ANALISIS KEMAMPUAN REPRESENTASI MATEMATIS SISWA SMA DALAM MENYELESAIKAN SOAL CERITA BERBASIS MASALAH

Abstract

This research aims to determine students' mathematical representation abilities in solving problem-based story problems. The research method applied is a qualitative approach with a descriptive design. The population of this study was 24 students of class X MIPA 1 at SMA Negeri 1 Telukjambe Barat, and the sample taken was 3 students selected using a purposive sampling technique. The subject selection process is carried out to ensure that the sample reflects special characteristics or traits that are relevant to the research objectives. As a result, subjects were selected to represent categories of high, medium, and low mathematical representation ability. The data collection technique is in the form of a written test designed to measure students' mathematical representation abilities, with the test material focusing on sequences and series. The mathematical representation ability indicators measured involve visual, symbolic and verbal representations. The results show that students' ability to solve story problems is still moderate, with the potential to improve visual, symbolic and verbal skills; students in the high category can fulfill all representation indicators, while students in the low category require intervention to improve their understanding of mathematical word problems. The conclusion are the percentage of student achievement in visual and verbal aspects still being low, indicating the need for a learning approach that is more focused on developing visual representation abilities and verbally in the context of story problems to enrich students' experiences.
