THE EFFECTIVENESS OF USING ORIGAMI BOARD MEDIA IN UNDERSTANDING THE CONCEPT OF PERIMETER OF FLAT SHAPES AMONG ELEMENTARY SCHOOL STUDENTS

Abstract

This research aims to assess the effectiveness of using origami boards as a medium to enhance the understanding of the concept of perimeter in flat shapes among elementary school students. The study was conducted at TPA Nurul Iman involving 25 lower-grade students. The method used is qualitative through observation and learning outcome tests to understand students' interactions with learning media. The research results show that the use of origami boards has a positive impact on students' understanding of the concept of perimeter in plane figures. This media makes the learning process more interesting and interactive, thereby increasing student motivation and engagement. Students who struggle to solve problems using conventional methods show better understanding when using origami board media, as they can visualize mathematical concepts concretely. In addition to enhancing understanding, the use of origami boards also helps in developing students' critical thinking and fine motor skills. Practical activities applied in learning allow students to be more enthusiastic and actively engaged in the learning process. Thus, the use of origami board media has proven effective in enhancing students' understanding and learning outcomes related to the topic of the perimeter of flat shapes, and can be an alternative method for teaching mathematics in elementary schools.
