Implementation of Project-Based Learning Model in Improving Students' Critical Thinking Skills

Abstract

Critical thinking skills are one of the important competencies that students must have in facing the challenges of the 21st century. However, the learning process in schools is still dominated by conventional methods that are centered on teachers, so it does not provide space for students to develop high-level thinking skills. This study aims to examine the implementation of the project-based learning model (PjBL) in improving students' critical thinking skills. The research method used is a quantitative approach with a quasi-experimental design. The research subjects were students at the high school level who were divided into experimental classes and control classes. The research instruments are in the form of critical thinking tests and observation sheets of learning activities. Data were analyzed using descriptive and inferential statistical tests. The results of the study show that the application of the PjBL model has a positive and significant influence on improving students' critical thinking skills compared to conventional learning. Thus, the PjBL model can be used as an innovative learning alternative that is effective to improve the quality of learning in schools.
