This study aims to describe the ethnomathematics activities carried out by corn farmers in Tegal Arum Village. The approach used is qualitative with an ethnographic method, with data collected through observations, in-depth interviews, and documentation from two farmers who are knowledgeable in traditional corn farming practices. The main focus of this study is to identify the application of basic mathematical concepts, such as counting, measuring, and calculating, in their daily farming activities. The results show that the farmers in Tegal Arum Village apply mathematics in a contextual form, derived from experiences and practices passed down through generations. For example, they calculate the seed requirements, estimate the number of laborers and planting time, and measure the harvest using local units like sacks and handfuls. These activities reflect the relevant application of ethnomathematics, which can be integrated into contextual mathematics learning in schools. The findings indicate that mathematics is not only taught in a formal setting in schools but also naturally develops in the community's daily life, especially through farming activities. Therefore, the results of this study are expected to serve as a reference in the development of a local culture-based curriculum that connects mathematics learning to real-life contexts.

Numeracy is an important skill that elementary school students must have, but in reality it is still relatively low because learning tends to be conventional and less contextual. Numeracy does not only include the ability to count, but also the ability to understand, use, and interpret numbers and data in various daily life contexts. One of the causes of low student numeracy is a learning approach that is less interesting and not related to real situations. This study aims to test the effectiveness of the contextual learning model (Contextual Teaching and Learning/CTL) in improving students' mathematical numeracy skills. The research design used was a one-group pretest-posttest experiment with 23 fifth-grade students of SDN 002 Teluk Bintan as subjects. The instrument in the form of a numeracy test was given before and after the implementation of CTL, then the data were analyzed using prerequisite tests (normality and homogeneity) followed by a paired sample t-test. The results showed a significant increase in students' numeracy skills. The average pretest score of 24.78 increased to 73.91 in the posttest with a significance value of 0.000 <0.05. This increase proves that CTL is effective in helping students master numeracy through a learning process that links mathematical concepts with real experiences. Thus, the contextual learning model can be an alternative learning strategy that is relevant for increasing elementary school students' numeracy, while emphasizing the importance of implementing a more applicable approach in mathematics learning.

The Children’s Reading and Learning Corner program is a community service activity implemented by Group 7 of the Community Service Program (KKN) from Universitas 17 Agustus 1945 Jakarta in Kalibaru Subdistrict, North Jakarta. This program was designed to address the challenge of low reading interest and the limited access to learning facilities among children in the local community. The main target of the activity was children aged 5–8 years, with the objective of increasing reading interest, strengthening basic cognitive skills, and fostering positive learning habits from an early age. The program was carried out through interactive learning methods with a thematic approach, combined with group discussions, question-and-answer sessions, shared reading, and simple practices that encouraged active participation. The learning materials covered Basic Mathematics, Indonesian Language, and General Knowledge, all adjusted to the children’s comprehension levels. In addition, a coloring competition was held to foster creativity, train fine motor skills, and create a fun and engaging learning atmosphere. Evaluation results indicated a significant improvement in children’s enthusiasm for learning, better understanding of the provided materials, and more active involvement during the sessions. The children also demonstrated increased self-confidence, particularly when asked to read aloud or answer questions in front of their peers. Furthermore, the provision of a bookshelf in the community hall became a strategic step to establish a sustainable reading space that could be used outside of program hours. Overall, the program successfully achieved its intended goals and is considered feasible to be expanded to other areas. Additional support in the form of a wider collection of books, more creative learning media, and consistent community involvement will be key factors in ensuring the sustainability and long-term impact of the program.

This study explores the alignment between science learning practices and children’s cognitive development stages based on Jean Piaget’s theory. Ten academic publications were systematically reviewed to examine how Piaget’s framework can be applied in science education. The findings highlight that integrating cognitive development theory is highly relevant for improving the quality of teaching and learning in schools. At the concrete operational stage (approximately 7–11 years), children learn best through direct experiences, manipulation of real objects, contextual media, and experiments that connect concepts with daily life. These methods help foster curiosity and reinforce conceptual understanding. As learners progress to the formal operational stage (around 11 years and above), they begin to think abstractly, reason logically, and analyze critically. At this level, student-centered approaches, inquiry-based methods, and constructivist learning become more effective in enhancing problem-solving, creativity, and higher-order thinking skills. The review also indicates that adapting instruction to developmental stages supports more meaningful and sustainable learning outcomes. In the Indonesian educational context, this approach can address challenges such as limited classroom facilities, diverse student learning styles, and a curriculum that is often overloaded. By applying Piaget’s insights, teachers can design learning strategies that bridge abstract concepts with concrete understanding, thus increasing student motivation and engagement. In conclusion, aligning science education with Piaget’s cognitive stages is an effective way to improve student performance and ensure long-term academic growth. The study provides valuable input for teachers, researchers, and policymakers in developing innovative, student-centered science and mathematics education.

