Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui apakah kemampuan pemecahan masalah matematika siswa menggunakan model  pembelajaran kooperatif tipe TPS lebih tinggi daripada model pembelajaran tipe STAD di SMP Negeri 17 Medan. Populasi dalam penelitian ini adalah seluruh siswa kelas VII SMP Negeri 17 Medan yang terdiri dari 9 kelas dan sampel dalam penelitian ini adalah siswa kelas VII-2 dan siswa kelas VII-3 sebanyak 72 orang. Jenis penelitian ini adalah eksperimen semu. Data yang diperlukan diperoleh dengan menggunakan tes kemampuan pemecahan masalah matematika berupa uraian sebanyak 3 soal. Dari hasil analisis data diperoleh rata-rata hasil tes kemampuan pemecahan masalah matematika siswa melalui pembelajaran kooperatif tipe TPS adalah 18,94 dengan simpangan baku 6,72 dan rata-rata hasil tes kemampuan pemecahan masalah matematika siswa melalui pembelajaran kooperatif tipe STAD adalah 12,94 dengan simpangan baku 5,15. Untuk uji hipotesis digunakan uji t, dari hasil perhitungan diperoleh ????ℎ???????????????????? = 4,28 dengan kriteria pengujian tolak Ho dan terima Ha jika ????ℎ???????????????????? ≥ 1,66 sehingga terlihat bahwa ternyata ????ℎ???????????????????? tidak berada pada daerah penerimaan H0 yang berarti bahwa ???????? ditolak dan ???????? diterima atau dengan kata lain kemampuan pemecahan masalah matematika siswa menggunakan model  pembelajaran kooperatif tipe TPS  lebih tinggi daripada model pembelajaran kooperatif tipe STAD di SMP Negeri 17 Medan. Berdasarkan hasil penelitian ini, kemampuan pemecahan masalah matematika siswa yang diajar menggunakan model pembelajaran kooperatif tipe TPS lebih tinggi daripada model pembelajaran kooperatif tipe STAD.  Kata Kunci : kemampuan pemecahan masalah matematika, TPS, STAD  ABSTRACT This study aims to determine whether the problem solving skills of mathematics students using cooperative learning model of TPS type higher than STAD type learning model in SMP Negeri 17 Medan. The population in this study is all students of class VII SMP Negeri 17 Medan consisting of 9 classes and the sample in this study are students of class VII-2 and students of class VII-3 as much 72 people. This type of research is a quasi experiment. The required data is obtained by using a math problem solving test in the form of a description of 3 questions. From the results of data analysis obtained the average test results of students 'mathematical problem solving skills through cooperative learning type TPS is 18,94 with standard deviation 6,72 and the average test results of students' math problem solving skills through cooperative learning type STAD is 12,94 with standard deviation 5,15. To test the hypothesis used t test, from the calculation results obtained thitung = 4,28 with the test criterion reject Ho and accept Ha if thitung ≥ 1,66, so it seems that thitung not in the acceptance area H0 which means that H0 rejected and Ha accepted or in other words, students' mathematical problem solving ability using cooperative learning model of TPS type is higher than STAD type cooperative learning model in SMP Negeri 17 Medan. Based on the result of this research, the problem solving ability of student in mathematics that was taught using cooperative of TPS is higher than STAD.  Keywords: mathematical problem solving ability, TPS, STAD

Abstract

AbstractThe purpose of this study was to determine the increase in student learning outcomes on the subject of the system of linear equationswith two variables cooperative learning Numbered Head Together. 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
