Model Pembelajaran Kooperatif Tipe Think Pair Share Untuk Meningkatkan Kemampuan Menghitung Pecahan

Tujuan penelitian ini untuk meningkatkan kemampuan menghitung pecahan melalui model pembelajaran Kooperatif tipe Think Pair Share pada siswa kelas V SDN Banjarsari Boyolali tahun ajaran 2015/2016. Bentuk penelitian ini adalah penelitian tindakan kelasyang berlangsung selama dua siklus. Subjek penelitian ini adalah siswa kelas V SDN Banjarsari Boyolali tahun ajaran 2015/2016 yang berjumlah 33 siswa. Teknik pengumpulan data adalah dokumentasi, observasi, wawancara, dan tes. Validitas data adalah triangulasi sumber dan triangulasi teknik, serta validitas isi. Teknik analisis data adalah analisis interaktif, teknik deskriptif komparatif, dan teknik analisis kritis. Berdasarkan hasil penelitian dapat disimpulkan bahwa penerapan model pembelajaran Kooperatif tipe Think Pair Share dapat meningkatkan kemampuan menghitung pecahan. Peningkatan kemampuan menghitung pecahan tersebut dapat dibuktikan dengan meningkatnya nilai kemampuan menghitung pecahan siswa pada setiap siklus, yaitu nilai rata-rata kemampuan menghitung pecahan siswa pratindakan hanya sebesar 60,83. Pada siklus I nilai rata-rata kemampuan menghitung pecahan siswa menjadi 72,28 dan pada siklus II meningkat lagi menjadi 86,96. Sebelum dilakukan tindakan, siswa yang memperoleh nilai diatas KKM hanya 10 siswa (30,30%). Pada siklus I meningkat menjadi 22 siswa (66,66%) dan pada siklus II meningkat lagi menjadi 30 siswa (90,90%).The purpose of this research is to improve calculate fractions ability through learning model of Cooperative type Think Pair Share in fifth grade of SDN Banjarsari Boyolali in the academic year of 2015/2016. This research was classroom action research, it conducted in two cycles. The subject of this reseacrh were the fifth grade of SDN Banjarsari Boyolali in the academic year of 2015/2016 as many as 33 students. The technique of collecting data was documentation, observation, interview, and test. The data validity was triangulation of resources and triagulation of technique, as well as the validity of the content. The technique to analyze data was interactive analysis model (Milles and Huberman), comparative descriptive technique and techniques of critical analysis. Based on result of the research, it can be concluded that using Cooperative type Think Pair Share can improve calculate fraction ability. Improvement of the students could be seen in the increased calculate fraction ability among the students for the each cycle, that are before the action, the average value calculate fraction ability among students was 60,83. In the first cycle, the average value increased to 72,28 and in the second cycle the average grade increased to 86,96. Before action of the research, students who acquired KKM grade were 10 students (30,30%). In the first cycle, the number of students increased to 22 students (66,66%) and in the second cycle the number of students increased again became 30 students (90,90%)
