Pengaruh Model Project Based Learning Terhadap Kemampuan Berpikir Kritis Siswa Sekolah Dasar

Abstract

This study aims to examine the effect of the Project Based Learning (PjBL) model on elementary school students’ critical thinking skills. Employing a quasi-experimental design with a non-equivalent control group, the research involved 26 fifth-grade students at SDN Cimanggu III. Students in the experimental group were taught using the PjBL model, while those in the control group received conventional instruction. Critical thinking was assessed through a test developed based on Facione’s indicators: interpretation, analysis, evaluation, inference, and explanation. The findings revealed a statistically significant difference between the two groups (p < 0.05), with the experimental group achieving higher post-test scores. These results demonstrate that PjBL effectively enhances students’ critical thinking through project engagement, collaborative learning, and reflective activities. Therefore, the PjBL model can be considered a pedagogical approach that promotes 21st-century competencies, particularly critical thinking, among elementary learners.
