This study explores and investigates the process of students’ mathematical thinking literacy in solving mathematical problems. This qualitative descriptive research used a test sheet consisting of one item adapted from the PISA mathematical problem model and interview guidelines, as the instrument. One male and two female participants were selected based on problem-solving characteristics. After that, task-based interviews were carried out to investigate the process of students’ mathematical thinking literacy. Data analysis was initiated by reviewing, reducing, and concluding all collected data to describe students’ mathematical thinking literacy in solving mathematical problems. The findings suggest that mathematical thinking literacy is initiated by understanding the problem (understanding), presenting the problem in a simpler form (specializing) to represent ideas, and creating patterns or relationships (generalizing). Based on the relationship between the problem, the subject predicts a solution (conjecturing) or determines the solution to the problem, re-checks (justifying) the problem-solving process to find a logical final result, and communicates the reasons (convincing) to convince the truth of the results obtained. The results of this study help teachers understand the process of students’ mathematical thinking literacy in solving mathematical problems so that it can be used to determine the appropriate strategy in the learning process to improve students' mathematical problem-solving abilities

This research aimed to present a unique approach by integrating the Tordauk jerpara tel tradition of the Aru community into formal mathematics learning, describing the relationship between local cultural practices and mathematics concepts. The objectives were to identify the mathematics values contained in tradition and design a strategy for integrating the values into the elementary school curriculum to improve conceptual understanding and global mathematics literacy. A qualitative approach with an ethnomathematics design was adopted, additionally 20 third-grade elementary school students in Aru Regency were selected as participants. Data were collected through observation, role playing, interviews, and document analysis. The results showed the Tordauk jerpara tel tradition contained the concepts of addition, subtraction, multiplication, division, fractions, decimals, ratios, averages, and modulo arithmetic, which could be systematically mapped into the formal elementary school mathematics. The five-stage learning strategy, namely contextual exploration, mathematics identification, formalization, contextual reflection, and extension, can increased student engagement, abstraction ability, thinking flexibility, and internalization of social values. This research made theoretical contributions to ethnomathematics and culture-based mathematics education, while also proposing an adaptable strategy implemented in international contexts. Practical implications include the development of contextual with further research directions focused on strategy validation across cultural contexts.

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.

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
