Abstract
Penelitian ini bertujuan untuk mengetahui apakah terdapat kemampuan komunikasi matematis siswa yang diajar dengan model pembelajaran Discovery Learning dan model pembelajaran Problem Based Learning di SMP Negeri 35 Medan T.A 2017/2018. Jenis penelitian ini adalah penelitian eksperimen. Dalam penelitian ini populasi yang diambil adalah seluruh siswa SMP Negeri 35 Medan Kelas VIII sebanyak 6 kelas. Pengambilan sampel dilakukan menggunakan teknik cluster sampling dan banyak sampel dalam penelitian ini terdiri dari 2 kelas, kelas pertama disebut sebagai kelas eksperimen I dengan model pembelajaran Discovery Learning dan kelas kedua disebut sebagai kelas eksperimen II dengan model pembelajaran Problem Based Learning dan jumlah siswa pada masing-masing kelas adalah 34 orang siswa untuk kelas eksperimen I dan 34 orang siswa untuk kelas eksperimen II. Instrumen yang digunakan dalam penelitian ini adalah soal tes kemampuan komunikasi matematis, yang terdiri dari 4 butir soal uraian. Tes diberikan sebanyak 2 kali yaitu pretest sebelum diberikan pembelajaran dan posttest diberikan setelah pembelajaran di kedua kelas berakhir. Dari hasil pengolahan data diperoleh rata-rata kemampuan komunikasi matematis siswa pada hasil pretest diperoleh 54,26 untuk kelas eksperimen I dan 54,85 untuk kelas eksperimen II. Sedangkan pada posttest rata-rata kemampuan komunikasi matematis siswa sebesar 82,65 untuk kelas eksperimen I dan 75,00 untuk kelas eksperimen II. Berdasarkan pengujian hipotesis yang dilakukan yaitu dengan mengggunakan uji dua pihak. Berdasarkan tabel hasil pengujian pada taraf signifikansi α = 0,05 dan dk =n1 + n2 - 2 = 66 dengan thitung = 3,16 dan ttabel = 1,669 , Ha diterima. maka berdasarkan pengujian tersebut diperoleh bahwa H0 ditolak berarti a H diterima sehingga dapat dinyatakan terdapat perbedaan kemampuan komunikasi matematis siswa yang diajar dengan model pembelajaran Discovery Learning dan model pembelajaran Problem Based Learning (PBL) di SMP Negeri 35 Medan T.A. 2017/2018.
