Penerapan Model Pembelajaran Rme untuk Meningkatkan Pemahaman Konsep Pembelajaran Matematika Materi Diagram Batang pada Siswa Kelas 5 SD

Abstract

This study aims to apply the RME learning model to improve the understanding of mathematical concepts of bar diagram material in 5th grade elementary school students. The method used in the study is a classroom action research (CAR) method with the Kemmis and Mc Taggart research model from (Arikunto, 2015). The research steps according to Arikunto (2015) include: 1) planning, 2) action, 3) observation, 4) reflection. Data collection techniques include documentation, observation, and tests. The instrument in this study was a written test with multiple choice and descriptive formats. Quantitative data analysis used descriptive statistics. The results of this study show differences in the application of the RME model to student activities and the ability to understand mathematical concepts in cycle I and cycle II. Student activity in cycle 1 showed an average result of 66% and in cycle II increased to 77%. Meanwhile, students' understanding of the concept in cycle I was 66%, and their understanding of the concept in cycle II was 86.19%. The significant difference in percentages between cycles I and II, as seen from the percentage per cycle, indicates that the RME learning model is able to improve the understanding of mathematical concepts in bar diagrams for fifth-grade students at SDN Tanjungrejo 4. The findings of this study indicate that involving students in the learning process directly and providing space for reflection and collaborative discussion can improve students' understanding of mathematical concepts.
