<![CDATA[This research aimed to investigate whether cooperative learning model of three-step interview type can increase students’ mathematical communication skill. This research design was pretest-posttest control design. This research population was all students of grade 8th of SMPN 1 Gadingrejo in academic year of 2013/2014 that was distributed into 10 classes. This research samples were students of VIII.1 and VIII.2 class who were taken by purposive sampling technique. Based on data analysis, it was found that students’ mathematical communication skill who followed cooperative learning model of three-step interview type was higher than direct learning model. Thus, it can be concluded that cooperative learning model of three-step interview type can increase students’ mathematical communication skill.Penelitian ini bertujuan untuk mengetahui apakah model pembelajaran kooperatif tipe three-step interview dapat meningkatkan kemampuan komunikasi matematis siswa. Desain penelitian ini adalah pretest-posttest control design. Populasi penelitian ini adalah seluruh siswa kelas VIII SMP Negeri 1 Gadingrejo tahun pelajaran 2013/2014 yang terdistribusi ke dalam 10 kelas. Sampel penelitian adalah siswa kelas VIII.1 dan VIII.2 yang dipilih dengan teknik purposive sampling. Berdasarkan hasil analisis data diperoleh bahwa peningkatan kemampuan komunikasi matematis siswa yang mengikuti model pembelajaran kooperatif tipe three-step interview lebih tinggi daripada model pembelajaran langsung. Dengan demikian, dapat disimpulkan bahwa model pembelajaran kooperatif tipe three-step interview dapat meningkatkan kemampuan komunikasi matematis siswa.Kata kunci: kemampuan komunikasi matematis, pembelajaran langsung, three-step interview]]>
