Students often struggle to identify relevant analog problems when solving new tasks, highlighting the need for teachers to design simple analog problems that serve as scaffolding. This study aims to analyze prospective teachers’ analogical reasoning processes in simplifying complex geometry problems using the Analogical Reasoning in Mathematics (ARM) framework. This qualitative research involved 34 prospective mathematics teachers from a public university in Surabaya, Indonesia. Participants were selected through purposive sampling based on their academic performance and prior coursework in geometry and problem solving. Data were collected through task-based interviews, written work, and observations during problem-simplification activities. The collected data were analyzed thematically, guided by the components of the ARM framework. The results indicate that prospective teachers with varying ability levels employed different analogical reasoning strategies to simplify complex problems through ARM activities. High-ability prospective teachers identified a broader range of student difficulties and adapted the problems into two-step analog problems featuring variations in visual representations, number of circles, and geometric shapes. Conversely, low-ability prospective teachers focused on difficulties related to verbal representation and the need for concrete numerical information, adapting the problems into single, highly simplified analog problems with specific images and numbers. Overall, prospective teachers actively utilized analogical reasoning to design analog problems that addressed student difficulties. Differences in ability were associated with the complexity of adaptation strategies and the depth of difficulty identification, underscoring the importance of training prospective teachers to integrate both approaches to effectively support student understanding.

Math problems require students to think critically in solving a problem. Metacognition leads to the ability to think critically and think at a higher level cognitive process in learning. This study aims to describe the characteristics of metacognition in group discussions on fraction material for grade 5 elementary school students. This type of research uses qualitative descriptive research. The data collection methods used in this research are observation, interview and documentation. The characteristics of students' metacognition can be obtained through observation when students discuss working on problems. Metacognitive activities of 5th grade elementary school students are classified into 3 namely awareness, regulation and evaluation. Students' metacognitive awareness is able to understand the problem and students are able to know what the next thing will be done after understanding the problem. Regulation students are able to choose the strategy that will be used to solve the problem and students are able to apply the chosen strategy to solve the problem. Evaluation students are able to check the answers that are done correctly and are able to ensure that the answers are correct. During group discussions, students are divided into 3 roles, namely students as experts, facilitators and beginners. During group discussion activities to solve problems, not all metacognitive activities appear in each student. Facilitators can influence beginners to be active in the discussion and expert students can help group mates to rethink what they have done before.

This study systematically reviews 27 journals addressing autogenic obstacles in numeracy learning among elementary school students. Autogenic obstacles can be analyzed philosophically in terms of internal and external factors, which will inform more effective policy-making. Internal autogenic obstacles encompass math anxiety, cognitive limitations, and language comprehension, all of which significantly impact students' numeracy skills. Additionally, cognitive abilities such as number understanding, arithmetic operations, and symbolic representation are crucial to numeracy learning. External autogenic obstacles include unsupportive learning environments and limited resources, as well as theoretical teaching methods lacking contextualization and insufficient teacher competence in adopting student-centered approaches, which further impede numeracy development. This study also examines policies aimed at overcoming autogenic obstacles through teacher professional development, multisectoral collaboration, enhanced learning resources, and the implementation of periodic evaluations and constructive feedback, all of which are essential for ensuring the consistency and sustainability of numeracy improvement programs in elementary schools. This will enable readers to identify the challenges and their corresponding solutions.

Higher-order mathematical thinking encompasses both intuitive and creative cognitive processes, yet existing assessment frameworks collapse these into undifferentiated composites, limiting diagnostic precision and theoretical clarity. This study developed and validated a dual-construct assessment instrument measuring Mathematical Intuition (MI) and Creative Mathematical Reasoning (CMR) within the Number domain. Ten open-ended tasks were administered to 140 Grade 5 students selected through cluster sampling. Instrument validation involved expert review, Exploratory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA). Reliability was assessed using Cronbach's Alpha and Composite Reliability, while construct validity was evaluated through Average Variance Extracted and the Fornell–Larcker criterion. EFA identified two distinct factors explaining 71.2% of cumulative variance (CMR: 39.8%; MI: 31.4%), with factor loadings ranging from 0.68 to 0.86. CFA confirmed the two-factor model's superiority over a unidimensional alternative (ΔCFI = 0.08; ΔRMSEA = 0.03). Both constructs demonstrated strong reliability (α > 0.85; CR > 0.90), convergent validity (AVE > 0.50), and discriminant validity, with a moderate latent correlation (r = 0.62). The findings establish that MI and CMR are structurally separable yet functionally interdependent dimensions of mathematical cognition, consistent with dual-process theory. The validated instrument enables educators to diagnose reasoning difficulties at both the generative and elaborative phases, advancing both measurement precision and instructional targeting in primary mathematics education.

