ABSTRACT
This research started from the phenomenon of low critical thinking skill of grade XI IPS students in SMAN 9 Harjamukti Cirebon. Many factors influence, one of them is the learning method. The purpose of this research is to find the differences in students' critical thinking skill before and after using Problem Based Learning (PBL) learning method and Problem Solving (PS) learning method. This research is an experimental study using the Quasi Experiment method. The form of design of quasi experiment used is Nonequivalen Control Group Design. The research subjects are class XI IPS 1, XI IPS 2 and class XI IPS 4 in SMAN 9 Harjamukti Cirebon. Data collection tools for students' critical thinking skill are obtained by providing tests in the form of description questions. The test that will be used is done validity test, reality test, difficulty level test and differentiating test. Data processing techniques use normality test, homogeneity test, Gain and for hypothesis test using paired samples t-test and independent sample t-test. Based on the results of the study, it can be concluded that there are differences from students’ critical thinking skill using Problem Based Learning (PBL) and Problem Solving (PS) learning method is higher than the analytical capability of students who use conventional methods and there are differences in students' critical thinking skills between class that use Problem Based Learning (PBL) learning method and class that use Problem Solving (PS) learning method. Learning using Problem Solving (PS) learning method is more effective in improving students' critical thinking skill than learning using Problem Based Learning (PBL) learning method and conventional method.
Keywords: Problem based learning (PBL), problem solving (PS), students' critical thinking skill.
