The surface area and volume of cubes and cuboids are mathematical concepts related to everyday life. However, many students need help learning this concept. This study aims to analyze the learning obstacles junior high school students encounter when solving mathematical representation problems on the concept of surface area and volume of cubes and cuboids. This study uses an interpretive paradigm which is part of Didactical Design Research (DDR). Students at one of the public junior high schools in Jambi City were given six questions related to mathematical representation after the researchers conducted classroom observations, which were then followed by interviews with students with high, moderate, and low representation abilities. Data analysis techniques include data reduction, display, and conclusion drawing and verification. The results showed that students experienced three learning obstacles: ontogenic, epistemological, and didactical. Furthermore, the results of this study can be a consideration for teachers to create learning designs for surface area and volume of cubes and cuboids that can anticipate student learning obstacles and develop students' mathematical representation abilities.

In this study, how the mathematical activities of fraction arithmetic within the textbooks of two neighbouring countries, Indonesia and Malaysia, are influenced by the specific conditions and constraints presented in school textbooks is reviewed and examined, and the reasons behind them are understood. Two complementary frameworks, the anthropological theory of didactics and didactical design research are used to conduct an ecological analysis contributing to the theoretical discourse and practical application. The theoretical conversation suggests that ecological differences shaping the content of textbooks from both countries exert distinct influences on specific tasks, particularly within contexts with the unique characteristics of each nation. Furthermore, the scope of additional components is also examined regarding how situational sets are presented. A reference epistemological model to frame the epistemological analysis as a basis for future didactic design is also discussed for its implications on practice.

This study aimed to analyze in depth the students' independent thinking ability in solving combination problems in combinatorics material. The research method used was a qualitative case study, involving 24 high school students in grade XI who were selected purposively based on the criteria of never having studied the concept of combination formally and never having faced similar problems. The research instrument consisted of specially designed combination story problems and semi-structured interview guidelines to explore students' cognitive processes. Analysis was carried out on four aspects of ability, namely: (1) the ability to state problems in other forms, (2) the ability to form a solution strategy, (3) the ability to apply strategies for solving, and (4) the ability to verify the results obtained. The results of the study stated: (1) problems were stated in the form of number symbols and diagrams, using narrative sentences, drawing circles, forming sets, and using symbols B1 to B6; (2) the solution strategies used included: counting with the help of symbols, counting directly without symbols, and counting alternately; (3) solutions were found by using a variable symbol and set approach; (4) no students verified their solution results. These findings confirmed that although the majority of students demonstrated independent thinking in problem-solving and strategy development, only a small proportion consistently implemented the strategy, and none verified the results. The implications of this research could serve as a reference for designing more effective learning strategies to develop students' independent thinking skills in mathematics, particularly in combinatorics.

Penelitian ini merupakan studi kualitatif yang mengeksplor kesalahan konstruksi konsep dua mahasiswa akuntansi dengan identitas matematis positif. Penelitian dilaksanakan dari bulan Desember 2023 sampai Januari 2024 pada salah satu universitas di Sulawesi Selatan. Data dikumpulkan melalui pemberian tes (soal utama dan soal pelacak yang dirancang khusus untuk mengetahui kesalahan konstruksi konsep) dan wawancara semi terstruktur. Konstruksi konsep diteliti menggunakan kerangka APOS dan mempertimbangkan beberapa kesalahan konstruksi konsep yang mungkin terjadi seperti lubang konstruksi, pseudo construction, mis-logical construction, dan mis-analogical construction. Data dianalisis dengan menggunakan tiga tahapan yaitu kondensasi data, penyajian data, dan pengambilan kesimpulan. Hasil penelitian menunjukkan bahwa bentuk kesalahan konstruksi yang dialami oleh mahasiswa dengan identitas matematis positif adalah lubang konstruksi. Dalam hal ini, mereka tidak mempertimbangkan nilai modus yang bisa lebih dari satu, dan bagaimana pengaruh outlier sehingga mereka mengalami kekeliruan dalam memilih ukuran pemusatan data mana yang paling sesuai untuk menjawab atau memecahkan masalah statistika yang diberikan.

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.
