Critical thinking is a cognitive activity involving the ability to understand, analyze, evaluate, conclude, explain, and regulate thoughts systematically and objectively. This qualitative case study aims to describe students' critical thinking processes in solving contextual problems, specifically examining sensing and intuition learning styles. The research involved two 10th-grade students, one with a sensing style and one with an intuition style, selected via purposive sampling. Data collection utilized learning style questionnaires, math ability tests, contextual problem-solving tasks, and interviews. Data analysis was based on Mason et al. (2010) problem-solving stage indicators. The study found that the critical thinking processes of students with sensing and intuition learning styles are similar across the entry, attack, and review stages. In the entry stage, students gather important information, relate it to existing knowledge, and determine initial problem-solving steps. In the attack stage, they design a problem-solving strategy and execute it. In the review stage, students review solution steps, reflect on difficult parts, and explore alternative solutions.

Proportional reasoning is the basis for understanding advanced mathematical concepts, but students in Indonesia still have difficulty in solving problems involving proportions and ratios. This study aims to describe the level of students' proportional reasoning in solving missing value problems with the help of GeoGebra. The research method used was qualitative with a case study approach, involving three students in class IX at one of the public junior high schools in Surabaya. The selection of subjects was based on mathematical ability, the same gender, and good communication skills. The research instruments included the researcher, mathematics ability test, proportional reasoning test, and interview. The results showed that students with high, medium, and low mathematics ability had reached level 2 in solving missing value problems using GeoGebra. The significant difference among the three students lies in the strategy used when solving the problem. This research has implications for students' proportional reasoning using GeoGebra. However, the results of this study do not represent the overall level of proportional reasoning of junior high school students.

This study aims to identify teachers' ability to pose problems. This study uses a descriptive method with a qualitative approach. The data collection methods used are tests, semi-structured interviews, and open interviews. The research subjects were two mathematics teachers at a senior high school. The data were analyzed using the interactive analysis model of Miles, Huberman, and Saldana (2014), which consists of three stages: (1) data condensation; (2) data presentation; and (3) conclusion drawing and verification. The results showed that both subjects posed problems using the pre-solution posing type, which is posing questions based on the given situation or information, and within-solution posing, which is reformulating questions that have already been solved. Neither subject posed problems using the post-solution posing type, which involves modifying the objectives or conditions of a solved problem to create a new problem. In conclusion, teachers' problem-posing abilities showed differences, with ON tending to be limited to pre-solution posing with learning resource constraints, while IM was more varied and coherent. However, both agreed that problem posing is beneficial if supported by appropriate learning strategies and adequate learning resources to encourage student creativity and understanding.

This study aims to describe students' critical thinking skills in solving PISA-type mathematical problems related to change and relationships, from the perspective of self-efficacy. This research employed a qualitative descriptive approach with two eighth-grade students from SMP Negeri 3 Surabaya in the 2024/2025 academic year, selected based on high and low self-efficacy levels, while considering similar gender, equivalent mathematical ability, and good communication skills. Data collection techniques included a self-efficacy questionnaire, mathematics ability test, problem-solving test, and task-based interviews. Data were analyzed based on indicators of critical thinking: Focus, Reason, Inference, Situation, Clarity, and Overview. The findings indicate that students with low self-efficacy struggle to identify key information, develop logical strategies, and reflect on their approaches. In contrast, students with high self-efficacy demonstrated more systematic understanding, well-structured problem-solving techniques, and reflective, argumentative reviews. These results suggest that self-efficacy plays a significant role in influencing the quality of students' critical thinking. Therefore, teachers need to design learning strategies that enhance students' self-efficacy, such as by providing appropriate challenges, offering positive feedback, and reinforcing successes, so that mathematics instruction becomes more effective in fostering critical thinking skills.

Problem-solving ability is an important skill for students because it is the main indicator of success in learning mathematics, especially in spatial geometry material that requires conceptual understanding and appropriate strategy application. This study is a descriptive qualitative study that aims to describe students' problem-solving abilities in spatial geometry material through Collaborative Problem Solving (CPS) by comparing homogeneous and heterogeneous student groups. This study was conducted on eighth-grade students at SMP Negeri 23 Surabaya in the odd semester of the 2025/2026 academic year. The research subjects consisted of six students who were grouped into two groups, namely one homogeneous group with high mathematical abilities and one heterogeneous group consisting of students with high, medium, and low abilities. Research data were collected through mathematical ability tests, spatial geometry problem-solving ability tests carried out collaboratively, and interviews. The results showed that students' problem-solving abilities were analyzed using Polya indicators collaboratively. Homogeneous groups were able to demonstrate a more systematic and balanced problem-solving process in understanding problems, making plans, implementing plans, and evaluating solutions. The research findings indicate that group composition influences student problem-solving.

Numeracy is the ability of students to identify information, use mathematical facts and procedures, and evaluate results or mathematical ideas represented in various forms to solve problems in everyday life. Meanwhile, the Adversity Quotient (AQ) refers to a person's ability to endure and persevere through various events that cause difficulties or challenges. The aim of this study is to describe the numeracy skills of senior high school students in solving AKM (Minimum Competency Assessment) questions on number content, viewed from the perspective of Adversity Quotient (AQ). The type of research used is descriptive research with a qualitative approach. The research subjects consisted of one representative student for each AQ category, selected purposively to allow an in-depth exploration of numeracy processes. The research instruments included the ARP (Adversity Profile Response) questionnaire, AKM Number Content Questions (SAKB) (which consist of three contexts scientific, socio-cultural, and personal), and an interview guide. The analysis was based on numeracy indicators that included: identifying information and assessing the problem mathematically, using mathematical facts and procedures, and interpreting and evaluating the results. In this study, the student in the climber AQ category was able to fulfill all numeracy indicators across all question contexts. Meanwhile, the camper category student was unable to identify information and assess the problem mathematically in the scientific context. The student in the quitter AQ category met all numeracy indicators only in the personal context. These findings suggest that understanding students’ numeracy skills by considering their Adversity Quotient can help teachers plan instructional strategies that meet students’ needs. In the future, mathematics education should focus not only on improving numeracy skills but also on fostering students’ persistence and resilience in problem-solving.

