<![CDATA[This research aims to develop bilingual getrans teaching aids that can be used to visualise the concept of geometry transformation. The urgency of this research lies in the effort to facilitate students' understanding of abstract concepts in geometric transformations where the development of getrans teaching aids allows students to learn actively, involving physical and visual, which is believed to improve understanding and retention of concepts. Utilizing the 4D model, the Research and Development (R&D) approach is applied. The four phases of the 4D development model are defined, designed, developed, and disseminated. The findings showed that students had trouble grasping the idea of geometric transformation at the define stage. At the design stage, preparation for the development of bilingual getrans teaching aids was carried out. At the development stage, getrans props were made as well as validation of video results by experts and limited trials to students. Then at the dissemination stage, the revised video results were disseminated based on expert advice. The conclusion of this research is that bilingual getrans teaching aids can be used for learning mathematics which students can better understand changes in position, rotation, reflection, or dilation of objects in geometry with better.]]>

<![CDATA[The learning of mathematics generally undergoes a less effective and less appealing learning process, resulting in students’ perceived lack of mastery of the material. Consequently, students’ insufficient understanding of the concepts leads to a lack of folding back. In the process of understanding, it influences individual characteristics, where two characteristics are cognitive styles: field-dependent and field-independent. The researcher aims to understand how the folding back process occurs in students with field-dependent and field-independent cognitive styles when solving story problems. This research is a descriptive qualitative study, with 2 students selected from a total of 28 students in class VII-A as subjects. The selected subjects have high mathematical abilities and are classified into the categories of field-dependent and field-independent cognitive styles. Data collection involves comprehension tests, group embedded figure test (GEFT), and interviews. Data analysis consists of stages such as data reduction, data presentation, and verification. Each subject is interviewed to verify their process of solving the given problems. The results of the research conclude that students with the field-independent cognitive style category have a better understanding of the material, concepts, and problem-solving compared to students in the field-dependent category.]]>
