Abstract

Pèsapèyan ling-giling was one of the iconic local wisdom of Madura. This game was a miniature version of the bull race. In this game, wheels replaced the bull as the driving force. As a result, this game was suitable for players of all ages. This research aimed to explore mathematical concepts in the pèsapèyan ling-giling game. This research used a qualitative approach with an ethnographic research type. Researchers used taxonomic analysis to examine the internal structure of mathematical concepts within the stages of the pèsapèyan ling-giling game. The study showed that the pèsapèyan ling-giling game contained mathematical concepts in the stage of tool-making, game rules, gameplay, and playing field. The mathematical concepts found in pèsapèyan ling-giling were numbers (e.g. the concepts of order, ranking, estimation, and optimization), measurement (e.g. the concept of length, area, speed, and distance, geometry (e.g. the concepts of lines, rectangles, circles, blocks, symmetry, coordinates, and position), discrete mathematics (e.g. the concept of graphs, relations and functions, and combinatorics) proportion, and probability. Thus, the traditional game of pèsapèyan ling-giling could be a learning medium for these mathematical concepts at elementary and secondary schools.

Abstract

This study lies in the need to bridge school mathematics with local cultural heritage by emphasizing the relevance of the ethnomathematics framework in promoting contextual learning. Traditional musical instruments, such as Gendrang (Bugisnese drums) and Pui-pui (Bugisnese flutes), serve as cultural artifacts that can be explored through the lens of three-dimensional geometry. However, the integration of these cultural elements into mathematics education remains underexplored. This research aims to identify and model geometric concepts embedded in the two Bugisnese traditional musical instruments using GeoGebra as a visualization tool. Employing a qualitative ethnographic approach, data were collected through observation, interviews, and documentation. The analysis involved identifying geometric shapes in the instruments and constructing mathematical models in GeoGebra. Findings reveal that Gendrang corresponds to a cylindrical shape, while Pui-pui resembles a conical shape. The volumes of both instruments were calculated using the concept of solids of revolution, and visualized interactively. The study concludes that the exploration of ethnomathematics through Bugisnese traditional musical instruments, supported by dynamic visualization in GeoGebra, enhances students’ understanding of three-dimensional geometry, fosters cultural appreciation, and reinforces the contextual relevance of mathematics in local traditions.

Abstract

Misconceptions in integer operations remain a common challenge among junior high school students, affecting their understanding of mathematical concepts and procedures. This study aimed to remediate these misconceptions through a role-playing approach that integrates physical and contextual learning experiences. The participants were five seventh-grade students from a junior high school in West Kalimantan, Indonesia, selected based on diagnostic test results and teacher recommendations. A descriptive qualitative design was employed, with data collected through tests, observations, interviews, and documentation. The remediation process was carried out in four systematic stages involving role simulation with physical number lines, group discussions, contextual problem-solving, and reflection. The findings revealed that students successfully overcame conceptual, procedural, and operational misconceptions, while representational misconceptions decreased considerably though still persisted in some students. Role-playing proved effective in fostering engagement and conceptual reconstruction, indicating its potential as an alternative strategy for misconception remediation. Further enhancement of visualization tools, such as number line media or digital supports, is recommended to optimize learning outcomes.

Abstract

Algebra is a fundamental component of mathematics education that supports students’ success in higher-level mathematical learning. However, many students struggle to understand algebraic concepts due to their abstract nature and the limited use of effective instructional strategies. This scoping review aims to (1) identify how algebra teaching activities are represented in the literature, (2) explore the main instructional themes and approaches discussed, and (3) examine existing research gaps that require further study. A total of 143 studies published between 2015 and 2025 were retrieved from the Scopus database, and after a rigorous screening process, six studies met the inclusion criteria for full analysis. The review identified five dominant instructional themes: contextual problem-based learning, visual and concrete representations, technology-enhanced and game-based learning, collaborative discussions, and reflective reasoning. These approaches were found to enhance students’ engagement, conceptual understanding, and algebraic reasoning. Nevertheless, significant gaps remain in early algebra instruction, teacher professional development, and the integration of emerging technologies in classroom practice. The findings underscore the need for innovative, inclusive, and technology-integrated teaching strategies to strengthen students’ algebraic thinking and improve the quality of mathematics education.

Abstract

Mathematics anxiety is a pervasive issue among adolescents, often impairing academic performance and emotional well-being. This study investigates the psychological profile of an Indonesian high school student experiencing mathematics anxiety following an academic transition from the UK to Indonesia and evaluates the effectiveness of a Cognitive Behavioral Therapy (CBT) intervention in reducing her anxiety. This research used a single-case qualitative design; data were gathered through psychological assessments (IST, DAT A5, SSCT, graphic tests), structured interviews with the participant, parents, and teachers, and behavioral observations. A five-session CBT intervention focusing on cognitive restructuring was conducted over two weeks. The assessment revealed average intellectual ability but significant cognitive distortions, physiological symptoms, and avoidance behaviors related to mathematics. Post-intervention findings demonstrated notable improvements in cognitive beliefs, emotional regulation, class participation, and help-seeking behavior. The participant, her teacher, and her mother all reported reduced anxiety and improved academic coping. The findings support the use of CBT as an effective and culturally adaptable approach for addressing mathematics anxiety in adolescents. The study emphasizes the role of cognitive patterns, emotional processes, and environmental influences in the development and resolution of academic anxiety. These insights are relevant for educators, school psychologists, and mental health professionals working in diverse educational settings. However, due to its single-case design and reliance on self-reported outcomes, the generalizability of the findings is limited and further research with larger and more diverse samples is recommended.
