Abstract

This study aims to explore the integration of the Batak Toba traditional house as a contextual medium in teaching three-dimensional geometric concepts to twelfth-grade students at SMA Negeri 1 Girsang Sipangan Bolon. A qualitative approach was employed to observe how geometric shapes within the architectural structure of the traditional house—such as prisms, pyramids, and rectangular blocks—can be identified and utilized to enhance students’ understanding of spatial geometry. The results indicate that this culturally based learning approach significantly improves students’ conceptual comprehension, creativity, and learning motivation. Students find it easier to associate geometric forms with real-world structures, positively impacting their academic performance. Moreover, this method reinforces local cultural values and promotes active student engagement in the learning process. Teachers play a crucial role in facilitating the connection between mathematical concepts and cultural context. The study recommends further development of local-culture-based instructional media and teacher training to integrate indigenous knowledge into classroom learning. The integration of cultural elements in mathematics education has proven effective in creating meaningful learning experiences and fostering students' cultural identity.

Abstract

This study aims to explore the relationship between the traditional pengeret-ret ornament and the concept of plane figures from an ethnomathematical perspective. The pengeret-ret ornament, a distinctive motif from the cultural heritage of the Indonesian archipelago, was chosen as the object of study due to its rich visual patterns filled with geometric shapes. This research employs a literature study method with a qualitative-descriptive approach. Data sources include scholarly journals, ethnographic articles, and visual references of relevant traditional motifs. The findings indicate that the pengeret-ret ornament contains elements of plane figures such as triangles, squares, parallelograms, rhombuses, and circles. These patterns are arranged symmetrically and repetitively, reflecting geometric concepts such as translation, reflection, and rotation. In addition to their aesthetic and symbolic value, these ornaments also hold great potential as contextual, culturally based media for teaching geometry. Therefore, this research contributes to the development of ethnomathematics teaching materials as well as the preservation of culture through innovative approaches in mathematics education.

Abstract

This study aims to explore the relationship between the traditional musical instrument Faritia from Nias and the concept of the circle in terms of its visual form, rhythmic structure, and social symbolic meaning. Faritia is a metal idiophone shaped like a circle, commonly used in traditional ceremonies such as Mamozi Aramba. The research approach is a literature review, collecting and analyzing various sources on organology theory, Euclidean rhythm, and ethnomusicological studies. The findings indicate that the physical form of Faritia reflects principles of acoustic resonance and symbolic values commonly found in traditional cultures: balance, wholeness, and continuity. The rhythmic patterns produced by Faritia show a tendency towards cyclical beat distribution similar to the concept of Euclidean rhythms. Moreover, in social practice, Faritia is played within circular formations that reinforce collective meaning and community unity. Thus, Faritia functions not only as a traditional musical instrument but also as a multidimensional cultural symbol representing the circle in the physical, musical, and social structures of Nias society.

Abstract

This study aims to examine the effect of the Problem-Based Learning (PBL) model supported by question card media on students' mathematics learning outcomes. The research employed a quasi-experimental design involving fourth-grade students at SD Negeri Margajaya 4, with a total sample of 48 students selected through purposive sampling. Data on students' learning outcomes were collected using pre-tests and post-tests. To analyze the data, several statistical tests were conducted, including the N-Gain test, normality test, and homogeneity test as prerequisites before performing the hypothesis test (t-test). The average N-Gain score in the experimental class was 70, while the control class scored 59. Hypothesis testing using the t-test showed that the calculated tvalue (3.32929) exceeded the critical tvalue (2.01290) at a 5% significance level. This result indicates that the null hypothesis (H0) is rejected and the alternative hypothesis (Ha) is accepted. Based on these findings, it can be concluded that the implementation of the Problem-Based Learning model assisted by question card media has a significant positive effect on students’ mathematics learning outcomes. The integration of interactive media within a student-centered learning model enhances engagement and improves academic achievement in mathematics.

Abstract

The advancement of digital technology has positioned mathematical concepts as fundamental components in the operation of various digital platforms, including search engines, social media, and e-commerce systems. This study aims to investigate the extent to which university students comprehend and recognize the integration of mathematicsparticularly logic, algorithms, and statistics within the digital tools they engage with daily. Employing a descriptive quantitative method, data were collected through an online questionnaire involving 66 students from multiple academic disciplines. The results indicate that while most participants acknowledge the presence of mathematical elements in digital systems, their understanding of the underlying processes remains limited. The primary barriers identified include insufficient mastery of foundational mathematical concepts and the lack of instructional approaches that explicitly connect mathematics to digital technologies. Nevertheless, a substantial proportion of students express strong interest in learning mathematics in more practical and technology-oriented contexts. These findings underscore the need for pedagogical strategies that contextualize mathematical theory within real-world digital environments, thereby enhancing students’ digital numeracy and analytical capabilities.

Abstract

This study aims to investigate the difficulties experienced by students in understanding matrix material, with a particular focus on matrix multiplication. The research was conducted with 13 students from grade XI of Al Maksum Private High School Medan. To obtain comprehensive data, researchers used a combination of interviews and written tests. These instruments were designed to explore students’ conceptual understanding as well as the procedural aspects of solving matrix problems. The data collected were then analyzed using the Miles and Huberman model, which involves three key steps: data reduction, data display, and drawing conclusions. The results of the analysis revealed that students encountered various obstacles in learning matrices, especially in performing matrix multiplication. The main difficulties stemmed from several factors, including a lack of understanding of the basic concepts and rules that govern matrix operations, particularly multiplication. Additionally, many students made calculation errors, especially when dealing with positive and negative numbers. Some students also demonstrated low confidence in their answers, which may have led them to second-guess correct solutions. Moreover, insufficient attention to detail when performing step-by-step calculations often resulted in inaccurate final answers. These findings highlight the importance of reinforcing conceptual understanding, improving arithmetic accuracy, and building students’ confidence through targeted instructional strategies and practice. Such improvements may help students overcome their current learning obstacles in matrix-related topics.
