Abstract

Penelitian ini mengkaji efektivitas integrasi Engineering Design Process (EDP) ke dalam model pembelajaran STEM untuk meningkatkan kesadaran energi terbarukan dan kemampuan berpikir kritis siswa SMP melalui proyek turbin angin. Desain penelitian yang digunakan adalah quasi-experimental non-equivalent pretest–posttest dengan total 62 partisipan: 31 siswa di kelas eksperimen yang menerapkan STEM dengan EDP, dan 31 siswa di kelas kontrol yang menerapkan STEM tanpa EDP. Data dikumpulkan melalui angket kesadaran dan tes berpikir kritis, sementara kinerja siswa juga dinilai untuk melihat korelasinya dengan variabel utama. Analisis data dilakukan menggunakan uji Wilcoxon, Mann–Whitney, t-test, N-Gain, dan analisis korelasi. Hasil penelitian menunjukkan bahwa model STEM-EDP secara signifikan meningkatkan kesadaran energi terbarukan, terutama pada aspek pengetahuan dan kesadaran, dampak lingkungan, serta sikap dan opini. Kemampuan berpikir kritis siswa juga meningkat secara substansial, khususnya pada keterampilan menyimpulkan, mengevaluasi pernyataan, mengidentifikasi asumsi, dan melakukan observasi, dengan ukuran efek yang besar (η² = .412). Meskipun kinerja siswa secara umum lebih tinggi pada kelompok eksperimen, tidak ditemukan korelasi yang signifikan antara kinerja siswa dengan kesadaran maupun berpikir kritis. Secara keseluruhan, integrasi EDP dalam STEM terbukti efektif dalam memperkuat keterampilan kognitif siswa, dengan kebutuhan perbaikan lebih lanjut pada aspek keterlibatan afektif, refleksi, dan manajemen waktu. This study investigated the effectiveness of integrating the Engineering Design Process (EDP) into STEM learning model to enhance middle school students’ renewable energy awareness and critical thinking through wind turbine projects. A quasi-experimental non-equivalent pretest–posttest design was employed with a total of 62 participants: 31 students in the experimental class, which implemented STEM with EDP, and 31 students in the control class, which applied STEM without EDP. Data were collected using awareness questionnaires and critical thinking tests, while student performance was assessed to examine its correlation with the main variables. The data were analyzed using Wilcoxon, Mann–Whitney, t-tests, N-Gain, and correlation analyses. The findings indicated that the STEM-EDP model significantly improved renewable energy awareness, particularly in awareness and knowledge, environmental impact, and attitudes and opinions. Students’ critical thinking skills also increased substantially, especially in inferring, evaluating statements, identifying assumptions, and observation, with a large effect size (η² = .412). Although student performance was generally higher in the experimental group, no significant correlation was found between student performance and either awareness or critical thinking. Overall, integrating EDP into STEM proved effective in strengthening students’ cognitive skills, with further refinement needed to support affective engagement, reflection, and time management.
