari matematika. Untuk itu diperlukan keterhubungan antara matematika di luar sekolah dengan matematika sekolah. Salah satu cara yang dapat digunakan adalah dengan memanfaatkan pendekatan ethnomathematika sebagai awal dari pengajaran matematika formal yang sesuai dengan tingkat perkembangan siswa yang berada pada tahapan operasional konkrit. Hal yang sama dikemukakan bahwa kehadiran matematika yang bernuansa budaya akan memberikan kontribusi yang besar terhadap matematika sekolah. Penelitian ini bertujuan (1) untuk mengetahui aktivitas matematika berupa membilang, mengukur, dan menghitung pada aktivitas membatik. (2) Untuk mengetahui konsep matematika geometri dan transformasi geometri yang terdapat pada motif batik. Penelitian ini menggunakan jenis penelitian etnografi dengan pendekatan kualitatif. Teknik pengumpulan data yang digunakan adalah observasi, wawancara, dan dokumentasi. Dalam menganalisis data menggunakakan reduksi data, penyajian data, menarik kesimpulan dan verifikasi. Hasil penelitian menunjukkan bahwa (1) dalam aktivitas membatik di rumah produksi batik Gajah Mada Tulungagung terdapat aktivitas matematika yaitu berupa membilang saat menentukan banyaknya alat dan bahan yang diperlukan, mengukur kain, menghitung kebutuhan malam, menghitung perbandingan warna, menghitung kebutuhan waterglass, dan saat menghitung kebutuhan air. Aktivitas mengukur terlihat saat proses mengukur kain dan mendesain pola batik. Selajutnya aktivitas menghitung terlihat saat proses pemotongan kain dari 60 yard menjadi 27 potong, menghitung kebutuhan malam untuk kain 2 meter, dan saat mencampur beberapa warna. (2) Terdapat konsep matematika geometri berupa titik, garis lengkung, segitiga, dan lingkaran, serta konsep transformasi geometri berupa translasi, rotasi, dan refleksi Kata Kunci: Etnomatematika, Matematika, Budaya, Batik

Higher-order thinking skills (HOTS) are essential for meeting the challenges of the 21st century. Therefore, these skills must be possessed by every individual engaged in the learning process. Students, as learners, need frequent practice to develop these skills. To facilitate this, prospective teachers should be capable of designing assessment instruments that foster higher-order thinking. However, in practice, teachers often struggle to create such instruments effectively, as it is a complex task. This study was initiated to address that challenge. It employed a research and development (R&D) approach using the 4D model: define, design, develop, and disseminate. The research subjects were 15 prospective mathematics teachers who developed HOTS-based test items, which were then tested on 79 seventh-grade students at Darul Akhwan International Junior High School. The developed items were evaluated for their validity and practicality through construct and empirical validity tests. The practicality was further assessed using reliability tests, item difficulty levels, and discrimination indices. The results showed that the instrument achieved 100% validity based on expert judgment. The reliability test yielded an rcount=0.659r_{count} = 0.659rcount=0.659, which exceeds the rtable=0.2213r_{table} = 0.2213rtable=0.2213; thus, the instrument is considered reliable. The discrimination index analysis revealed that 60% of the items were in the “fair” category, while the remaining 40% were categorized as “good.” Meanwhile, the difficulty level analysis showed that 15% of the items were “very difficult,” 65% were “difficult,” and 20% were “easy.” These results indicate that the instrument has an appropriate level of difficulty. In conclusion, the assessment instrument developed in this study is both valid and practical for evaluating students’ higher-order thinking skills.
