Efektivitas Pendekatan Realistic Mathematic Education Ditinjau dari Pemahaman Konsep Matematis Siswa

This research aimed to find out the effectiveness of Realistic Mathematic Education approach in terms of students understanding of mathematical concepts. The population of this research was students of grade VII in SMP Negeri 1 Adiluwih in academic year of 2016/2017 that were distributed into 6 classes. The samples of this research were students of VII A and VII B class which were chosen by purposive and random sampling technique. The design was posttest only control group design. Analysis data of the research used t-test. Research data were obtained through test of understanding of mathematical concepts. Based on the result of the research, it was concluded that Realistic Mathematic Education approach was not effective in terms of students' understanding of mathematical concepts. But, the students understanding of mathematical concepts which was taught by Realistic Mathematic Education approach was better than students understanding of mathematical concepts which was not taught by Realistic Mathematic Education approach.Penelitian ini bertujuan untuk mengetahui efektivitas pendekatan Realistic Mathematic Education ditinjau dari pemahaman konsep matematis siswa. Populasi penelitian ini adalah seluruh siswa kelas VII SMP Negeri 1 Adiluwih tahun pelajaran 2016/2017 yang terdistribusi dalam 6 kelas. Sampel penelitian ini adalah siswa pada kelas VII A dan VII B yang diambil dengan teknik purposive dan teknik random sampling. Desain yang digunakan adalah posttest only control group design. Analisis data penelitian ini menggunakan t-test. Data penelitian diperoleh melalui tes pemahaman konsep matematis. Berdasarkan hasil penelitian, disimpulkan bahwa pendekatan Realistic Mathematic Education tidak efektif ditinjau dari pemahaman konsep matematis siswa. Namun, pemahaman konsep matematis siswa yang mengikuti pembelajaran dengan menggunakan pendekatan realistic mathematic education lebih tinggi daripada pemahaman konsep matematis siswa yang mengikuti pembelajaran tanpa menggunakan pendekatan realistic mathematic education.Kata kunci: efektivitas, pendekatan realistic mathematic education, pemahaman konsep matematis
