The Effectiveness of Physics Learning Online Based on Guided Discovery Models to Improve Critical Thinking Skill

Abstract

Critical thinking skill is one of the abilities that must be possessed by students in the 21st century. Online learning combined with guided discovery models, is intended to be able to improve students' critical thinking skills at the high school level. This study aims to look at the effectiveness of online learning based on guided discovery models on the material of momentum and impulses to improve the critical thinking skils of high school students in class X. The research method uses quasi experimentation. The results of the study for experimental class 1 with the help of the LMS Schoology effect size score of 1.971758665 in the high category and experimental class 2 with the help of WhatsApp Application Group effect size score of 2.12844972 in the high category
