THE EFFECT OF PROBLEM-ORIENTED-PROJECT-BASED-LEARNING (POPBL) MODEL ON CRITICAL THINKING SKILLS AT SENIOR HIGH SCHOOL 1 CIBITUNG

Abstract

Critical thinking skills are essential 21st-century skills that need to be enhanced through innovative learning. Several studies indicate that students' critical thinking skills in various regions of Indonesia are still categorized as low. POPBL is an innovative learning model that has the potential to improve critical thinking skills. This study aims to analyze the effect of the POPBL model on high school students' critical thinking skills in biology learning. The research design used is a quasi-experimental design. The population of this study consists of all 11th grade MIPA students at high school 1 Cibitung. The classes used as research samples are class XI MIPA 7, taught with the POPBL model as the experimental group, and class XI MIPA 6, taught
with the PBL model as the control group. The sampling technique used is random sampling. The instrument used is an essay test on critical thinking skills, integrated with a 1-4 assessment rubric. Data analysis was conducted using ANCOVA. The results of the ANCOVA test show that the implementation of the Problem-Oriented Project-Based Learning (POPBL) model
has an effect on students' critical thinking skills in grade XI. Students who learned with POPBL had a higher average critical thinking score of 70.20, compared to students taught with PBL, who scored 53.18.
