Abstract

The research aims to determine the effectiveness of cooperative learning model type Think Talk Write (TTW) and type Think Pair Share (TPS) toward the mathematic communication skill students of grade 8th in MTs N Godean. This type of research is comparative descriptive which aplies Pretest Posttest Control Group Design. An instrument used in this study there are two kinds of the instruments learning and instruments data collection. An instrument consisting of learning implementation lesson plans and sheets of student activity, instruments gather data consists of broad observation, questionnaire, a test (pretest and posttest) and documentation. Analysis of data on research use t test some help software Ms. Excel 2010 and SPSS 20. The results of research pretest and posttest show that experiment class with cooperative model type Think Talk Write (TTW) and control class with cooperative model type Think Pair Share (TPS) normal distribution, both classes are homogenous and both classes have the same initial capability. The cooperative learning model type Think Talk Write (TTW) is same effective with cooperative learning model type Think Pair Share (TPS) toward the mathematic communication skill students. The level of effectiveness cooperative learning model type Think Talk Write (TTW) is 0,30 with medium category and the level of effectiveness cooperative learning model type Think Pair Share (TPS) is 0,28 with low category. Cooperative learning model type Think Talk Write (TTW) is same effective with cooperative learning model type Think Pair Share (TPS) because the students are individually active role in group discussions and there is the same syntax for these two models namely stage think.Keyword: Cooperative learning model type Think Talk Write (TTW), cooperative learning model type Think Pair Share (TPS), mathematic communication skill students.

Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas model PMRI dengan model pembelajaran kooperatif untuk peningkatan keterampilan berfikir matematis siswa. Melalui pembelajaran matematika, siswa diharapkan memiliki kemampuan berfikir logis,  analitis, sistematis, kritis, dan kreatif, serta memiliki kemampuan bekerjasama. PMRI adalah model pembelajaran yang bertitik tolah dari hal-hal yang real bagi siswa, menekankan keterampilan “proses of doing mathematics”. Penelitian ini merupakan penelitian jenis penelitian Quasi-Experimental, dimana kelas kontrol diberikan perlakuan pembelajaran matematika melalui model kooperatif, sedangkan kelas eksperimen diberikan perlakuan model PMRI. Berdasarkan Muhammadiyah 3 Yogyakarta untuk rata-rata nilai post test berfikir matematis kelompok eksperimen adalah 83.22 sedangkan untuk kelompok kontrol 58.58. Sedangkan di SMP Negeri 16 Yogyakarta nilai post test berfikir matematis kelas eksperimen sebesar 75.65, dan kelas kontrol 54.45. Berdasarkan hasil uji hipotesis perbedaan kemampuan berfikir kritis menggunakan uji t (independent samples T-Test) diperoleh nilai signifikan 0,000 dengan taraf signifikan 2%, diperoleh kesimpulan Ho ditolak, sehingga terdapat hasil perbedaan antara kelompok eksperimen setelah dikenakan Model PMRI. Berdasarkan uji pengaruh model pembelajaran masing-masing diperoleh t hitung di SMP Muhammadiyah 3 Yogyakarta 0,292 dan SMP Negeri 3 Yogyakarta 0,346 dimana semua nikai tersebut lebih besar dari t tabel, sehingga Ho dengan hipotesis terdapat pengaruh model PMRI terhadap peningkatan kemampuan berfikir matematis.Kata kunci: Model Kooperatif, Model PMRI, Kemampuan Berfikir Matematis
