Pemahaman konsep pecahan merupakan kompetensi dasar penting dalam pembelajaran matematika sekolah dasar, namun pada praktiknya masih banyak peserta didik yang mengalami kesulitan dalam memahami konsep tersebut. Salah satu penyebabnya adalah penggunaan metode pembelajaran yang kurang melibatkan peserta didik secara aktif dan konkret. Penelitian ini bertujuan untuk mengetahui efektivitas metode bermain kartu bilangan pecahan terhadap pemahaman konsep pecahan peserta didik kelas IV sekolah dasar. Penelitian ini menggunakan pendekatan kuantitatif dengan desain quasi experimental model one-group pretest–posttest. Subjek penelitian berjumlah 24 peserta didik kelas IV. Instrumen penelitian berupa tes pemahaman konsep pecahan dan lembar observasi aktivitas pembelajaran. Data dianalisis menggunakan uji normalitas dan uji t berpasangan (paired sample t-test). Hasil penelitian menunjukkan bahwa rata-rata nilai pemahaman konsep pecahan peserta didik meningkat dari 67,29 pada pretest menjadi 82,96 pada posttest. Hasil uji t menunjukkan nilai signifikansi sebesar 0,000 (p < 0,05), yang menandakan adanya peningkatan pemahaman konsep pecahan yang signifikan setelah penerapan metode bermain kartu bilangan pecahan. Temuan ini menunjukkan bahwa metode bermain kartu bilangan pecahan efektif digunakan sebagai alternatif strategi pembelajaran matematika untuk meningkatkan pemahaman konsep pecahan peserta didik sekolah dasar.

Purpose: This study aims to develop an open-ended diagnostic test to identify pre-service mathematics teachers’ Dominant Mathematical Representations (DMR) in Real Analysis, with a specific focus on convergent sequences. Method: A Research and Development (R&D) approach was employed using Plomp’s development model, which includes preliminary research, prototyping, and assessment phases. The diagnostic instrument was constructed based on representational theory and consisted of six open-ended tasks designed to elicit representational choice, integration, and transferability. Content validity and linguistic clarity were evaluated by two mathematics education experts and one language expert. A limited field trial involving 19 pre-service mathematics teachers was conducted to examine the instrument’s validity and practicality. Data were collected through the diagnostic test, expert validation sheets, and a student response questionnaire, and analyzed descriptively using qualitative feedback and quantitative percentage-based indicators. Findings: The results indicate that the developed diagnostic test demonstrates strong content validity, with a mean validity score of 85.4%, classified as very valid. The practicality evaluation yielded a mean score of 83.7%, indicating that the instrument is very practical in terms of clarity, format, language, and time allocation. Expert review confirmed alignment between the test items and the DMR construct, while student responses indicated feasibility and comprehensibility. Significance: This study contributes to mathematics education assessment by operationalizing Dominant Mathematical Representations as an explicitly assessable construct through open-ended diagnostic tasks, providing a foundation for representation-sensitive instruction in Real Analysis.

The realistic mathematics approach is one of the approaches to learning mathematics that was developed to bring mathematics closer to students. Real problems from everyday life are used as a starting point for learning mathematics to show that mathematics is actually close to everyday life. A main principle of Realistic Mathematics Education is that students must participate actively in the learning process. Learners must be given the opportunity to build their own knowledge and understanding. Abstract mathematical concepts need to be transformed into things that are real for students. Realistic problems given to students do not always have to use problems that exist in the students' real world or can be found in students' daily lives. A problem is called realistic if the problem given can be imagined or real in the students' minds. Applying a realistic mathematical approach will change learning to be easy for students to understand. This approach develops children's thinking patterns by finding their own concepts in mathematics through establishing relationships between the material and children's daily lives. So that the mathematical concepts learned can be applied in life. From this, children's mathematical understanding will increase.

Mathematics learning characterized by constructivism emphasizes building one's own understanding actively, creatively and productively based on previous knowledge and experience. The teacher's task in applying constructivism to mathematics learning is not only to transmit ideas to students, but also to change the conceptions they have to develop them, therefore teachers need to pay attention to students' initial conceptions before learning begins, this aims to make it easier for students in the process. processing new knowledge that will be received. In the implementation stage of constructivist mathematics learning, teachers must understand aspects of mathematics learning that are based on constructivist theory. In this regard, a number of aspects related to mathematics learning, namely (1) students construct mathematical knowledge by integrating the ideas they have, (2) mathematics becomes more meaningful because students understand it, (3) students' strategies are better assessed, and ( 4) students have the opportunity to discuss and exchange experiences and knowledge with their friends. Based on these aspects, as much as possible, the implementation of constructivism in mathematics learning must start from basic education for children.

