The Application of Physics Learning Media Based on Android with Learning Problem Based Learning (PBL) to Improve Critical Thinking Skills

Abstract

One of the abilities that students must have in the 21st century is the ability to think critically. This study aims to see the use of Android-based physics learning media using PBL learning to improve critical thinking skills in Newton's Law material. This type of research is the pretest posttest control group design. The study was aimed at students of class X SMA Negeri 1 Tempilang with sample selection using random cluster sampling. The selected class is X MIPA 1 as the implementation class and X MIPA 2 as the control class. The data collection was in the form of a critical thinking skill test that was tested before and after learning. The collected data were analyzed using the N-gain test to determine the increase in critical thinking skills. The results of the N-gain analysis show that the Android-based physics learning media with the PBL model in the implementation class is in the high category, while the control class is in the medium category.The results of the analysis obtained that the use of Android-based physics learning media with PBL learning can improve students' critical thinking skills.