This systematic literature review examines the effects of ethnomathematics-based approaches on numeracy and mathematical reasoning skills among elementary school students. The review analyzed 18 empirical studies and meta-analyses published between 2022 and 2025 to capture recent evidence aligned with contemporary educational contexts and pedagogical practices. Using PRISMA guidelines, quantitative and qualitative findings from quasi-experimental, mixed-method, and meta-analytic studies were synthesized. This review addresses a notable research gap, as recent literature has not comprehensively examined the combined impact of ethnomathematics on both numeracy and mathematical reasoning at the elementary level. The findings consistently demonstrate that ethnomathematics-based instruction significantly improves students’ numeracy achievement and mathematical reasoning abilities. Meta-analytic results indicate strong to very strong effect sizes (ES = 1.22–1.42) on mathematical achievement. Culturally contextualized learning also enhances conceptual understanding, critical thinking, collaboration skills, and learning motivation. Positive effects are reported across grade levels and cultural contexts, with moderate to high improvements in numeracy outcomes. Various implementation modalities, including interactive digital media, traditional games, STEAM-oriented instruction, and culturally relevant learning modules, show high instructional validity and effectiveness. However, several studies exhibit methodological limitations, such as small sample sizes, limited use of control groups, and insufficient longitudinal analysis. Future research should prioritize large-scale and longitudinal studies, alongside systematic teacher professional development, to support the sustainable integration of ethnomathematics in elementary mathematics education.

Geometry is one of the important components in mathematics learning at the elementary school level in the implementation of the independent curriculum. One of the fundamental elements taught is the measurement of the area of flat shapes. The main objective of geometry learning is to help students understand the characteristics of various geometric shapes, so they can develop critical thinking skills and apply them in solving problems related to everyday life. This research focuses on analyzing the learning difficulties of fifth-grade students at SD Negeri Gerbo V, Pasuruan Regency, in understanding and calculating the area of flat shapes. The objective of this research is to identify the difficulties faced by students and to find solutions that can be implemented by teachers to overcome these difficulties. This research uses a qualitative method with an exploratory study approach through the administration of descriptive tests to 22 students. From the identification results, 20 students experienced difficulties in solving the area of flat shapes. The difficulties include a lack of understanding of flat shape formulas, errors in applying the formulas, and mistakes in applying relevant data. This is influenced by low learning motivation, as well as weak mastery of basic arithmetic operations such as multiplication and division. To address these issues, the teacher undertakes various efforts such as providing relevant concrete examples, actively motivating students, and repeatedly delivering the material and practice questions to strengthen students' understanding.

Objective: The study aims to identify mathematics anxiety profiles among junior high school students and examine the dominant psychological predictors influencing students’ mathematical problem-solving ability. The study addresses the limitation of previous research that often treats mathematics anxiety as a single emotional barrier by examining variations in students’ anxiety characteristics and their associated predictors. Method: A mixed-methods sequential explanatory design was employed involving 183 seventh-grade students from two public junior high schools in West Surabaya, Indonesia. Quantitative data were collected using a mathematics anxiety questionnaire and a mathematical problem-solving ability test. Descriptive statistics and multiple regression analysis were conducted to identify anxiety profiles and determine dominant predictors within each profile. Qualitative data from interviews were analyzed to provide deeper explanations of quantitative findings. Results: The findings revealed that students demonstrated different mathematics anxiety characteristics associated with variations in problem-solving ability. Regression analysis showed that dominant predictors differed across anxiety profiles. Psychological factors emerged as the strongest predictor in Cluster 1 (B = 1.692, p < 0.001), while personality factors became the dominant predictor in Cluster 2 (B = 1.899, p = 0.021). Novelty: The study contributes to mathematics education research by demonstrating that mathematics anxiety should not be viewed as a homogeneous construct. Instead, different anxiety profiles are associated with different dominant predictors, providing implications for developing differentiated learning strategies that support inclusive and quality mathematics education aligned with Sustainable Development Goal 4.

Indonesian Migrant Workers (PMI) in Brunei Darussalam face limited access to continuing education, lack of entrepreneurial skills, and insufficient understanding of the integration between education, ecology, and business. To address this gap, the FMIPA team from Universitas Negeri Surabaya conducted an online EduEcopreneurship training in November 2025. The activity employed a participatory workshop approach and a pretest-posttest evaluation design. Results indicated a significant improvement in participants’ conceptual understanding, with average scores rising from 52.4 to 84.2 (a 31.8-point increase, or 60.7%). Moreover, 93.3% of participants successfully designed business ideas that integrated the three core pillars of EduEcopreneurship: Eco-Innovation, Eco-Opportunities, and Eco-Commitment. Participant feedback was rated “Good” (average 4.08 on a 5-point scale). These findings confirm that EduEcopreneurship serves as an effective dual empowerment model,combining non-formal education and sustainable economic development,for migrant workers.
