Abstract

This research explains students' mathematical proficiency by considering mathematical resilience in solving problems. This research sample involved 30 grade 8 junior high school students in Pringgarata, who were chosen randomly. The research method used is descriptive qualitative. Data was collected through a mathematical resilience questionnaire with 12 statements, as well as a mathematical proficiency test consisting of 2 essay questions and an interview guide. The research results show that students with high mathematical resilience have good mathematical proficiency, and students in this category have a good understanding of concepts, where conceptual fluency in solving problems, choosing strategies, and adaptive reasoning are used appropriately. Students have a productive disposition, which can be seen in their being confident in their answers in solving each question. Meanwhile, moderate mathematical resilience has good mathematical proficiency, and students in this category have a good understanding of concepts, strategies, and adaptive reasoning. However, when students' conceptual fluency is in the medium category, failure to solve the problem results in a less productive disposition, productive disposition refers to self-confidence. However, students with low mathematical resilience have good mathematical proficiency, and students in this category have a good understanding of concepts and strategies. During adaptive reasoning and conceptual fluency, students in the low category failed to solve the problem, which resulted in a less productive disposition.

Abstract

The failure of students to solve matrix problems may be due to misconceptions in their concept image. Concept image encompasses cognition related to a concept, including mental representation, properties, characteristics, and cognitive processes associated with that concept. This study aims to understand students' concept image regarding matrices. The method used is qualitative with a phenomenological approach, conducted on 19 eleventh-grade students in a madrasah located in Narmada District. Data collection involves tests and interviews. Samples are selected through testing. Concept image is determined based on indicators, including aspects of mental representation, processes, and properties. The research findings reveal that Subject 1 has a strong concept image, demonstrated by their ability to relate matrix concepts to relevant contexts, internalize concepts well, and apply them in various situations. Conversely, Subject 2 has a weak concept image, struggling to form a clear mental representation of matrix concepts and facing difficulties in applying correct formulas and procedures. Therefore, it is essential to implement teaching approaches focusing on deep conceptual understanding and fostering a strong concept image to enhance student comprehension.

Abstract

In the literature, studies on technology-supported learning, especially using LMS, have been widely carried out during a pandemic. However, little is known about LMS, which is interesting and helps to develop students' statistical reasoning abilities for online learning by considering the students' Self-Regulated Learning (SRL) levels (High, medium and low). This study aims to examine and analyze the differences in statistical reasoning abilities of students who study using LMS in terms of SRL levels (high, medium and low). This study uses a quantitative method with the type of One-group pre-test post-test design. What took sampled randomly at the University of Pasundan Bandung, totalling 54 third-level students of Pasundan University Bandung, Indonesia. Research data related to statistical reasoning abilities were collected through a test consisting of six questions. In contrast, SRL level data were collected using a questionnaire consisting of 46 question items. Paired t-test and One-way ANOVA analysis were applied to answer the research hypothesis. The results of the study concluded that students studying with LMS with High SRL obtained a higher increase in statistical reasoning ability than students studying with LMS with Medium and low SRL categories, with the criteria for improvement in the three categories being in the high and medium improvement categories. Research findings related to learning using LMS can be used as an alternative learning model in online learning situations.

Abstract

Mathematical conceptual understanding is a fundamental skill that serves as a foundation for more advanced abilities, including reasoning, communication, connections, and problem-solving. However, this foundational skill is influenced by students’ prior mathematical abilities. Therefore, the objective of this study is to identify and describe differences in students’ mathematical conceptual understanding based on their prior mathematical abilities. This research employs a mixed-method approach, involving 87 purposively selected students enrolled in the Analytic Geometry in Planes and Space course. The research instruments include a mathematical conceptual understanding test and documentation of students’ prior mathematical abilities. Data were analyzed quantitatively using one-way ANOVA and qualitatively by exploring mathematical conceptual understanding across categories of prior mathematical abilities. The findings reveal that both quantitative and qualitative analyses indicate that students with high prior mathematical abilities demonstrate superior mathematical conceptual understanding compared to those with medium or low prior mathematical abilities.

Abstract

Pembelajaran matematika di lingkungan pendidikan Islam sering mengalami kesenjangan epistemologis dengan nilai-nilai keislaman, sehingga menimbulkan krisis relevansi bagi siswa. Penelitian ini bertujuan mengidentifikasi ayat-ayat Al-Qur’an yang memuat konsep bilangan, menganalisis nilai-nilai matematis yang terkandung, serta merumuskan relevansinya dalam pengembangan pembelajaran matematika berbasis nilai-nilai Islam. Menggunakan pendekatan kualitatif deskriptif dengan analisis isi terhadap teks Al-Qur’an, penelitian ini menganalisis 149 ayat dari 59 surah yang secara eksplisit menyebutkan bilangan. Data dianalisis secara tematik berdasarkan jenis bilangan, konteks ayat, dan nilai pendidikan karakter, serta divalidasi melalui triangulasi sumber dengan tafsir dan literatur relevan. Hasil penelitian menunjukkan bahwa bilangan dalam Al-Qur’an tidak hanya menyampaikan makna kuantitatif, tetapi juga merefleksikan prinsip keteraturan, keadilan, kesabaran, dan rasa syukur. Temuan ini mengungkap potensi ayat-ayat bilangan sebagai konteks pembelajaran matematika, misalnya operasi perkalian dari QS. Al-Baqarah:261 dan pecahan dari QS. An-Nisa’:11–12, yang dapat diintegrasikan melalui model Realistic Mathematics Education (RME) untuk menghubungkan konsep matematis dengan nilai spiritual. Penelitian ini memiliki keterbatasan karena belum diuji secara empiris di kelas, sehingga diperlukan studi lanjutan untuk mengukur efektivitas penerapannya. Secara praktis, hasil penelitian dapat menjadi dasar pengembangan modul ajar, soal kontekstual, dan pelatihan guru untuk pembelajaran matematika berbasis Al-Qur’an di madrasah dan sekolah Islam. Kebaruan penelitian ini terletak pada klasifikasi sistematis ayat-ayat bilangan, elaborasi nilai matematis dan karakter, serta aplikasinya dalam strategi pembelajaran, yang berfungsi sebagai jembatan antara sains dan spiritualitas dalam pendidikan matematika.
