PENERAPAN MODEL PEMBELAJARAN INKUIRI TERBIMBING UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS PESERTA DIDIK KELAS VIII PADA MATERI SISTEM PERNAPASAN MANUSIA 

APPLICATION OF THE GUIDED INQUIRY LEARNING MODEL TO IMPROVE THE CRITICAL THINKING ABILITY OF CLASS VIII STUDENTS IN HUMAN RESPIRATORY SYSTEM MATERIALS 

Penelitian ini bertujuan untuk meningkatkan keterampilan berpikir kritis peserta didik SMP melalui penerapan model pembelajaran Inkuiri Terbimbing pada materi Sistem Pernapasan Manusia. Penelitian ini dilaksanakan di SMP Laboratorium YDWP Unesa Surabaya. Jumlah partisipan dalam penelitian ini melibatkan sebanyak 24 peserta didik Kelas VIII-A. Jenis penelitian yang digunakan dalam penelitian ini adalah pre-eksperimental design, dengan menggunakan rancangan one group pretest posttest design. Teknik pengumpulan data yang digunakan adalah observasi, tes tertulis berupa pretest dan posttest, dan angket. Instrumen yang digunakan dalam penelitian ini di antaranya lembar observasi keterlaksanaan pembelajaran, lembar pretest dan posttest, serta lembar angket respon peserta didik. Analisis data dilakukan menggunakan statistika yaitu uji Normalitas, statistika inferensial (uji Wilcoxon) dan statistika deskriptif (uji N-Gain). Hasil penelitian menunjukkan bahwa (1) keterlaksanaan pembelajaran memperoleh skor rata-rata 3,07 dengan kategori baik, (2) nilai rata-rata N-Gain yang diperoleh sebesar 0,63 termasuk dalam kategori sedang, (3) angket respon peserta didik memperoleh rata-rata sebesar 84% dengan kategori sangat baik. Berdasarkan hasil yang diperoleh, dapat disimpulkan bahwa penerapan model inkuiri terbimbing dapat meningkatkan kemampuan berpikir kritis peserta didik.

This study aims to improve the critical thinking skills of junior high school students through the application of the Guided Inquiry learning model on the subject of the Human Respiratory System. This research was conducted at the YDWP Laboratory Middle School Unesa Surabaya. The number of participants in this study involved 24 Class VIII-A students. The type of research used in this study was a pre-experimental design, using a one group pretest posttest design. Data collection techniques used were observation, written tests in the form of pretest and posttest, and questionnaires. The instruments used in this study included observation sheets on the implementation of learning, pretest and posttest sheets, and student response questionnaire sheets. Data analysis was performed using statistics, namely the Normality test, inferential statistics (Wilcoxon test) and descriptive statistics (N-Gain test). The results showed that (1) the implementation of learning obtained an average score of 3.07 in the good category, (2) the average N-Gain score obtained was 0.63 included in the medium category, (3) the student response questionnaire obtained an average of 84% in the very good category. Based on the results obtained, it can be concluded that the application of the guided inquiry model can improve students' critical thinking skills.
