The ability to understand mathematical concepts plays an important role in students' skills and success in learning mathematics. However, in reality, quite a few students have the stigma that mathematics is difficult and scary. This causes a low ability to understand mathematical concepts due to the application of learning strategies that are not appropriate to the abstract field of mathematics and the diverse characteristics of students. The application of content differentiation learning can be a solution to this problem. Mathematics learning aims to turn abstract reasoning into concrete. Visual media as a tool in the differentiated learning process can help students think concretely, explore various mathematical concepts, encourage students to participate actively, and provide meaningful experiences in the learning process to increase understanding of mathematical concepts. The aim of this research is to analyze the relationship between differentiated learning and students' ability to understand concepts in geometry material on the data side in visual form. This research refers to descriptive research with a qualitative approach with a literature review method through exploration of articles related to the research topic. Then carry out research sourced from trusted literature, namely articles, books and research results from experts to answer how the application of differentiation learning with visual media affects students' ability to understand concepts in Polyhedron Material.

In line with the results of the study Syarifuddin & Nurmi . At the activities in the ability to understand junior high school level, grouping mathematical concepts. In addition to students' abilities and needs in the encouraging the understanding of mathematical concepts, visual media can also build a cool learning understanding of concepts in the atmosphere so that students feel learning process. So that with the increasing understanding of concepts participation in learning with visual media can make students think more Student eliminate the stigma of mathematics as The consistent use of various difficult learning and can eliminate types of models and visual media learning activities. This will have a learning is proven to improve the good impact on students' mathematics ability to understand mathematical learning outcomes (Laia, 2. Understanding This can be described by concepts encourages students to be able to improve their reasoning skills. important factor is the selection of the By turning abstract mathematical right media. Each type of media has its concepts into concrete. Students with characteristics, so it needs to be matched with the context of the dominant in mathematics learning, material to be taught. A careful because by utilizing visual media successful use of visual media in First. Careful and good planning is mathematical concepts (Sabrina et al. characterized by integrating the use of visual media in the curriculum. The preparing relevant material. differentiated learning with content Testing the validity of visual student motivation, understanding of media is carried out by experts in the concepts, effectiveness, and learning This is a process that can ensure Validity tests and direct that the visual media used meet quality trials in the field prove that the success standards and are in accordance with of visual media is measured by mathematics education at the junior attractiveness, effectiveness, validity, high school level. The effectiveness of and significantly improved learning visual media is proven in improving the ability to understand mathematical CONCLUSION Good Grouping students' abilities animation, and interaction between and needs in the implementation of teachers and students in learning differentiated learning can improve activities can improve students' ability students' understanding of concepts in to understand mathematical concepts. the learning process. So that with the Thus, considering the selection increasing understanding of concepts of suitable media, good learning eliminate the stigma of mathematics as effectiveness in improving the ability difficult learning and can eliminate to understand concepts and student learning activities. This will have a important role in the use of visual good impact on students' mathematics media at the junior high school level in learning outcomes, mathematics learning. Visual media in Understanding concepts encourages students to be able to improve their reasoning skills. audiovisual are consistently proven to By turning abstract mathematical provide good results in understanding concepts into concrete. The positive the concepts of junior high school influence of implementing visual The use of visual media not only increases student participation activities in the ability to understand actively, but has a positive impact on mathematical concepts. In addition to encouraging the understanding of Based mathematical concepts, visual media described above, several suggestions can also build a cool learning were formulated as follows: atmosphere so that students feel Teachers should apply variations in Student teaching and learning activities, by participation in learning with visual practicing making learning media media can make students think more tailored to students. So as to create Thus, it can be concluded that the learning experience application of visual media is proven Teachers should attend training on to improve the ability to understand learning media, to deal with various mathematical concepts of junior high student learning styles with each school students. characteristic and develop their Merdeka Pada Pelajaran Matematika SD.
