This study aims to determine the effect of multireperentation skills in cooperative learning model type Teams Games Tournament (TGT) on student physics learning outcomes. This research was conducted in SMAN 1 Seputih Raman, in the even semester of academic year 2016/2017, with One-Shot Case Study research design. The population of this research is all students of class XI IPA and sample of this research is 33 students of class XI IPA5. Research data obtained through the test using the description problem. From a simple linear regression test obtained coefficient of determination of 0.675. This means there is a positive and significant linear influence between multirepresentation skill in TGT cooperative learning to student physics learning result, that is equal to 67,5% with RSquare equal to 0,675.Keywords: Learning Outcomes, Multirepresentation Skills, Teams Games Tournament.AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh skill multirepersentasi dalam model pembelajaran kooperatif tipe Teams Games Tournament (TGT) terhadap hasil belajar fisika siswa. Penelitian ini dilakukan di SMAN 1 Seputih Raman, pada semester genap tahun ajaran 2016/2017, dengan desain penelitian One-Shot Case Study. Populasi penelitian ini adalah seluruh siswa kelas XI IPA dan sampel penelitian ini adalah 33 siswa kelas XI IPA5. Data penelitian diperoleh melalui tes soal uraian. Dari uji regresi linier sederhana diperoleh nilai koofisien determinasi sebesar 0,675. Hal ini berarti terdapat pengaruh linier yang positif dan signifikan antara skill multirepresentasi dalam pembelajaran kooperatif TGT terhadap hasil belajar fisika siswa, yaitu sebesar 67,5% dengan RSquare sebesar 0,675.
