PENERAPAN PENDEKATAN RME UNTUK MENINGKATKAN KEMAMPUAN PEMAHAMAN KONSEP MATEMATIS SISWA IV SEKOLAH DASAR

Abstract

This research is motivated by how low the students ability in understanding the mathematical concepts. Specifically in restating a concept, using, utilizing and choosing a particular procedure or operation, and applying a problem-solving concept or algorithm. This study aims to describe: (1) The teaching-learning process by applying the Realistic Mathematics Education learning approach to improve the ability to understand mathematical concepts of four grade students of elementary school, and (2) The improvement of fourgrade students’ ability in understanding the mathematical concepts by applying the Realistic Mathematics Education approach. Participants in this study were 27 four grade students at an elementary school in Sukajadi Sub-District of Bandung City in 2018/2019 school year. This research uses the Classroom Action Research method (CAR) with the Kemmis and Taggart models which are carried out in two cycles with circumference and area of planes learning materials. This research uses the principles of the Realistic Mathematics Education approach including 1) Didactical Phenomenology, 2) Guided Reinvention; and 3) Self Developed Model. The results showed an increase in students' understanding of concepts in the first cycle the average value of class 81 with a percentage of 81.48%. In the second cycle, the average value is 90 with a percentage of 96.30%. Thus it can be concluded that applying the Realistic Mathematics Education approach in elementary schools can improve students' understanding of mathematical concept skills