Creative thinking skills are fundamental competencies to be nurtured in 21st-century learning, especially within science education. One promising approach to developing these skills is the use of an Etno-STEM integrated E-Module implemented through the Project-Based Learning (PjBL) model. The Etno-STEM integration seeks to link local wisdom and culture with the domains of science, technology, engineering, and mathematics, thereby creating meaningful, contextualized learning experiences. This study aims to investigate the impact of implementing an Etno-STEM integrated E-Module through PjBL on students’ creative thinking skills. The research employed a quasi-experimental design with two classes: an experimental group using the Etno-STEM integrated E-Module and a control group using cooperative learning strategies. Research instruments comprised both test and non-test tools. The test instrument included objective-reasoned questions aligned with four creative thinking indicators—fluency, flexibility, originality, and elaboration—while the non-test instrument involved structured observation sheets to monitor learning implementation. Data analysis demonstrated that the Etno-STEM integrated E-Module using the PjBL model significantly improved students’ creative thinking skills compared to conventional approaches. This finding highlights the potential of combining local wisdom with innovative instructional models as an effective and culturally responsive strategy for advancing science learning aligned with 21st-century educational demands.

Modern Islamic boarding schools not only focus on religious education, but are also required to improve the academic quality of students, including in mathematics subjects which are often challenging due to differences in students' learning styles, motivations, and abilities. This study aims to design and implement a Decision Support Sistem (DSS) based on the VIKOR method to analyze students' mathematical understanding and provide recommendations for more adaptive learning strategies. The study uses a descriptive quantitative approach with data obtained through documentation of students' grades, as well as interviews with mathematics teachers. The VIKOR method is used to evaluate students' understanding based on five main criteria, namely exam scores, report card scores, attendance, attitudes and behavior, and skills, through a process of normalization, weighting, calculation of S, R, and Q scores, and ranking students. The results show that there are five students with the lowest level of mathematical understanding, namely A11, A4, A17, A1, and A12, who have the lowest VIKOR index scores. This low level of understanding is influenced by factors such as learning attitudes, attendance, report card scores, and skills, so they require further attention and guidance from teachers. The application of the VIKOR method in SPK has proven effective in optimizing the analysis of students' mathematics achievements and providing recommendations for more targeted personal learning strategies, thereby helping to improve the quality of education and maximize students' academic potential.

The lack of interest of young children in learning numbers is a common challenge in kindergarten learning activities. Children tend to be passive during the mathematics learning process because the approach used is not appropriate to their age developmental characteristics, which prefer play, movement, and direct interaction with concrete media. To address this problem, the Community Service Program (KKN) at At-Tien Kindergarten, Sumber Gayam, focused on learning innovation by designing a simple media called the Mathematics Ferris Wheel. This media was designed by combining elements of play and motor activity, making it more engaging for children. The research in this community service activity used a Participatory Action Research (PAR) approach, which actively involved teachers and students in the planning, implementation, and evaluation stages. The media was implemented by children turning the Ferris wheel in turns, then calling out the number indicated along with the numbers before and after. Through this activity, children not only learned to recognize number sequences but also practiced concentration, courage, and communication skills. The implementation results showed that the use of the Mathematics Ferris Wheel was able to significantly improve the understanding of number concepts in early childhood. Furthermore, children's active involvement in learning also increased, demonstrated by their enthusiasm in participating in the game from start to finish. Teachers found this media to be highly beneficial because it is easy to use, flexible, and adaptable to teach other topics such as colors, shapes, and letters. Thus, this KKN activity demonstrates that innovative, participatory learning media can create a fun, contextual, and effective learning environment. Such efforts are a practical solution to improving the quality of learning in early childhood education

This study aims to examine the potential of the Baduy traditional house as a realistic context in mathematics learning, particularly in the material of spatial geometry. The traditional houses of the Baduy people not only function as residences, but also hold cultural values, philosophies, and architectural structures rich in geometric elements. Using a systematic literature review (SLR) approach, this study explores various scientific sources, including journal articles, proceedings, and reference books, that discuss the relationship between spatial elements and the structure of traditional Baduy buildings. This approach was chosen so that the study obtained is comprehensive, directed, and able to illustrate the real contribution of ethnomathematics in learning. The results of the review indicate that the Baduy traditional house contains various forms of spatial geometry that can be clearly recognized, including cuboids, triangular prisms, pyramids, cubes, and cylinders. These elements are reflected in building components such as roofs, walls, floors, support pillars, and traditional household furniture. The visual and functional representation of these spatial geometry has the potential to be a contextual resource that can be utilized by teachers in the mathematics learning process, particularly through the Realistic Mathematics Education (RME) approach. By linking abstract mathematical concepts to local cultural phenomena, students not only gain a better conceptual understanding but also increase their active engagement, motivation to learn, and awareness of their own cultural identity. These findings emphasize the importance of utilizing local wisdom as an ethnomathematics approach that can provide meaningful, contextual learning rooted in the realities of students' daily lives. Through the integration of culture and education, mathematics learning can be more relevant, engaging, and support the preservation of national culture.

