Abstract
Pembelajaran Fisika Gelombang (PFG) dilaksanakan melalui implementasi model eksperimen open-inquiry. Tujuan utama penelitian ini untuk menguji keefektivan model eksperimen open-inquiry untuk mengembangkan keterampilan berpikir kritis mahasiswa. Penelitian ini menggunakan metode penelitian eksperimen pendidikan. Subjek penelitian adalah dua kelompok belajar yang terdiri dari 27 mahasiswa (eksperimen) dan 38 mahasiswa (kontrol) tahun 2011. Data penelitian tentang eksperimen open-inquiry dan keterampilan berpikir kritis dikumpulkan dengan lembar observasi dan panduan penilaian laporan, dan kuesioner untuk tanggapan mahasiswa. Hasil penelitian yaitu:1) skor rerata kemampuan eksperimen gelombang open-inquiry 80 (tutorial) dan 78 (tanpa tutorial) (skala 100), 2) hasil uji beda t diperoleh 2,205 (p < 0,05) dan uji t sampel tunggal diperoleh 10,15 (p < 0,01), yang menunjukkan kemampuan bereksperimen kedua kelompok berbeda secara signifikan, 3) skor rerata keterampilan berpikir kritis 80 (tutorial) dan 78 (tanpa tutorial), 4) hasil uji beda t diperoleh 1,864 (p < 0,05) dan uji t sampel tunggal diperoleh 8,34 (p< 0,01), yang menjelaskan keterampilan berpikir kritis kedua kelompok berbeda secara signifikan. Kesimpulan penelitian adalah implementasi model eksperimen gelombang open-inquiry efektif untuk mengembangkan keterampilan berpikir kritis mahasiswa fisika.
The Waves  Physics Learning (WPL) is carried out through implementation of an open-inquiry experiment waves model. The main objective is to examine of effectiveness of an implementation model and to develop of physics’ students critical thinking skills. This research used developmental research model. These data of the implementation experiment and the critical thinking skills were collected by observation sheets, assessment guidelines, and questionnaires for student responses. The results were 1) average score of an open-inquiry experiment model are 80 (tutorial) and 78 (non tutorial) (100 scale); 2) result of t test  2.205 ( p < 0.05) and one sample t test  10.15 (p<0.01) show that achievement in experiment between two groups was significantly difference; 3) average score of critical thinking skills are 80 and 78 (100 scale), 4) results of t test 1.864 (p<0.05) and t test one sample 8.34 (p<0.01) show that achievement in experiment between two groups was significantly difference (reguler) (100 scale). It can be concluded that the implementation of an open-inquiry experiment waves model effective to develop the critical thinking skills physics students.
