摘要：Tujuan penelitian ini adalah untuk menyelidiki keefektifan model pembelajaran Teams Games Tournament terhadap kemampuan pemecahan masalah siswa kelas VII SMPN 8 Batang pada materi pokok pecahan. Pengambilan sampel dilakukan dengan cluster random sampling. Kelas eksperimen diberi perlakuan dengan menerapkan model pembelajaran Teams Games Tournament dan kelas kontrol dengan menerapkan model pembelajaran Konvensional. Metode pengumpulan data dalam penelitian ini menggunakan metode dokumentasi dan tes. Pengambilan data dilakukan dengan pemberian tes kemampuan pemecahan masalah pada akhir penelitian. Hasil penelitian menunjukkan bahwa rata-rata kemampuan pemecahan masalah kelas eksperimen adalah 77,4655,sedangkan rata-rata kemampuan pemecahan masalah kelas kontrol adalah 73,1207. Perhitungan memberi hasil bahwa kemampuan pemecahan masalah matematika siswa kelas eksperimen memenuhi ketuntasan belajar (,mencapai kriteria ketuntasan klasikal (,rata-rata kemampuan pemecahan masalah matematika kelas eksperimen lebih baik daripada kelas kontrol,serta persentase ketuntasan kelas eksperimen lebih baik daripada persentase ketuntasan kelas kontrol. Dengan demikian,dapat disimpulkan bahwa model pembelajaran TGT efektif terhadap kemampuan pemecahan masalah matematika siswa kelas VII SMPN 8 Batang pada materi pokok pecahan.
其他摘要：The purpose of this study was to investigate the effectiveness of the learning model Teams Games Tournament (TGT) on the problem-solving abilities class VII SMPN 8 Batang on the fractions subject matter. Sampling was conducted by cluster random sampling. Experimental class were treated by applying a learning model TGT and control class were treated by applying the learning model of Conventional . Methods of data collection in this research using the method of documentation and testing. Data is collected by administering the test problemsolving abilities at the end of the study. The result showed that the average of problem-solving ability on experimental class is 77.4655,while the average of problem-solving ability on control class is 73.1207. Test calculations gave result that ability mathematical problem-solving of experimental class meet mastery learning (≥65),ability mathematical problem-solving of experimental class achieve classical completeness criteria (≥85%),the average solving skills of mathematic problem on experiment class better than the control class,and the proportion solving skills of mathematic problem on experiment class better than the control class. Thus,it can be concluded that the model of learning TGT effective on problem-solving skills of students of class VII SMPN 8 Batang on the fraction subject matter.
