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.

Abstract

This study aims to develop learning media in the form of an Artificial Intelligence-based maze game on geometric transformation material. The development of this learning media is motivated by the fact that mathematics learning tends to be boring, especially on geometric transformation material. This occurs because the application of monotonous learning methods, such as lecture methods, causes students to tend to be more passive and can lead to a decrease in student learning motivation. So the researcher developed a more interesting learning media in the form of an AI-based maze game to build student learning motivation. The game developed contains geometric transformation questions and presents them adaptively through AI logic. This research method uses an R&D (Research and Development) approach with the ADDIE model. The ADDIE stages are Analyze, Design, Development, Implementation, and Evaluation. The subjects of this study were ninth-grade students of SMP Yayasan Pendidikan Ghafa Medan. The results showed that this Artificial Intelligence-based maze game obtained a validity percentage of 82% with a very valid category, practicality obtained a percentage of 85.6% with a very practical category, and effectiveness obtained a percentage of 83.1% with a very effective category. The final evaluation showed that this learning tool was suitable for use, although improvements were still needed, such as adding penalties for wrong answers and enlarging the movement buttons. Overall, this AI-based maze game was deemed valid, effective, and practical as an interactive learning tool for geometric transformations.
