Abstract

This study aims to analyze the personality competence of ninth-grade teachers at SMP Negeri 23 Medan based on students' perceptions. The research employed a qualitative descriptive approach with data collected through observation and in-depth interviews involving nine purposively selected students. The findings reveal that most teachers demonstrated basic aspects of personality competence, such as punctuality and responsibility. However, several issues were identified, including emotional instability in handling classroom situations, favoritism, and the use of physical punishment as a disciplinary method. These findings indicate that teachers' personality competence still needs improvement, particularly in emotional regulation, fairness, and role modeling. The study recommends structured and continuous personality development programs for teachers to foster a positive classroom environment and support students' character development.

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.
