Penelitian ini dilatarbelakangi oleh rendahnya keterampilan pemecahan masalah matematis siswa sekolah dasar pada pembelajaran matematika. Peneliti menerapkan pendekatan Realistic Mathematics Education untuk meningkatkan keterampilan pemecahan masalah matematis siswa. Tujuan penelitian ini adalah (1) mendeskripsikan pelaksanaan pembelajaran dengan menerapkan pendekatan Realistic Mathematics Education untuk meningkatkan keterampilan pemecahan masalah matematis siswa kelas II sekolah dasar. (2) mendeskripsikan peningkatan keterampilan pemecahan masalah matematis siswa kelas II sekolah dasar setelah menerapkan pendekatan Realistic Mathematics Education. Metode penelitian yang digunakan adalah metode penelitian tindakan kelas yang mengadopsi model Kemmis - McTaggart. Penelitian dilakukan dengan dua siklus. Subjek penelitian ini berjumlah 29 siswa kelas II sekolah dasar. Instrumen penelitian yang digunakan terdiri dari lembar observasi dan lembar evaluasi. Berdasarkan hasil observasi pada setiap siklus menunjukkan bahwa proses pembelajaran matematika dengan menerapkan pendekatan Realistic Mathematics Education mengalami perubahan yang cukup positif dari siklus pertama ke siklus kedua. Hasil analisis terhadap keterampilan pemecahan masalah matematis siswa didapatkan data yang menunjukkan nilai rata-rata pada siklus I adalah 50,2. Nilai rata-rata meningkat pada siklus II menjadi 68,1. Persentase ketuntasan belajar siswa pada siklus I yang sebesar 25,59% mengalami peningkatan pada siklus II menjadi 55,17%. Berdasarkan hasil tersebut, penerapan pendekatan Realistic Mathematics Education dapat meninkatkan keterampilan pemecahan masalah matematis siswa sekolah dasar. ------------ This study was conducted according to the low mathematical problem solving of elementary school students in learning mathematics. Researchers applied Realistic Mathematics Education approach to improve mathematical problem solving of students. The objectives of study were (1) to describe the implementation of learning by applying Realistic Mathematics Education agreement to improve mathematical problem solving skills of second grade elementary school students and (2) to describe the improvement of mathematical problem solving skills of second grade elementary school students after Implementing Realistic Mathematics Education. The study method was a classroom action research method adopted from the Kemmis - Mc Taggart model. The study was conducted in two cycles. The subject of this study discussed 29 students in second grade elementary school. The study instrument consisted of observation sheets and evaluation sheets. The result of observations in each cycle showed that the process of learning mathematics by applying Realistic Mathematics Education thinking had a positive impact from the shifting of first cycle to the second cycle. Data analysis of mathematical problem solving skills of students showed the mean value in the first cycle was 50.2. The mean value increased to 68.1 in the second cycle. The percentage of student who able to complete learning in the first cycle of 25.59%. This value had increased to 55.17% in the second cycle. Thus, the implementation of the Realistic Mathematics Education approach could improve mathematical problem solving skills of elementary school students.
