ABSTRAKPenelitian ini bertujuan untuk mengetahui perbedaan hasil belajar yang diajarkan dengan menggunakan modle pembelajaran kooperatif tipe TGT dengan hasil belajar yang diajarkan menggunakan model pembelajaran kooperatif tipe TPS pada materi Kubus dan Balok,siswa kelas VIII SMP N 2 Kotapinang T.A 2017/2018.Populasi penelitian ini adalah seluruh kelas VIII SMP N 2 Kotapinang yang terdiri dari 7 kelas. Jenis penelitian ini adalah eksperimen semu dengan instrumen berupa tes pilihan berganda yang telah valid dan reliabilitas tinggi yaitu 0,739 untuk soal pretest dan 0,988 untuk soal postest. Dari hasil analisis data pretest kelas eksperimen I diperoleh L0 = 0,142< Ltabel = 0,148 dan data pretest kelas eksperimen II diperoleh L0 = 0,134< Ltabel = 0,148. Maka dapat disimpulkan data pretest kedua kelas adalah berdistribusi normaL.Dari uji homogenitas data postest diperoleh bahwa kedua sampel homogen yaitu dengan Fhitung = 1,028 < Ftabel = 1,76.Setelah dilakukan uji hipotesis dengan uji t maka diperoleh thitung = 1,766 dan ttabel = 1,666. Hal ini berarti thitung > ttabel maka Ha diterima dan H0 ditolak. Maka dapat disimpulkan bahwa hasil belajar siswa yang diajar dengan model pembelajaran kooperatif tipe TGT lebih tinggi dari hasil belajar siswa yang diajarkan dengan model pembelajaran kooperatif tipe TPS siswa kelas VIII SMP N 2 Kotapinang.Kata kunci : hasil belajar matematika,model TGT,model TPS ABSTRACTThis research aims to finds the difference of mathematics achievement thought by cooperative type of TGT (Teams Games Tournament) and TPS(Think Pair Share) on cube and beam material.

Subjects in this study were class VIII-2 MTs Raudhatul Hasanah many as 31 people. The object of this research is the application of the cooperative model Numbered Head Together. The research instrument used by observation and tests. This type of research is a classroom action research. Before giving action, first given a diagnostic test to determine the ability and determination of the initial group of students based on ability level. The data provided in the form of shaped achievment test descipsion given twice at the end of each cycle. In this study the use of worksheets intended as teachingn tool to facilitate teaching and learning in cooperative groups. From the analysis of the data after a given action I (cycle I) obtained 23 out of 31 student (74,19%) reached mastery learning and 8 out of 31 students (25,80%) has not reached mastery learning with an average grade 68,70. In this cycle of learning completeness in classical yet achieved. From the analysis of the data after a given action II (cycle II) obtained 27 out of 31 students (87,10%) reached mastery learning, and 4 out 31 students (12,90%) has not reached mastery learning with an average grade 77, 09. In this cycle of learning completeness classically been reached. This means that an increase in student learning outcomes from cyle I to cycle II. Thus the implementation of cooperative learning model Numbered Head Together can improve student learning outcomes on the subject of the system of linear equations in two variables of class VIII MTs Raudhatul Hasanah.Keywords : Cooperative, Numbered Head Together, Raudhatul Hasanah

ABSTRACTThis study aims to determine the differences in the mathematical problem solving abilities of students who are taught with the Problem-Based Learning Model (PBM) and the Quantum Learning Model on cubes and blocks in class VIII SMP Negeri 9 Medan. This type of research is a quasi experiment. The sample taken is class VIII-1 as experimental class A, which is the class taught with the Problem Based Learning Model and class VIII-5 as the experimental class B, which is the class taught by the Quantum Learning Model. Before starting the treatment, the researcher saw the similarities in the initial conditions of experimental class A and experimental class B based on student report cards. Then the first procedure in this study is to give an initial ability test to the class under study, in order to see the students' initial abilities. From the results of the initial test obtained, it showed that the average value of student observations in the cube and block material was 34.75. After the posttest was carried out in both classes, the results obtained were the average value of the experimental class A of 65.184 and the average value of the experimental class B of 58.333. That is, the two classes of the research sample experienced different conditions regarding their mathematical problem solving abilities after receiving treatment. Based on hypothesis testing, it can be concluded that there are differences in the mathematical problem-solving abilities of students who are taught using the Problem Based Learning Model (PBM) with the Quantum Learning Model on Cube and Block material in class VIII SMP Negeri 9 Medan.
