Pengaruh Pendekatan Pendidikan Matematika Realistik terhadap Kemampuan Penalaran Matematis Siswa Kelas V pada Materi Bangun Ruang

Abstract

The results of the PISA in 2018 where Indonesia take place 72th of 79th country. One of the factors is the learning that has not pay attention to aspects of students' mathematical reasoning abilities. RME approach is emphasize on creative thought process and involves student’s reasoning abilities.This research aims to determine the influence of the Indonesia’s Realistic Mathematics Education approach on mathematical reasoning abilities students grade V on geometry lesson. The type of this research is one group pretest posttest design. The population consisted of 86 student who sat in class IV, V and VI then selected 12 children from class V as a sample that was given treatment with the RME approach. Technique to collect data using tests, interview, and questionnaires.The results of data analysis showed that students' mathematical reasoning increased from a pretest score 64 increased at posttest to 80. Then using analyze of paired sample t-test with ? = 0.05 obtained tcount = 7.881 > ttable = 2.201 so that H0 is rejected and Ha is accepted. Then it can be concluded that the Indonesia’s Realistic Mathematics Education approach is influence to the mathematical reasoning abilities of students grade V on geometry lesson.
