The Effect of Project Based Learning Model’s on Critical Thinking Skills, Creative Thinking Skills, Collaboration Skills, & Communication Skills (4C) Physics in Senior High School

Abstract

This study aims to (1) determine the differences in students^ critical thinking, creative thinking, collaboration, & communication (4C) skills due to the effect of implementing project based learning (PjBL) models with conventional learning, (2) determine the improvement of students^ critical thinking, creative thinking, collaboration, & communication (4C) skills due to the application of the project based learning (PjBL) model. The type of research used in this research is quasi-experimental. The population in this study were all students of class XI MIA MAN Tapanuli Selatan T.P 2020/2021. The sampling was done by cluster random sampling by taking 2 sample classes. The instruments used in this research are test instruments in the form of descriptions for critical thinking skills and creative thinking and non-test instruments in the form of observations for validated communication and collaboration skills. The data analysis used was the Manova test for critical thinking skills and creative thinking skills, whereas the N-gain analysis was used for communication and collaboration skills. Based on the results of data analysis, it was found that the 4C skills of students taught by the PjBL model were better than the 4C skills of students taught by conventional learning. The N-gain percentage in students^ critical thinking skills are increased by 75.40% (high category), students^ creative thinking skills are increased by 90.78% (high category), students^ collaboration skills are increased by 15.37% (low category), and students^ communication skills are increased by 80% (high category).
