Enhancing Critical Thinking And Problem Solving Skills By Complexity Science-Problem Based Learning Model

Abstract

Critical thinking and problem-solving are fundamental skills that students need to master. Various learning obstacles that occur during the pandemic of Covid-19 have hindered critical thinking and problem-solving skills training. This study aimed to enhance students' critical thinking and problem-solving skills through Complexity Science-Problem Based Learning (CS-PBL) model. The research applied quasi-experimental with Nonequivalent Pre-test-Post test Control Group Design. The research sample consisted of 27 students in the experimental CS-PBL group, 29 students in the PBL group, and 26 students in the direct learning group. The instrument used in the research was an essay test of critical thinking integrated with problem-solving. Data were analyzed using ANCOVA followed by an LSD test. The results showed that the CS-PBL model enhanced students' critical thinking and problem-solving skills (p<0.05). Therefore, the CS-PBL model is applicable to facilitate the enhancement of critical thinking and problem-solving skills in the post covid-19 pandemic.
