Abstract
This study aims to analyze the mathematical representation ability of junior high school students in the material on flat shapes on the new normal area. The learning process is currently being carried out face-to-face in schools. However, to prevent and spread Covid-19 in schools, learning is carried out alternately with 50 percent face-to-face learning and 50 percent independently at home. This research is qualitative descriptive research. The subjects in the study to analyze the mathematical representation abilities of these students were grade VII students in the second semester of the 2020/2021 academic year in Dharmasraya, West Sumatra with a sample of 20 students. The instruments used in this study were tests of students mathematical representation abilities and interviews. Each question contains indicators of students^ mathematical representation ability. The indicators measured are visual representation, expression representation, and word representation. Based on the research conducted, it was found that the level of students^ mathematical representation ability was still low (52.65). In general, students still experience problems in using their mathematical representation skills, students must be able to sharpen their representation skills both in visual representation, symbol representation, and verbal representation. By mastering mathematical representation skills, it can make it easier for students to solve mathematical problems, and there will be fewer conceptual errors.
