Kairuddin — 2025-10-16

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.

ANALISIS PEMAHAMAN SISWA SMA N1 PERCUT SEI TUAN TERHADAP KONSEP DASAR BARISAN DAN DERET

Kairudin — 2025-10-17

This study aims to conduct an in-depth analysis of the level and profile of students’ understanding at SMA Negeri 1 Percut Sei Tuan regarding the fundamental concepts of Sequences and Series in mathematics learning. Conceptual understanding is a fundamental aspect of comprehensive mathematical mastery, as it not only involves the ability to apply formulas but also requires logical reasoning and comprehension of the relationships between concepts. Initial indications reveal a significant gap between students’ ability to use formulas mechanically and their deeper conceptual understanding. This research employs a Mixed Methods approach with an Exploratory Sequential design, beginning with the collection of quantitative data through written tests administered to 30 eleventh-grade science students (Class XI MIA), followed by semi-structured interviews with selected students to further explore their conceptual grasp. Quantitative analysis shows that approximately 70% of students were able to answer procedural questions—those solvable through direct formula application. However, only about 30% of students succeeded in solving more complex problems requiring deeper reasoning and conceptual understanding. The qualitative findings reinforce these results, indicating that students tend to memorize formulas without understanding their underlying meaning or origin, and often struggle to distinguish between the concepts of sequences and series. Therefore, a shift in instructional approach is needed, emphasizing exploration, conceptual discussion, and holistic understanding.

LOCAL WISDOM AS A MEANS TO FOSTER INDEPENDENCE IN MATHEMATICS LEARNING

Darmawan Harefa — 2025-10-19

Mathematics learning is often perceived by students as difficult and abstract, leading to dependence on teacher guidance and hindering the development of independent learning. This study examines the role of local wisdom as a means to build independence in mathematics learning, specifically at SMA Negeri 1 Teluk Dalam, South Nias. Through a literature review, it was found that integrating local values and culture into the mathematics learning process not only enhances conceptual understanding contextually but also motivates students to learn independently. Local wisdom, such as geometric patterns in traditional weaving, indigenous life philosophies, and traditional building structures, can serve as relevant and engaging learning media for students. This approach helps students develop critical and creative thinking skills while boosting their confidence in solving mathematical problems. Furthermore, learning based on local wisdom strengthens students’ cultural identity and fosters pride in their local heritage. This study recommends the development of learning modules that integrate local wisdom and teacher training as efforts to optimally support students’ independent learning. The implications of this review suggest that local wisdom can be an effective strategy to improve the quality of mathematics education and the development of students’ independent character within the school environment.