This study aims to analyze the effect of study habits and learning intensity on students’ mathematical problem-solving ability. The research employed a quantitative approach with an ex post facto design involving eleventh-grade students of MAN 2 Palu in the 2025/2026 academic year. The results showed that the Nagelkerke Pseudo R-Square value of 0.093 indicates that study habits and learning intensity only explain 9.3% of the variance in students’ mathematical problem-solving ability. Study habits and learning intensity have a positive and significant relationship with students’ mathematical problem-solving ability, although the strength of the relationship is relatively weak. This finding suggests that mathematical problem-solving ability is influenced by various other factors beyond the learning behaviors examined in this study. Keywords: Learning Intensity, Learning Habits, Mathematical Problem Solving Ability,

This study aims to explore the abductive reasoning strategies used by prospective mathematics teachers in proving and refuting mathematical statements. This study used a qualitative method with a case study design. Fourteen third-year prospective mathematics teachers were involved in this study and were then grouped according to the characteristics of the type of abductive reasoning they used. Data collection techniques included tests given to all prospective mathematics teachers and interviews conducted with five prospective mathematics teachers selected based on their type of abductive reasoning. The data obtained was analyzed through stages that included data condensation, data display, and conclusion drawing. Technique triangulation was used to check the validity of the research findings. In general, it was found that the types of abductive reasoning strategies used by prospective mathematics teachers in proving included fact optimization and mistaken fact. Meanwhile, in refuting mathematical statements, there are three types of abductive reasoning used by students, consisting of fact optimization, mistaken fact, and factual error. The results of this study provide insight into how abductive reasoning contributes to formulating mathematical conjectures and can help educators design relevant learning strategies to support the improvement of students' proof and refutation abilities

This study aimed to explore the characteristics of students’ mathematical problem-solving strategies in Problem-Based Learning through Polya’s stages in solving compound interest problems. This study employed a qualitative descriptive case study. The participants consisted of 35 Grade XI students at SMA Negeri 2 Tolitoli, Central Sulawesi. Data were collected through problem-solving tests, interviews, observations, and documentation. Three representative students from high-, moderate-, and low-level problem-solving characteristic profiles were selected purposively for in-depth analysis. Data were analyzed using Miles and Huberman’s interactive model. The findings showed that students demonstrated different strategy characteristics across Polya’s stages. At the understanding stage, students demonstrated complete identification, partial understanding, and misunderstanding strategies. During the planning stage, conceptual, procedural, and trial-and-error strategies emerged. At the implementation stage, students demonstrated systematic solution, procedural error, and inconsistent-step strategies, while at the reflective stage, students showed solution evaluation, partial verification, and no verification strategies. Students with high-level profiles tended to demonstrate coherent and interconnected strategy patterns, whereas students with low-level profiles demonstrated fragmented and inconsistent processes. The findings further indicated that students’ strategies developed as interconnected processes in which difficulties emerging at earlier stages influenced subsequent stages. Reflective activities were identified as the weakest component of students’ mathematical problem-solving processes. The findings contribute theoretically to understanding how students’ mathematical problem-solving strategies emerge and develop across Polya’s stages within Problem-Based Learning environments. Practically, the findings highlight the importance of strengthening reflective activities and supporting interconnected strategic thinking in mathematics learning

Mathematics learning plays an important role in developing students’ logical, critical, analytical, and systematic thinking skills. However, low interest in learning mathematics remains a common challenge that affects students’ engagement and learning outcomes. One psychological factor that may influence students’ learning interest is self-efficacy. This study aimed to explore students’ interest in learning mathematics in relation to their levels of self-efficacy. A qualitative descriptive approach was employed, involving eleventh-grade students at MAN 2 Kota Palu. A self-efficacy questionnaire was administered as a preliminary screening tool to classify students into high and low self-efficacy groups, from which four participants were purposively selected for in-depth qualitative analysis. Data were collected through semi-structured interviews, classroom observations, and documentation of students’ assignments. The findings indicated that students with high self-efficacy demonstrated greater persistence, active participation, and willingness to engage in mathematical problem-solving activities. In contrast, students with low self-efficacy tended to exhibit hesitation, reduced participation, and avoidance of tasks perceived as difficult. These results suggest that students’ interest in learning mathematics is influenced not only by cognitive ability but also by their beliefs in their own capabilities. Therefore, fostering students’ self-efficacy is essential to enhance their engagement and interest in mathematics learning.
