Abstract

ABSTRAK Tujuan penelitian ini untuk mengetahui apakah ada pengaruh pendekatan Science, Technology, Engineering and Mathematics (STEM) berbasis desain rekayasa terhadap kemampuan berpikir IPAS peserta didik kelas IV di SDN 4 Rejosari Natar. Pendekatan yang digunakan kuantitatif dengan jenis penelitian kuantitatif eksperimen menggunakan desain quasi-exsperimental design. Desain quasi exsperimental yang digunakan dalam penelitian ini ialah Pretest Posttests Nonequivalent Control Group Desain. Penelitian ini menggunakan teknik pengumpulan data berupa tes yaitu soal essay berjumlah 11 soal. Populasi penelitian adalah seluruh peserta didik kelas IV di SDN 4 Rejosari Natar. dan data dalam penelitian ini dianalisis menggunakan uji prasyarat analisis, uji N-Gaint dan uji hipotesis dengan uji-T. Berdasarkan hasil penelitian dan perhitungan uji-T menggunakan SPPS 29.0 memperoleh hasil perhitungan bahwa nilai Sig 0,013. Karena nilai Sig berdasarkan perhitungan ialah 0,013 < 0,05. Maka dapat disimpulkan bahwa disimpulkan bahwa H1 diterima dan H0 ditolak. Artinya bahwa ada pengaruh dari pendekatan Science, Technology, Engineering and Mathematics (STEM) berbasis desain rekayasa terhadap kemampuan berpikir IPAS peserta didik kelas IV di SDN 4 Rejosari Natar. Kata Kunci: Pendekatan STEM Berbasis Desain Rekayasa, Kemampuan Berpikir Kritis IPAS. ii ` ABSTRACT The purpose of this study was to determine the effect of a Science, Technology, Engineering, and Mathematics (STEM) approach based on engineering design on the science thinking skills of fourth-grade students at SDN 4 Rejosari Natar. The approach used was quantitative, with a quasi-experimental design. The quasi experimental design used in this study was a Pretest-Posttest Nonequivalent Control Group Design. The data collection technique used was a test, consisting of 11 essay questions. The study population was all fourth-grade students at SDN 4 Rejosari Natar. The data were analyzed using prerequisite analysis, the N-Gaint test, and a t-test. Based on the research results and the t-test calculations using SPSS 29.0, the Sig value was 0.013. Since the Sig value based on the calculations is 0.013 <0.05, it can be concluded that H1 is accepted and H0 is rejected. This means that there is an influence of the Science, Technology, Engineering and Mathematics (STEM) approach based on engineering design on the science thinking skills of fourth grade students at SDN 4 Rejosari Natar. Keywords: STEM Approach Based on Engineering Design, Critical Thinking Skills in Science.
