Abstract

This study aims to describe the learning obstacles faced by students in the operation of integers. The research method used is a qualitative method with a case study design. The data was taken from 16 students in grade 7, a junior high school in Batang Hari, Jambi. The data collection technique used was triangulation data. There are written tests, interviews with both students and the teacher, and document analysis. The data collection instrument used was a test of integer operations, interview guidelines, and documents (lesson plan and textbook). The results of the research showed that there are learning obstacles in the operations of integers, namely, ontogenic obstacles (difference in knowledge between natural number operations and integer operations), epistemological obstacles (limited understanding), and didactical obstacles (obstacles that come from the didactic system). Other researchers can create lesson plans based on the obstacles found in this research.

Abstract

The gap between the concept image and the concept definition will greatly affect a persons understanding of the concept. This study aims to reveal the gap between the concept image and the concept definition, and the causes of the emergence of the gap. The research subjects were 16 first-year mathematics students at one of the universities in Aceh, Indonesia. Data were obtained from the results of written tests and in-depth interviews. This qualitative research with a phenomenological study approach was analyzed descriptively. The results showed that the gap that occurs in the concept includes: the division of a non-zero number by zero yields infinity, the concept of dividing zero by zero is zero, the concept of dividing a number by zero is the same as the concept of the limit, e.g., , and the concept of the left-hand limit as means that the satisfied value of x is all negative numbers such that . The emergence of these concept images results from the subject's learning experience at school and a calculus course. This finding provides insights and considerations for educators to comprehensively introduce students to the concept of infinity to avoid misunderstandings in limit and next materials.

Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan Computational Thinking (CT) siswa SMP dalam menyelesaikan soal matematika pada materi deret aritmetika ditinjau dari Kemampuan Awal Matematis (KAM). Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan subjek siswa kelas VIII yang dipilih berdasarkan kategori KAM tinggi, sedang, dan rendah. Instrumen penelitian terdiri dari tes uraian dan pedoman wawancara. Hasil penelitian menunjukkan bahwa siswa dengan KAM tinggi mampu memenuhi seluruh indikator CT, yaitu decomposition, pattern recognition, abstraCTion, dan algorithm. Siswa dengan KAM sedang hanya mampu memenuhi sebagian indikator, sedangkan siswa dengan KAM rendah cenderung hanya memenuhi dua indikator awal. Temuan ini diperkuat oleh hasil wawancara yang menunjukkan bahwa siswa dengan KAM rendah mengalami kesulitan dalam menyusun strategi penyelesaian yang sistematis. Penelitian ini menyimpulkan bahwa KAM berperan penting dalam mendukung kemampuan CT siswa, sehingga diperlukan pendekatan pembelajaran yang adaptif dan kontekstual.   This study aims to analyze the Computational Thinking (CT) skills of junior high school students in solving arithmetic sequence problems based on their prior mathematical ability (KAM). A descriptive qualitative approach was employed, involving grade VIII students categorized into high, medium, and low KAM levels. Research instruments included problem-solving tests and interview guidelines. The findings indicate that students with high KAM were able to meet all CT indicators: decomposition, pattern recognition, abstraction, and algorithm. Students with medium KAM demonstrated partial mastery, while those with low KAM mostly fulfilled only the first two indicators. Interview results confirmed that low-KAM students had difficulty constructing systematic problem-solving strategies. The study concludes that prior mathematical ability plays a significant role in supporting students' CT skills, thus emphasizing the need for adaptive and contextual learning approaches.

Abstract

Pemecahan masalah geometri menuntut integrasi antara kemampuan kognitif dan aspek afektif, khususnya efikasi diri. Penelitian ini bertujuan mengidentifikasi profil efikasi diri mahasiswa pendidikan matematika serta menganalisis pengaruhnya terhadap proses pemecahan masalah geometri berdasarkan tahapan Polya. Menggunakan desain studi kasus kualitatif, penelitian ini melibatkan 33 mahasiswa. Data dikumpulkan melalui skala efikasi diri, tes geometri berbasis empat tahap Polya, dan wawancara semi-terstruktur dengan subjek yang merepresentasikan tingkat efikasi diri tinggi, sedang, dan rendah. Hasil penelitian mengungkap tiga profil berbeda: mahasiswa dengan efikasi diri tinggi mampu menunjukkan pemahaman mendalam hingga evaluasi reflektif; mahasiswa dengan efikasi diri sedang mampu melaksanakan prosedur namun tidak stabil pada tahap perencanaan dan evaluasi; sedangkan mahasiswa dengan efikasi diri rendah kesulitan dalam merumuskan strategi dan verifikasi hasil. Temuan ini menegaskan bahwa efikasi diri berpengaruh signifikan terhadap kualitas pemecahan masalah geometri, sehingga perlu diintegrasikan dalam perancangan pembelajaran matematika yang komprehensif. Geometric problem-solving demands the integration of cognitive abilities and affective readiness, notably self-efficacy. This study aims to identify the self-efficacy profiles of mathematics education students and analyze their influence on the geometric problem-solving process based on Polya’s stages. Employing a qualitative case study design, the research involved 33 students. Data were collected through a self-efficacy scale, geometric problem-solving tests structured according to Polya’s four stages, and semi-structured interviews with subjects representing high, moderate, and low self-efficacy levels. The findings reveal three distinct profiles: students with high self-efficacy demonstrate deep understanding followed by reflective evaluation; those with moderate self-efficacy execute procedures correctly but show instability during the planning and evaluation stages; while students with low self-efficacy struggle with strategy formulation and result verification. These findings underscore that self-efficacy significantly influences the quality of geometric problem-solving, highlighting the necessity of integrating affective factors into the design of comprehensive mathematics instruction.

