ABSTRAKTujuan penelitian ini adalah untuk meningkatkan aktivitas siswa dalam pembelajaran matematika dengan menggunakan Realistic Mathematics Education (RME) di kelas VIII SMP Muhammadiyah 2 Prambanan. Penelitian dilakukan dua siklus. Teknik pengumpulan data yang digunakan adalah observasi, wawancara, dokumentasi dan triangulasi. Lembar observasi penelitian instrumen dan wawancara. Analisis instrumen menggunakan validitas isi. Analisis yang digunakan adalah deskriptif kualitatif. Hasil penelitian menunjukkan bahwa Realistic Mathematics Education (RME) dapat meningkatkan aktivitas belajar siswa Hal ini terbukti dari pengamatan aktivitas siswa dalam pembelajaran setiap siklus mengalami peningkatan, yaitu rata-rata persentase observasi aktivitas siswa pada siklus I 50,623% (cukup), dan pada siklus II meningkat menjadi 61.960% (baik). Dari hasil wawancara dengan siswa menunjukkan respon positif terhadap aktivitas belajar siswa.Kata kunci: realistis, RME, pembelajaran aktivitas siswa
ABSTRACTThe aims of this research is to increase student activity in learning mathematics by using Realistic Mathematics Education (RME) in class VIII SMP Muhammadiyah 2 Prambanan. The study was conducted two siklus. Data collection techniques used are observation, interview, documentation and triangulation. Instrument research observation sheet and interview. Instrument analysis using content validity. The analysis used is descriptive qualitative. The results showed that Realistic Mathematics Education (RME) can increase student learning activity This is evident from the observation of student activity in learning every siklus has increased, that is average of observation percentage of student activity in siklus I 50,623% (enough), and at siklus II increased to 61.960% (good). From the results of interviews with students showed a positive response on student learning activity.
The research was conducted because of low student activity in learning mathematics. The purpose of this research is to improve the activity of students in learning mathematics using the cooperative learning model of think pair square (TPS) in class VII of even semester at SMP Muhammadiyah 2 Prambanan. This research was conducted at SMP Muhammadiyah 2 Prambanan. The type of research is classroom action research. Subjects of this research were students of class VII of even semester at SMP Muhammadiyah 2 Prambanan academic year 2015/2016, amounting to 35 students. The object of the research is a cooperative learning model type TPS. Data analysis used qualitative descriptive analysis. The research instruments are student activity observation sheets, teacher activity observation sheets, and interview guides. Success in learning characterized by an increased average percentage of student activity achieved at least a good criteria (≥ 61 %). The result of this research indicates that the use of mathematical models of cooperative learning type of TPS can enhance student activity. From the observation sheet, there was an increase in student activity with the student in learning mathematics using TPS. In the first cycle, the average student activity reached 57,857% with enough criteria, and the second cycle increased to 64,584% with good criteria. From interview showed a positive response from students to use cooperative learning model type TPS.
