Penerapan Model Pembelajaran Inkuiri Terbimbing untuk Melatihkan Keterampilan Berpikir Kritis Peserta Didik pada Materi Kesetimbangan Kimia

Guided Inquiry Learning Model Application to Train Critical Thinking Skills Students on Chemical Equilibrium Material

Penelitian ini bertujuan untuk mendeskripsikan keterlaksanaan pembelajaran, aktivitas siswa, hasil belajar siswa, kemampuan berpikir kritis siswa dan respon siswa terhadap model pembelajaran inkuiri terbimbing pada materi kesetimbangan kimia. Desain penelitian yang digunakan adalah One Group Pretest Posttest Design. Subjek penelitian ini adalah 30 siswa kelas XI di SMA Kemala Bhayangkari 1 Surabaya. Penelitian menujukkan hasil sebagai berikut: (1) Keterlaksanaan pembelajaran untuk pertemuan 1, 2, dan 3 berturut-turut sebesar 96,9%, 98,6% dan 100%. (2) Aktivitas siswa mendukung keterlaksanaan model pembelajaran inkuiri terbimbing dengan persen total aktivitas yang relevan sebesar 92,69%. (3) Hasil belajar siswa pada faktor yang mempengaruhi pergeseran arah kesetimbangan kimia dengan n-gain diperoleh skor 80% dalam kategori tinggi. (4) Hasil kemampuan berpikir kritis siswa pada masing-masing komponen dengan skor n-gain kategori tinggi adalah interpretasi sebanyak 53,33%, inferensi sebesar 40%, analisis sebanyak 63,33%, eksplanasi sebanyak 60% dan evaluasi sebanyak 80%. (5) Respon siswa memiliki hasil kategori sangat baik dengan persentase 99,15%.

The purpose of this study is to explain the application of studying, activities of students, the products of student learning, students' skills in critical thinking, and student reactions to the model of guidance in inquiry learning on chemical equilibrium material. The design of this study applies One Group Pre-test Post-test Design. 30 students of class XI at Kemala Bhayangkari 1 Surabaya Senior High School were used as the subject of this study. This study obtained the some results, as follows: (1) The application of learning for meetings 1, 2, and 3 was 96.9%, 98.6, and 100%, respectively. (2) Student activities support the application model called guidance in inquiry learning model with a percentage of the total relevant activities of 92.69%. (3) Student learning outcomes on factors that affect the shift in the direction of chemical equilibrium with n-gain obtained a score of 80% which is high in the category. (4) The results of students' skills in critical thinking in every part with a high n-gain score are interpretation as much as 53.33%, inference by 40%, analysis as much as 63.33%, an explanation as much as,60% and evaluation as much as 80%. (5) Student responses have a very good category with a percentage of 99.15%.
