Abstract

Membangun jiwa kewirausahaan ke dalam diri peserta didik perlu dilakukan untuk membentuk kemandirian peserta didik. Penelitian ini bertujuan untuk menkonstruk jiwa kewirausahaan peserta didik dengan menerapkan project based learning berbasis STEMC. Penelitian terdiri dari 52 orang peserta didik kelas X IPA disalah satu SMAN Kota langsa. Jiwa kewirausahaan peserta didik diukur melalui angket kemudian diuji menggunakan paired sample t-test secara statistik dan uji N-gain. Hasil penelitian menunjukkan penerapan model PjBL berbasis STEMC pada materi elektrolit dan nonelektrolit dapat meningkatkan jiwa kewirausahaan dilihat dari hasil taraf signifikan 0,000 dengan nilai sig <0.05 yang menunjukkan adanya perubahan secara signifikan dan hasil perhitungan N-gain skor rata-rata jiwa kewirausahaan yaitu 0,14. Proses Pembelajaran menggunakan model PjBL berbasis STEMC dapat membentuk pengetahuan awal dengan pengetahuan baru peserta didik dalam menciptakan produk kewirausahaan sehingga menkonstruk jiwa kewirausahaan dalam diri peserta didik

Abstract

The rapid development of science and technology in the 21st century necessitates an educational approach that fosters students' critical thinking, problem-solving, and conceptual mastery skills, particularly in complex topics such as colloids. This study aims to examine the effectiveness of applying a STEM-based guided inquiry approach in colloid practicums on improving students' conceptual mastery. The research design used was a quasi-experimental pretest-posttest control group study involving 34 second-semester students in the Chemistry Education Program at UIN Ar-Raniry. The research instruments consisted of a two-level multiple-choice concept mastery test and a STEM learning effectiveness questionnaire. The study was conducted over six weeks through several colloid laboratory sessions. Statistical analysis using ANCOVA (p < 0.005) showed a significant difference in posttest scores between the experimental and control groups. The high effect size (Cohen's d = 0.8) indicates that this approach has a significant impact on student learning outcomes, particularly in developing higher-order thinking skills at levels C4 to C6. This study indicates that integrating a contextual, student-centered STEM-based learning model into chemistry laboratory sessions can enhance conceptual understanding and 21st-century skills. However, limitations such as a small sample size, research location restricted to a single institution, and relatively short treatment duration should be considered when generalizing the study's findings. Further research with a longitudinal design and a broader sample scope is highly recommended.
