<![CDATA[This study aimed to investigate the geometric patterns of medallions in Kidal Temple using a qualitative approach with an ethnographic research design. The data was collected through interviews, observation, and documentation. The research utilized both the main instrument (the researcher themselves) and auxiliary instruments including interview guidelines, observation sheets, math concept suitability sheets, and documentation tools. The geometric concept of the medallions in Kidal Temple encompassed the circle, quadrilateral, and congruence on the circle. The outer side of the medallion was a flat circular shape, which was verified through measurement and instrument adjustment. On the inside of the geometric medallion, there was a rectangular flat shape formed by four lines. Another significant finding of this study was the concept of circle equality, as the center of the medallion exhibited the same characteristics as the outer part despite differing in size. It is important to note that the scope of this research is limited to ethnomathematics studies, specifically focusing on the relief form of geometric medallions. Consequently, further research is needed to explore the implications as like as learning Realistic Mathematic Education of these findings in the context of geometric medallions.]]>

<![CDATA[Student understanding is one of the interesting topics that is often the subject of research in the scope of mathematics education. On the other hand, cognitive style has a contribution related to student understanding. This study aims to determine how the understanding of junior high school students in solving quadrilateral problems based on cognitive style field independent and field dependent. Qualitative descriptive research involving 2 students consisting of 1 student cognitive style field independent and 1 student cognitive style field dependent. Research data obtained using several instruments namely GEFT, TKM, TPM, and interview guidelines. Furthermore, data checking was carried out using time triangulation. The results showed that the understanding of students in different cognitive styles also showed different understanding when solving problems. At each stage of problem solving, including the stages of understanding the problem, developing a plan, implementing the plan, and checking back, it is described about how the understanding and the extent of the connection of information with the scheme owned by each subject. In full, the understanding of students in solving geometry problems is described comprehensively in the research results section. Students with cognitive style field independent have information linkage with schema that has much more when compared with students with cognitive style field dependent. Based on the results of the study, teachers as educators can pay more attention to students with different cognitive styles when solving math problems. Therefore, instilling understanding and training students in solving mathematical problems is something that teachers should strive for in order to achieve quality learning objectives.]]>
