Abstract

Mathematical reasoning is an important skill for students in thinking critically and solving complex math problems, but this ability is still low, especially in algebraic operations. This study aims to describe the mathematical reasoning ability of junior high school students in solving algebraic multiplication based on personality type. This qualitative research uses a case study with 34 seventh-grade students of public junior high schools. The research instruments include the personality type scale and the mathematical reasoning test. Data analysis includes data reduction, data presentation, and conclusion drawing. The results showed 28.57% of extroverted students had high reasoning, 50% were moderate, and 21.43% were low. Meanwhile, 30% of introverted students have high reasoning, 45% moderate, and 25% low. There are differences in mathematical reasoning characteristics between extroverted and introverted students. This finding has implications for the need for adaptive learning strategies tailored to students' personality types in solving simple and complex mathematical problems.

Abstract

This study explored the differences in undergraduate students' concept images related to angles formed by a transversal intersecting any two lines compared with concept definition. Using diagnostic tests and interviews, the qualitative study with phenomenological design examined various student representations and common error patterns.  Students' answers were analyzed qualitatively to identify patterns, misconceptions, and variations in their concept images, followed by semi-structured interviews to explore their justifications. Participants were 35 second-semester students from the mathematics education study program at a state university in Aceh, Indonesia, who had completed the plane geometry course. The findings revealed significant variations in students' concept images, which were: (1) pairs of alternate interior/exterior angles, corresponding angles, and same-side interior/exterior angles were formed when two parallel lines were intersected by a transversal; (2) the measure of corresponding angles must be equal; (3) the measure of alternate interior angles must be equal; (4) the measure of alternate exterior angles must be equal; (5) the measure of same-side interior angles must be equal; and (6) misunderstanding and incorrectly identifying alternate exterior angles. These results highlight the importance of adapting teaching approaches to address differences in concept images and to better support students in mastering geometric concepts.  The novelty lies in its use of the Zone of Concept Image Differences to analyze the gap between students' concept images and formal definitions, offering insights into how to bridge these gaps in teaching.

Abstract

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.

Abstract

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.

Uji coba dengan 33 mahasiswa diperoleh rata-rata hasil tes kemampuan penalaran 61.21, dengan interval antara 56.59 - 65.84, mengindikasikan peningkatan keterampilan penalaran. Penelitian ini menekankan pentingnya integrasi teknologi komputer dalam pembelajaran, yang dapat meningkatkan pengalaman belajar dan kinerja akademis mahasiswa dalam matematika. One of the challenges faced by students is the limited access to computer laboratory facilities, which hampers mathematics learning, particularly in numerical methods. This limitation impedes the development of critical mathematical thinking skills essential for understanding algorithms and constructing numerical solution programs, highlighting the need to prioritize the development of these skills. Direct instruction is less effective, necessitating an enhancement through the use of interactive digital media, specifically computer-assisted instruction, known as Direct Instruction-Computer Assisted (DI-CA). This research employs a research and development (RnD) approach to create and validate digital instructional media to improve students' mathematical reasoning. The research subjects are mathematics education students, and data are obtained from expert validation, user experience, and mathematical reasoning ability tests through pre-tests and post-tests. The web-based instructional media used in DI-CA was validated based on clarity of instructions, content appropriateness, and user experience, all of which were confirmed to be valid. The trial involving 33 students yielded an average mathematical reasoning test score of 61.21, ranging between 56.59 and 65.84, indicating an improvement in reasoning skills. This study underscores the importance of integrating computer technology into instruction, which can enhance learning experiences and academic performance in mathematics.