The objectives of this Community Service Program are: (1) To introduce the concept of ethnomathematics to students and classroom teachers at UPT SDN 1 Rantepao as a contextual learning approach rooted in local culture, particularly the traditions of the Toraja ethnic group; (2) To enhance students’ understanding and interest in mathematics through the integration of mathematical elements found in Torajan cultural motifs, artifacts, and symbols, such as symmetry, geometric shapes, patterns, and measurement; and (3) To support teachers in developing innovative and meaningful mathematics instruction by connecting mathematical content to real-life contexts that are relevant to students' daily experiences. The program was implemented in five stages: preliminary observation and survey, preparation, implementation, group discussion and reflection, and the final stage—evaluation. Based on the results of the program, the introduction of ethnomathematics based on Torajan local culture successfully contributed to improving students’ mathematical understanding and reinforcing the relevance of mathematics instruction within the local cultural context. The three-day implementation of the program was met with highly positive responses from all school stakeholders, including strong student enthusiasm, active teacher participation, and noticeable changes in instructional practices. Evaluation outcomes demonstrated a significant improvement in student understanding, as reflected by an increase in the average quiz score from 55 to 83. Moreover, the program contributed to social transformation within the school environment, including the formation of culturally based student learning groups, positive shifts in student learning behaviors, the emergence of local student leadership, and increased awareness among both students and teachers of the importance of integrating local cultural values into the learning process.

This study aims to determine the effect of using educational gim-based learning media on students' math learning outcomes on the material of Linear Equation One Variable (PLSV). The background of this research is the low student learning outcomes in conventional math learning which is considered less interesting, especially in PLSV material which is abstract. This study used a quantitative approach with a quasi-experimental design and a nonequivalent control group design. The sample consisted of two classes, namely the experimental class (using educational gim media) and the control class (using conventional methods), which were taken from VII grade students of MTs Ra’iyatul Husnan, Wringin Bondowoso. The research instrument was in the form of pretest and posttest tests that had gone through validity and reliability tests. The pretest results showed that both classes had relatively balanced initial abilities. However, in the posttest, the learning outcomes of experimental class students showed a more significant increase than the control class. The data were analyzed using normality, homogeneity, and Mann-Whitney U Test hypothesis tests because the posttest data were not normally distributed. The analysis results showed a significance value of Asymp. Sig. (2-tailed) significance value of 0.000 <0.05, which means there is a significant effect of using educational gim media on student learning outcomes. This finding shows that interesting and interactive learning media such as educational gims can improve students' motivation, understanding and learning outcomes in mathematics. Therefore, the use of educational gims is recommended as an innovative alternative in learning mathematics, especially on material that is abstract and difficult for students to understand.

This study aims to describe students' critical thinking skills in solving social arithmetic problems based on the Polya stages and FRISCO indicators. The research subjects consisted of three students in grade VIII R-5 MTs Nurul Jadid who were purposively selected to represent the high, medium, and low ability categories out of a total of 21 students. The research method used was a descriptive qualitative approach with instruments in the form of two social arithmetic description questions and semi-structured interview guidelines. Data analysis was carried out by referring to the four stages of problem solving according to Polya (understanding the problem, planning the solution, executing the plan, and re-examination) as well as the six FRISCO critical thinking indicators (Focus, Reason, Inference, Situation, Clarity, Overview). The results of the study showed that students with high abilities were able to solve problems systematically through all stages of Polya and met almost all FRISCO indicators, especially in the aspects of Focus, Reason, and Clarity. Students with moderate ability show sufficient understanding but are inconsistent in planning and implementing solutions, and experience difficulties in the Reason, Situation, and Overview indicators. Students with low abilities experience obstacles from the early stages of understanding problems and do not show significant indicators of critical thinking. These findings indicate that the Polya stage and the FRISCO indicator can be used in a complementary manner to identify and analyze students' critical thinking skills in solving contextual math problems. The implication of this study is the need for a learning strategy that emphasizes strengthening the stages of problem solving and developing explicit critical thinking indicators in the mathematics learning process. This research also opens up opportunities for the development of more structured diagnostic instruments in measuring students' individual critical thinking skills.
