This study aims to identify and analyze the epistemological obstacles encountered by junior high school students when solving PISA-based mathematical literacy problems on the topic of System of Linear Equations in Two Variables (SLETV), viewed from the perspective of PISA competency levels. The research seeks to contribute to the development of more effective mathematics instruction. This study is deemed essential because epistemological obstacles can hinder students' ability to apply mathematical concepts in real-world contexts an ability that is central to international assessments such as PISA. A qualitative approach was employed through Didactical Design Research (DDR), involving 23 ninth-grade students. Data were collected through a written test consisting of a mathematical literacy problem adapted from PISA items, and supported by interviews and classroom observations. The data were analyzed using qualitative descriptive methods, focusing on students’ thinking processes and emerging error patterns. The findings reveal that students encounter various epistemological obstacles across all PISA competency levels (1b to 6), such as conceptual misconceptions, procedural errors, and difficulties in translating contextual information. At the lower levels (1b–3), students struggled to formulate basic algebraic models and perform arithmetic operations. At the higher levels (4–6), they experienced challenges in handling complex calculations, verifying solutions, and applying reasoning in abstract or multi-step situations. These obstacles stem from fragmented prior knowledge, limited exposure to contextual problems, and a lack of reflective habits. This study highlights the importance of integrating authentic real-world problems, providing systematic scaffolding, and fostering continuous self-verification practices in instructional design. The findings offer practical insights for developing targeted pedagogical interventions to enhance students' mathematical literacy and better prepare them to tackle SLETV problems in contexts similar to those featured in PISA.

Perlu dikembangkan model pembelajaran matematika di pesantren yang dikaitkan dengan permasalahan yang sesuai dengan situasi di pondok pesantren, misalnya terkait dengan fiqh. Penelitian ini menggunakan Design Didactical Research (DDR). Pengembangan desain didaktis ini dilakukan dengan menggunakan Theory of Didactical Situation (TDS). Pembelajaran matematika di pesantren dirancang sebagai berikut: pembacaan ayat suci Al-Qur'an dan Hadits terkait materi pembelajaran matematika; materi dan tujuan pembelajaran yang terkait dengan ilmu keislaman; dan memberikan gambaran tentang manfaat mempelajari materi yang akan dipelajari dalam kehidupan sehari-hari, terutama ketika nantinya menjadi kader ulama. Pengembangan desain didaktis didasarkan pada teori situasi didaktis, yaitu: Situasi Devolusi, santri diberikan tantangan untuk menyelesaikan masalah zakat dan waris; Situasi Matematis, santri yang belum mampu menyelesaikan tantangan utama dibimbing melalui soal, tabel, dan petunjuk. Demikian pula santri yang sudah memiliki tebakan pemecahan masalah terus melakukan langkah-langkah untuk menguji keabsahan asumsi tersebut dengan menjawab beberapa pertanyaan, memperhatikan tabel, dan melaksanakan instruksi; Situasi Kelembagaan, santri membuat kesimpulan dengan bimbingan guru tentang poin-poin penting. It is necessary to develop a mathematics learning model in pesantren that is associated with problems that are following the situation in the Islamic boarding school, for example, related to fiqh. This study used Design Didactical Research (DDR). The development of this didactic design was carried out using the Theory of Didactical Situation (TDS). The learning mathematics in pesantren is designed as follows: reading of the holy verses of Al-Qur'an and Hadith related to mathematics learning materials; the material and learning objectives associated with Islamic knowledge; and giving an overview of the benefits of studying the material to be studied in everyday life, especially when later becoming a cadre of the ulama. Didactic design development is based on the theory of didactic situation, namely: In the case of Devolution, santri are given the challenge of solving zakat and inheritance problems; in Mathematical Situations, santri who have not been able to complete the main difficulties are guided through questions, tables, and instructions. Likewise, santri, who already has problem-solving guesses, continues to test the validity of these assumptions by answering several questions, paying attention to tables, and carrying out instructions; 3) Situation of Institutionalization, santri makes conclusions with teacher guidance about essential points.

Penting bagi siswa untuk menguasai literasi matematis yang mencakup kemampuan merumuskan, menerapkan, dan menafsirkan dalam menyelesaikan masalah. Namun, siswa masih menghadapi kesulitan dalam proses literasi matematis, khususnya pada materi rasio dan proporsi, yang dapat dikategorikan sebagai hambatan belajar atau learning obstacles. Penelitian ini bertujuan untuk mengidentifikasi hambatan belajar siswa dari tiga aspek, yaitu epistemologis, didaktis, dan ontogenik dalam konteks literasi matematis pada materi rasio dan proporsi. Penelitian ini menggunakan pendekatan kualitatif dengan metode fenomenologi, melibatkan 78 siswa kelas VIII di Palembang, Sumatera Selatan. Teknik pengumpulan data yang digunakan meliputi tes dan wawancara, sementara analisis data dilakukan secara kualitatif melalui teknik triangulasi untuk meningkatkan kredibilitas temuan. Hasil penelitian menunjukkan bahwa siswa mengalami ketiga jenis hambatan belajar dalam proses literasi matematis. Hambatan epistemologis terlihat dari keterbatasan pemahaman konsep dasar rasio, hambatan didaktis muncul akibat metode pengajaran yang tidak optimal, dan hambatan ontogenik terjadi karena kesiapan kognitif siswa yang belum memadai dalam memahami rasio secara proporsional. It is essential for students to master mathematical literacy, which includes the ability to formulate, apply, and interpret when solving problems. However, students still encounter difficulties in the mathematical literacy process, especially in the topics of ratio and proportion, which can be categorized as learning obstacles. This study aims to identify students' learning obstacles from three aspects: epistemological, didactic, and ontogenic in the context of mathematical literacy on ratio and proportion material. This research uses a qualitative approach with phenomenological methods, involving 78 eighth-grade students in Palembang, South Sumatra. Data collection techniques include tests and interviews, while data analysis is conducted qualitatively through triangulation techniques to enhance the credibility of the findings. The results indicate that students experience all three types of learning obstacles in the mathematical literacy process. Epistemological obstacles arise from a limited understanding of the basic concept of ratios, didactic obstacles stem from suboptimal teaching methods, and ontogenic obstacles are due to students' cognitive readiness for understanding proportional reasoning.
