ABSTRAKPenelitian ini merupakan penelitian eksperimen semu yang bertujuan untuk mengetahui perbedaan hasil belajar matematika siswa yang diajar dengan model pembelajaran kooperatif Team Games Tournament (TGT) dan Blended Learning pada siswa SMA Negeri 3 Medan. Populasi dalam penelitian ini adalah seluruh siswa kelas X SMA Negeri 3 Medan semester II T.P. 2017/2018 yang terdiri dari 10 kelas paralel. Sampel penelitian ini adalah kelas X MIA 4 sebagai kelas eksperimen I yang telah diajarkan materi trigonometri dengan menggunakan model pembelajaran kooperatif tipe TGT dan kelas X MIA 3 sebagai kelas eksperimen II yang telah diajarkan materi trigonometri dengan menggunakan model pembelajaran kooperatif tipe Blended Learning dimana masing-masing jumlah sampel 32 orang dalam tiap kelas. Penelitian ini menggunakan instrumen tes yaitu pretest dan posttest yang berbentuk uraian yang telah divalidasi oleh tim ahli. Dari hasil analisis data pretest disimpulkan bahwa kedua sampel mempunyai kemampuan awal yang sama. Nilai rata-rata posttest pada kelas TGT adalah 89 dengan nilai terendah 76 dan nilai tertinggi 84. Nilai rata-rata posttest pada kelas Blended Learning adalah 78,81 dengan nilai terendah 66 dan nilai tertinggi 94. Dari uji hipotesis data posttest pada kedua sampel diperoleh t> t( 7,3238 > 1,66667) artinya bahwa hasil belajar matematika siswa yang diajar dengan model pembelajaran kooperatif tipe Team Games Tournament (TGT) lebih tinggi dibandingkan dengan hasil belajar matematika siswa yang diajarkan dengan model pembelajaran Blended Learning di kelas X SMA Negeri 3 Medan T.A 2017/2018.

ABSTRACTThe main problem of this study was the lack of ability in problem solving of junior high school (SMP) students about Comparison. To improve this ability, it was used the cooperative learning model of Number Head Together (NHT) type with approaching of problem based learning. The problem formulations would be studied in this study namely: Whether the cooperative learning model of NHT type with approaching of problem based learning influenced the students' skills in problem solving of comparison lesson. For the purposes of this study were to: (1) describe the implementation of cooperative learning model of NHT type with approaching of problem based learning; (2) describe an improvement in problem solving ability of students in comparison taught by using cooperative learning model of NHT type and approaching of problem based learning. Design of this study was two-group pretest-posttest design. The population was all students of class VII SUMBUL. Ability of mathematical problem solving of students was measured by using test of ability of problem solving. But looking for quality of the improvement obtained from two groups was conducted by testing on the index gain. The result of study showed that the ability of mathematical problem solving between students who were taught by using cooperative learning model of NHT type with approaching of problem based learning was higher than students who were taught just by problem based learning. It showed that there was the influence of cooperative learning model of NHT type with approaching of problem based learning to ability of mathematical problem solving. Based on the result of this study, it was suggested that teachers taught the mathematical problem solving by using cooperative learning model of NHT type with approaching of problem based learning.Key Words: Cooperative Learning Model of NHT Type; Approaching of Problem Based Learning; Ability of Problem Solving.
