Pengaruh Pendekatan Pendidikan Matematika Realistik Indonesia (PMRI) Terhadap Hasil Belajar Siswa Pada Materi Penjumlahan Dan Pengurangan Pecahan Berpenyebut Berbeda Di Kelas V Sekolah Dasar

Abstrak

This study aims to prove the influence of Indonesian realistic mathematics education approach (PMRI) on student learning outcomes in the additional operating material and reduction of fractional marks differ in class V SD Gugus III Ampek Angkek. This research is quantitative research with the experimental method and quasi experiment design. The sample technique used was the cluster sampling cluster sampling technique, while the population consisted of several elementary schools in Ampek III groups, So that the one who was chosen as the experimental class was a class V of SD Negeri 01 Koto Tuo and class V of SD Negeri 18 Sitapung as a control class. Based on the results of the average post-test of the experimental class using the Indonesian realistic mathematics education approach approach is 76.73 and the control class that uses conventional learning has the average post-test learning outcome of 58.05. Based on the results of the hypothesis test using the T-test (T-Test), the results of tcount 7.921 and ttable 2,080 with a significant level of 0.05. So tcount 7.921> t table 2,080. Thus it can be concluded that there is a significant difference between the two groups, so it is evident that the learning approach of the Indonesian realistic mathematics education (PMRI) has a positive effect on the results of the additional learning and reduction of different fractions in the class V of SD Gugus III Ampek Angkek.