Abstract

Spatial ability is a crucial aspect that supports students in visualizing and understanding abstract mathematical concepts, particularly flat-sided geometric shapes in geometry learning. This study aims to identify the factors that differentiate students with low and high spatial abilities through discriminant analysis. The factors analyzed include Mental Rotation, Spatial Orientation, Visualization, Spatial Relation, and Spatial Perception, measured using a spatial ability test. The test instrument consisted of five questions developed based on the spatial ability framework offered by Maier and validated by mathematics and learning evaluation experts. A total of 34 ninth-grade students from a junior high school in Tangerang Regency were selected through purposive sampling. The analysis results showed that Visualization, Spatial Relation, and Spatial Perception were the main predictors that significantly differentiated the two groups. Visualization supports the ability to imagine geometric objects, Spatial Relation facilitates the understanding of relationships between objects, and Spatial Perception aids in recognizing the position and relationship of geometric elements. The resulting discriminant model had an eigenvalue of 13.967, indicating a strong discriminant power in separating student groups. Understanding these differentiating factors provides a foundation for designing effective learning strategies, such as the use of augmented reality (AR) applications and 3D modeling tools to enhance students’ comprehension of spatial figures. Furthermore, interventions using physical or virtual manipulatives can be tailored to students’ needs, assisting them in mastering the concept of flat-sided geometric shapes.

Abstract

Diabetes melitus (DM) merupakan gangguan metabolisme yang ditandai dengan peningkatan kadar glukosa darah (hiperglikemia). Jumlah penderita DM terus meningkat secara global, dan Indonesia menempati peringkat keempat negara dengan jumlah kasus terbanyak di dunia. Penelitian ini membangun model matematika Susceptible--Exposed--Infected--Treated--Recovered (SEITR) untuk menggambarkan dinamika perkembangan jumlah penderita DM dengan melibatkan faktor risiko biologis seperti genetik dan non-genetik, serta pengaruh pola hidup dan perawatan. Hasil analisis menunjukkan bahwa terdapat dua titik ekuilibrium, yaitu ekuilibrium bebas penyakit dan endemik yang bersifat stabil jika transisi individu sehat menjadi pradiabetes akibat faktor genetik, non-genetik, pola hidup buruk, dan laju kelahiran tidak lebih besar dibanding gabungan laju kehilangan dari status karena kematian alami, perkembangan ke DM, atau pengendalian.  Solusi numerik bersesuaian dengan analisa kualitatif dan menggunakan metode Runge-Kutta Fehlberg. Hasil simulasi menunjukkan bahwa pengendalian perkembangan DM dapat dilakukan melalui dua hal, yaitu meningkatkan laju pola hidup sehat dan meningkatkan pencegahan sejak fase pradiabetes.

Abstract

Abstract Abstract algebra plays a crucial role in undergraduate mathematics education by fostering axiomatic reasoning, structural thinking, and formal proof construction. Comprehensive mappings of the field remain limited. This study aims to identify global research trends in abstract algebra learning through a bibliometric analysis of 75 Scopus-indexed publications published between 1973 and 2025. Using Biblioshiny in R, the analysis examined publication growth, influential sources, authorship patterns, geographical distribution, citation impact, and thematic structures. The results indicate a substantial increase in research activity, particularly after 2010, with strong contributions from mathematics education journals and research communities in the United States and Europe. Thematic analysis reveals that group theory, instructional approaches, and mathematics education are the dominant topics, whereas issues related to epistemological transitions and learning obstacles remain underexplored. These findings provide an overview of the development of abstract algebra learning research and highlight opportunities for future design-based studies aimed at addressing learning obstacles in advanced mathematics education. Abstrak Aljabar abstrak merupakan mata kuliah penting dalam pendidikan matematika karena mengembangkan penalaran aksiomatis, pemikiran struktural, dan kemampuan pembuktian formal. Kajian yang memetakan perkembangan bidang ini secara komprehensif masih terbatas. Penelitian ini bertujuan menganalisis tren penelitian global tentang pembelajaran aljabar abstrak melalui studi bibliometrik terhadap 75 publikasi terindeks Scopus periode 1973–2025. Analisis dilakukan menggunakan Biblioshiny pada perangkat lunak R untuk mengkaji pertumbuhan publikasi, sumber yang berpengaruh, pola kepenulisan, distribusi geografis, dampak sitasi, dan struktur tematik penelitian. Hasil menunjukkan peningkatan publikasi yang signifikan, terutama setelah 2010, dengan kontribusi dominan dari jurnal pendidikan matematika serta peneliti di Amerika Serikat dan Eropa. Analisis tematik mengungkap dominasi topik teori grup, pendekatan pembelajaran, dan pendidikan matematika, sementara isu transisi epistemologis dan learning obstacles masih relatif kurang diteliti. Temuan ini memberikan gambaran perkembangan bidang serta mengidentifikasi peluang penelitian lanjutan untuk mengatasi hambatan belajar pada pembelajaran matematika tingkat lanjut.
