Permasalahan pembelajaran IPA di SMP Negeri 2 Singaraja adalah rendahnya hasil belajar IPA pada siswa kelas VIII. Penelitan ini bertujuan 1) mendeskripsikan hasil belajar IPA siswa yang mengikuti model pembelajaran kooperatif tipe Snowball Throwing berbantuan multimedia interaktif, 2) mendeskripsikan hasil belajar IPA siswa yang mengikuti model pembelajaran konvensional, dan 3) mengetahui perbedaan yang signifikan hasil belajar IPA antara siswa yang mengikuti model pembelajaran kooperatif tipe Snowball Throwing berbantuan multimedia interaktif dengan siswa yang mengikuti model pembelajaran konvensional di kelas VIII semester genap tahun pelajaran 2014/2015 di SMPN 2 Singaraja. Jenis penelitian ini adalah penelitian eksperimen semu dan menggunakan rancangan Posttest-Only Control Design. Populasi penelitian adalah seluruh kelas VIII SMPN 2 Singaraja yang berjumlah 588 orang dengan sampel kelas VIII.12 dan VIII.14. Data yang dikumpulkan adalah hasil belajar siswa. Instrumen yang digunakan adalah tes objektif. Data dianalisis dengan menggunakan statistik deskriptif dan statistik inferensial (uji-t). Hasil penelitian menunjukkan: (1) hasil belajar IPA siswa yang mengikuti model pembelajaran kooperatif tipe Snowball Throwing berbantuan multimedia interaktif menunjukkan skor rata-rata 24,96 berada pada kategori sangat tinggi, (2) hasil belajar IPA siswa yang mengikuti model pembelajaran konvensional menunjukkan skor rata-rata 16,39 berada pada kategori sedang, (3) terdapat perbedaan yang signifikan hasil belajar IPA antara kelompok siswa yang belajar menggunakan model pembelajaran koperatif tipe Snowball Throwing berbantuan multimedia interaktif dengan kelompok siswa yang belajar menggunakan model pembelajaran konvensional (thitung = 10,645 > ttabel = 1,665).
