Analysis of Critical Thinking Skill Through Conceptual Change Model Learning Assisted with PhET Simulation

The aims of this research were 1) to analyze the level of critical thinking skills of students through learning based on the Conceptual Change Model (CCM) assisted by PhET simulation on momentum and impulse material; 2) to determine the differences in critical thinking skills between students who received learning with CCM assisted by PhET simulations and students who received conventional learning. The type of this research is a quasi-experimental research design with Posttest Control Group Design. The study population was all students of class X MIPA SMAN 1 Ngaglik with the sampling technique using simple random sampling. The research sample was students in class X MIPA 2 which were used as the experimental class and students in class X MIPA 1 as the control class. Critical thinking skills are obtained using multiple-choice tests and description tests. The aspects of critical thinking that are measured are basic clarification, inference, analysis, evaluation, and explanation. The analysis in this study uses descriptive statistics and independent t-test. Statistical test results provide a conclusion that there are differences in students' critical thinking skills in the experimental class with the control class. The critical thinking skills of students in the experimental class are higher than those of students in the control class for aspects of basic clarification, inference, evaluation, and explanation. As for the analysis aspect, the control class students were higher than the experimental class. The Critical thinking skill in the experimental class is good with an average of 68.03 and the control class in the moderate category
