Abstract


This research aims to analyze (1) the differences of students critical thinking skills using problem posing models and conventional models, (2) the differences of students critical thinking skills before and after using problem posing models and conventional models, and (3) the effectiveness of the problem posing model towards students critical thinking skills of geography subject in XI Social Science class of SMAN 13 Bandar Lampung. This research uses quasi-experimental with cross design. The subjects of this research are students in XI Social Science class of SMAN 13 Bandar Lampung. Data collection techniques in this research use tests and documentation, while data analysis techniques that are used in this research are Two Way Variants (ANOVA), and Effect Size. The results indicate that there are differences in students' critical thinking skills after studying with problem posing models and conventional models. The differences are tested by two way variance analysis and the result of sig value is 0.009 <0 , 05 . The result also indicates that the problem posing model is more effective for improv students critical thinking skills of geography subjects in XI Social Science class of SMAN 13 Bandar Lampung.
