IMPLEMENTASI MODEL PEMBELAJARAN INKUIRI TERBIMBING UNTUK MELATIH KETERAMPILAN PROSES BERPIKIR KRITIS PADA SISWA KELAS XI SEKOLAH MENENGAH PADA MATERI KESETIMBANGAN

IMPLEMENTATION OF THE GUIDED INQUIRY LEARNING MODEL TO TRAIN CRITICAL THINKING PROCESS SKILLS FOR CLASS XI SENIOR HIGH SCHOOL STUDENTS ON EQUILIBRIUM MATERIAL

Penelitian ini bertujuan untuk mengetahui keterlaksanaan model pembelajaran inkuiri terbimbing, untuk mengetahui aktivitas peserta didik, keterampilan berfikir kritis peserta didik, dan respon peserta didik terhadap model pembelajaran yang telah diterapkan. Penelitian ini menggunakan metode penelitian One Group Pretest-Postest Design dengan sampel penelitian dengan jumlah peserta didik sebanyak 36 peserta didik kelas XI Mipa 4 SMA Al-Islam Krian Sidoarjo. Perangkat yang digunakan dalam penelitian ini adalah silabus, Rencana Pelaksanaan Pembelajaran, serta Lembar Kerja Peserta Didik. Lembar observasi keterlaksanaan model pembelajaran, lembar pengamatan aktivitas peserta didik, lembar pretest dan postest dan lembar respon peserta didik merupakan instrumen penelitian yang digunakan. Hasil dari penelitian ini yaitu : (1) Keterlaksanaan model pembelajaran mendapatkan nilai 91,11% pada pertemuan 1, 94,99% pada pertemuan 2, 99,29% pada pertemuan 3 dengan kriteria sangat baik. (2) Aktivitas peserta didik pertemuan 1 yaitu 96,23%, pertemuan 2 yaitu 97,40%, pertemuan 3 yaitu 99,11%. (3) Hasil uji normalitas menunjukkan nilai signifikasi yaitu 0,083 > 0,05 maka dapat disimpulkan bahwa data terdistribusi normal. Hasil analisis menggunakan uji Paired Sample T (T-test) mendapatkan nilai signifikasi 0,000 < 0,05 maka dapat disimpulkan bahwa terdapat perbedaan rata-rata antara hasil Pretest dan Postest. (4) Hasil respon peserta didik mendapatkan respon positif dengan persentase rata-rata jawaban sebesar 99,44% dan mendapatkan respon negatif dengan persentase rata-rata jawaban sebesar 0,62%.

The main goal of this research was to discover how the guided inquiry learning model was implemented, as well as students' activities, critical thinking abilities, and responses to the learning model that was used. The One Group Pretest-Posttest Design was employed in this research, which used research sample of 36 students in class XI of Mathematics and Natural Science 4 Al-Islam High School Krian Sidoarjo. The tools used in this research were the syllabus, lesson plans, and student worksheets. The research instruments used were the observation sheet on the implementation of the learning model, the student activity observation sheet, the pretest and posttest sheets and the student response sheet. The results of this research were as follows: (1) The implementation of the learning model received a score of 91.11% at meeting 1, 94.99% at meeting 2, 99.29% at meeting 3 with very good criteria. (2) The activity of students in the first meeting was 96.23%, the second meeting was 97.40%, the third meeting was 99.11%. (3) The results of the normality test showed a significance value of 0.083 > 0.05, so it could be concluded that the data was normally distributed. The results of the analysis using the Paired Sample T test (T-test) got a significance value of 0.000 <0.05, so it could be concluded that there was an average difference between the results of the Pretest and Posttest. (4) The results of student responses received a positive response with an average percentage of answers of 99.44% and received a negative response with an average percentage of answers of 0.62%.
