Penerapan Model Problem Based Learning Berbantuan Permainan Egrang untuk Meningkatkan Keterampilan Berpikir Kritis Peserta Didik pada Materi Energi Mekanik

Application Of the Problem Based Learning Model with The Assistance of The Steel Game to Improve Students' Critical Thinking Skills on Mechanical Energy Materials

Penelitian ini bertujuan untuk meningkatkan keterampilan berpikir kritis peserta didik melalui penerapan model Problem Based Learning (PBL) berbantuan permainan egrang pada materi energi mekanik. Desain penelitian menggunakan Non-equivalent Control Group Design yang termasuk ke dalam kelompok quasi eksperimental. Subjek pada penelitian ini adalah peserta didik SMA Negeri 1 Kalitidu kelas X-3 sebagai kelas kontrol dan peserta didik kelas X-4 sebagai kelas eksperimen. Instrumen penelitian terdiri dari lembar observasi keterlaksanaan, lembar tes keterampilan berpikir kritis, dan lembar respons peserta didik. Hasil penelitian menunjukkan bahwa penerapan model PBL berbantuan permainan egrang terlaksana dengan kategori sangat baik. Keterampilan berpikir kritis yang diukur dengan uji prasyarat, N-Gain, uji-t berpasangan dan perhitungan effect size dari kelas eksperimen termasuk pada kategori tinggi. Rata-rata respons peserta didik pada kelas eksperimen memiliki respons positif dengan kategori sangat baik. Hasil yang signifikan terkait keterampilan berpikir kritis peserta didik sebelum dan sesudah diberikannya penerapan model PBL berbantuan permainan egrang pada materi energi mekanik dengan penilaian keterlaksanaan serta respons peserta didik yang termasuk dalam kategori sangat baik membuat pembelajaran tersebut dapat dilanjutkan dan dikembangkan dalam pembelajaran fisika maupun pembelajaran lainya.

This research aims to improve students' critical thinking skills through the application of the Problem Based Learning (PBL) model assisted by stilt games on mechanical energy material. The research design uses a Non-equivalent Control Group Design which is included in the quasi-experimental group. The subjects in this research were students from SMA Negeri 1 Kalitidu class X-3 as the control class and students from class X-4 as the experimental class. The research instrument consists of an implementation observation sheet, a critical thinking skills test sheet, and a student response sheet. The results of the research show that the implementation of the PBL model assisted by stilts was carried out in the very good category. Critical thinking skills as measured by the swimmer's test, N-Gain, paired t-test and effect size calculations from the experimental class are in the high category. The average response of students in the experimental class was positive in the very good category. Significant results related to students' critical thinking skills before and after the implementation of the PBL model assisted by stilt games on mechanical energy material with an assessment of the implementation and responses of students which are included in the very good category means that learning can be continued and developed in physics learning and other learning.
