Penelitian ini bertujuan untuk meningkatkan keterampilan proses sains siswa kelas X5 SMA Negeri 6 Surakarta tahun pelajaran 2011/2012 melalui penerapan model pembelajaran kooperatif Group Investigation (GI). Penelitian ini merupakan penelitian tindakan kelas yang berlangsung dalam 2 siklus. Tiap siklus terdiri atas 4 tahapan dasar yaitu perencanaan, tindakan, observasi, dan refleksi. Pengumpulan data penelitian menggunakan lembar observasi, angket, dan wawancara. Validitas data diukur dengan menggunakan teknik triangulasi metode. Data yang telah didapat didukung dengan data hasil tes keterampilan proses sains siswa di akhir siklus. Teknik analisis data menggunakan teknik analisis deskriptif. Hasil penelitian menunjukkan bahwa berdasarkan lembar observasi rata-rata persentase capaian aspek keterampilan proses sains pada siklus I sebesar 52,57%, dan pada siklus II meningkat menjadi 80,36%. Persentase rata-rata aspek keterampilan proses sains berdasarkan hasil angket yaitu pada siklus I sebesar 84,22% dan pada siklus II sebesar 86,56%. Dari hasil wawancara siswa disimpulkan bahwa siswa dapat melaksanakan keterampilan proses sains pada pembelajaran. Data hasil tes keterampilan proses sains siswa pada siklus I, siswa yang mendapatkan nilai ≥ 70 sebesar 25%, dan pada siklus II sebesar 67,86%. Rata-rata kelas pada siklus I sebesar 60,27 dan pada siklus II naik menjadi 76,14. Simpulan dari penelitian ini adalah penerapan model pembelajaran kooperatif Group Investigation (GI) dapat meningkatkan keterampilan proses sains siswa kelas X5 SMA Negeri 6 Surakarta tahun pelajaran 2011 / 2012 The purpose of this research is to improve students’ science process skills in class X5 SMA Negeri 6 Surakarta in academic year 2011/2012 with implementation of Group Investigation cooperative learning model.