It is important for students to have reasoning skills in learning mathematics. This is due to the relationship between mathematics and reasoning. This research aims to determine students' reasoning abilities in solving flat shape problems in terms of learning styles and learning motivation of junior high school students. This type of research is descriptive qualitative. The subjects in this research consisted of six class VIII students selected from a junior high school in Malang City, namely one student with a visual learning style and high learning motivation; one student from a visual learning style and low learning motivation; one student from an auditory learning style and high learning motivation; one student from an auditory learning style and low learning motivation; one student from the kinesthetic learning style and high learning motivation and one student from the kinesthetic learning style and low learning motivation. Research data was taken from learning style questionnaires, learning motivation questionnaires, written tests and interviews. The data analysis techniques in this research are data reduction, data presentation, and drawing conclusions. The research results showed that students who had visual, auditory and kinesthetic learning styles with high learning motivation met all the reasoning indicators, while students who had visual, auditory and kinesthetic learning styles with low learning motivation did not meet all the reasoning indicators.

Background: Indonesia continues to face persistent challenges in students’ mathematical problem-solving and reasoning abilities, as reflected in declining international assessment results. These issues indicate a need for instructional strategies that more effectively cultivate higher-order thinking. CPS and PBL are widely used approaches, yet their combined effects with cognitive styles remain underexplored. Aim: This study aims to compare the effectiveness of Collaborative Problem Solving (CPS) and Problem-Based Learning (PBL) on problem-solving and mathematical reasoning abilities, and to examine the role of Field-Independent (FI) and Field-Dependent (FD) cognitive styles, including their interaction with instructional strategies. Method: A quasi-experimental 2×2 factorial design was implemented with 119 seventh-grade students assigned to CPS or PBL and classified into FI or FD groups using the GEFT instrument. Data on problem-solving and reasoning were collected through validated essay tests. MANOVA was used to analyze main and interaction effects. Results: CPS produced significantly higher gains than PBL in both problem-solving and reasoning. FI students outperformed FD students across both strategies. A significant interaction effect was found, showing that FI learners benefit most from CPS, whereas FD learners perform relatively better under PBL, although still below FI peers. Conclusion: CPS offers a more structured and effective pathway for developing higher-order mathematical thinking. Cognitive style strongly influences learning outcomes, highlighting the need for differentiated support. Instructional designs that integrate structured collaboration and cognitive-style profiling are recommended to optimize students’ mathematical problem-solving and reasoning abilities

Spontaneous problem posing is a basic concept of spontaneous mathematical thinking and science learning. Students generate problems without systematic encouragement and pose problems based on the student's desire to develop their skills. As a result, they can serve as important markers of constructive mathematical and science engagement, particularly affective engagement, for problem solvers and their classroom communities. We used a qualitative approach to analyze student characteristics, especially in the affective domain, when presenting random problems. We used an observational approach and experience sampling in each class to observe students' engagement in spontaneous problem posing both individually and in groups. The findings revealed that each student showed different characteristics when presenting problems suddenly (spontaneous problem posing). The submission of the first subject problem was categorized as problem-as-exercise, satisfying the characteristics of spontaneous originality, where constructive emotional experiences impressed more on the teacher, while negative emotional experiences impressed more on oneself (self), classmates, and mathematical activities. The submission of the second subject problem is classified as a problematic problem, fulfilling the characteristics of spontaneous originality. Negative emotional experiences are more visible in me (myself), while constructive emotional experiences are more visible in teachers, classmates, and math activities
