The ability to solve problems is very important for students to engage in the process of learning mathematics. In this study, students' ability to solve mathematical problems will be studied using Polya's indicators. The purpose of this study is to characterize the ability of grade IX Junior High School students to solve mathematical problems directly. The type of research conducted here is descriptive qualitative research. The subjects used in this study were about thirty students from State Junior High School 25 Pekanbaru for the 2023/2024 academic year in Class IX.3. Data collection was carried out by giving a validated test instrument, which was then sorted based on the mathematical problem-solving ability test scores. The data analysis technique used the Miles and Huberman model, namely data reduction, data analysis, and data estimation. The results of the analysis for each indicator of mathematical problem-solving ability reached an average of 38.325% and fell into the low category because many students solved the problem of integer material not by the stages of the indicator and errors were found in students' answers. Based on these results, it can be concluded that students' mathematical problem-solving skills are classified as weak/low.

This study aims to reveal the counting patterns performed by Indramayu Traditional Market Traders in buying and selling activities. This research uses a qualitative approach with a descriptive case study design. The sampling technique used was purposive sampling by collecting data using snowball sampling. The participants involved in this study were three traders. Data analysis in this study used qualitative analysis from Milles & Huberman, which consisted of 4 stages: data collection, data reduction, data presentation, and conclusion. The results of this study indicate that Indramayu traditional market traders have used mathematical concepts such as addition, subtraction, multiplication, and division operations in buying and selling activities. Besides that, this study also found that traditional traders use backward calculations (from front to back) in buying and selling their wares. The calculation method traditional trader’s use differs from that usually taught in schools. This method has become a standard pattern to make it easier for them to count. Based on these findings it implies that there are other ways of operating information activities that can be used by schools formally. In addition, teachers must be able to provide the context in everyday life, especially in buying and selling activities in traditional markets, to students so that students get a broader understanding of solving problems in arithmetic material.

Algebra word problems inculcate in learners the skills and ability to think critically and look for answers to problems in society and the world. Using an explanatory sequential mixed design, the study investigated the errors made by pre-tertiary students in algebraic word problems in a selected school in the Asutifi North District of the Ahafo Region of Ghana. Whereas the Newman Error Analysis Model was used to find the types of errors students make when translating and solving algebraic word problems, protocols from topics relating to the study were carefully selected and used as interview guides alongside inspiration from the Newman Error Analysis Model. Quota and simple random sampling techniques were used to select ninety-eight (98) respondents. The Algebraic Word Problem Achievement Test (AWPAT) was given to the ninety-eight students who had studied several topics on word problems, followed by a structured interview to elicit more information from the respondents. The scores gained from the marked test items illustrated that students made more transformation errors, which happened indirectly from a lack of understanding of the concept. A careful analysis of the written responses of the five (5) students interviewed also revealed that, lack of comprehension directly translated into students’ inability to transform algebraic word problems into mathematics equations. In the same vein, the study showed that the main cause of students’ failure to translate and solve algebraic word problems was students’ lack of understanding of the concept of “word problem” among others. The study recommends that students be motivated by encouragement and praise to arouse their interest in translating and solving algebraic word problems.

Mathematics is essential for individuals to solve everyday life problems. However, students remain insufficiently motivated in mathematics learning, necessitating the implementation of engaging teaching approaches integrated with other disciplines, such as STEAM (Science, Technology, Engineering, Art, and Mathematics). This study investigated the effectiveness of a STEAM-based Project-Based Learning (PjBL) approach on mathematical literacy and character development among secondary school students. Utilizing a mixed-methods convergent parallel design, the research employed quantitative and qualitative techniques. The quantitative data collection used a literacy skills test to measure mathematical literacy. Meanwhile, the qualitative data collection to measure students' character utilized surveys, interviews, and observations. Quantitative data analysis was conducted using the Kruskal-Wallis test, while qualitative data analysis employed triangulation, including data reduction, data presentation, and data verification stages. The study results revealed that students' mathematical literacy significantly improved after participating in STEAM-PjBL-based learning. Additionally, STEAM-PjBL fosters the development of students' character traits, including teamwork, communication, and responsibility, highlighting its potential to support holistic educational outcomes. These findings indicate that integrating STEAM principles with PjBL enhances academic performance and cultivates critical 21st-century skills.

The main information of this research is the transformation of the correlation coefficient value for stock price into the distance. It is done to create a representation in metric space that can be used in cluster analysis on the correlation network, which is a dynamic network. The dynamic network is generated from the weighted edges in the form of distances in each period. Finding the cluster members of the network can be analyzed using a simple technique called a minimum spanning tree. The central cluster member is the vertex betweenness. Vertex betweenness represents banking companies with a high degree of proximity and correlation. It means that the banks that are members of the central cluster are banks with high investment value. Clustering based on betweenness centrality in the case study of stock price correlation becomes useful when transforming the value of the correlation coefficient to distance. The effort to build a network with the edge weight being the distance makes the minimum spanning tree a simple, valuable method for cluster analysis on bank stock prices. In particular, the benefit to investors, i.e., it can reveal which assets are closely correlated, indicating that they may respond to market events in a similar way and make decisions in stock purchases

Abstraction is essential to learning mathematics because the mathematical concepts obtained through abstraction will be more meaningful than directly receiving these concepts. This study aims to describe the pre-service teachers' abstraction in constructing relationships among quadrilaterals. This research method was explorative qualitative research with a purposive sampling technique. The subject of this research was a pre-service mathematics teacher who had taken a geometry course. The data analysis techniques used in this study were data condensation, data display, drawing and verifying conclusions. The research results showed that the participant used epistemic actions in an abstraction, such as recognising each quadrilateral type, building-with their properties, constructing relationships among them, and consolidating the abstract results made. Thus, the abstraction in constructing relationships among quadrilaterals can be observed from the epistemic actions: recognising, building-with, constructing, and consolidation, known as RBC+C.

While previous studies have extensively explored ethnomathematics, the relationship between ethnomathematics and ethnomodeling remains underexamined. This study investigates the connections between ethnomathematics and ethnomodeling and their implications for the institutionalization of mathematics in the context of traditional fish auction activities within the Fishermen's Community in Indramayu, Indonesia. Utilizing an ethnographic design, the study involved participants in various auction roles, including auctioneers, boat owners, captains, crew members, and traders. Data were collected through interviews and observations and analyzed using content analysis. The findings reveal that ethnomathematical practices are evident in sorting and grading fish, as well as in auction transactions, with connections to mathematical concepts such as set theory, basic statistics, social arithmetic, and arithmetic operations within an ethnomodeling framework. These results suggest that the integration of ethnomathematics and ethnomodeling into the school curriculum could support the institutionalization of mathematics education and provide a foundation for developing instructional materials based on these practices in the context of traditional fish auctions.
