Pembelajaran Fisika dengan Model PBL Berbasis STEM untuk Meningkatkan Keterampilan Berpikir Kritis Peserta Didik SMA

Kehidupan di era abad-21 menuntut seseorang untuk mampu menguasai keterampilan 4C (colaboration, communication, critical thinking, and creativity) dan menuntun sumber daya manusia yang mampu bersaing secara global yang akan dilatih melalui pembelajaran fisika dengan model pembelajaran PBL (problem bassed learning) berbasis STEM (science, technology, engineering, and mathematics), sehingga penelitian ini bertujuan mendeskripsikan keterlaksanaan pembelajaran fisika dengan model PBL berbasis STEM untuk meningkatkan keterampilan berpikir kritis peserta didik SMA, mendeskripsikan hasil peningkatan keterampilan berpikir kritis peserta didik setelah diterapkan model pembelajaran PBL berbasis STEM, dan mendeskripsikan respon peserta didik terhadap penerapan model pembelajaran PBL berbasis STEM. Jenis penelitian ini adalah pre-experimental dengan desain penelitian one group pre-test and post-test. Subjek penelitian yaitu kelas X MIPA 2, X MIPA 3, dan X MIPA 5 SMA Muhammadiyah 1 Taman dengan jumlah keseluruhan sebanyak 72 peserta didik. Instrumen penelitian yang digunakan meliputi lembar pengamatan keterlaksanaan pembelajaran, lembar soal pre-test and post-test, dan angket respon peserta didik. Teknik analisis data yang digunakan diantaranya yaitu uji-t berpasangan, perhitungan n-gain, dan ANOVA. Hasil penelitian menunjukkan bahwa (1) keterlaksanaan pembelajaran PBL berbasis STEM terlaksana dengan sangat baik; (2) penerapan model PBL berbasis STEM dapat meningkatkan keterampilan berpikir kritis secara signifikan pada α = 0,05, dengan rerata n-gain berkategori tinggi, dan konsisten pada ketiga kelas; (3) respon peserta didik terhadap pembelajaran PBL berbasis STEM berkategori sangat baik

ABSTRACT

Physics Learning with STEM-Based PBL Model to Improve Critical Thinking Skills of High School Students

Life in the 21st-century era requires a person to be able to master the 4C skills (collaboration, communication, critical thinking, and creativity) and lead human resources who can compete globally which will be trained through physics learning with PBL (problem-based learning) learning model based on STEM (science, technology, engineering, and mathematics), So this study aims to describe the implementation of physics learning with STEM-based PBL models to improve the critical thinking skills of high school students, describe the results of improving students' critical thinking skills after applying STEM-based PBL learning models, and describe students' responses to the application of STEM-based PBL learning models. This type of research is pre-experimental with a one-group pre-test and post-test research design. The research subjects were classes X MIPA 2, X MIPA 3, and X MIPA 5 SMA Muhammadiyah 1 Taman with a total of 72 students. The research instruments used include learning implementation observation sheets, pre-test, and post-test questionnaires, and student response questionnaires. Data analysis techniques used include paired t-test, n-gain calculation, and ANOVA. The results showed that (1) the implementation of STEM-based PBL learning was very well implemented; (2) the application of the STEM-based PBL model can significantly improve critical thinking skills at α = 0.05, with the average n-gain in the high category, and consistent in all three classes; (3) students' responses to STEM-based PBL learning were very good.
