Abstract

The ability to think critically can be improved through a learning process that uses teaching materials in the form of worksheets specifically designed on the material of global warming to increase students' critical thinking abilities. The purpose of the study was to describe the effectiveness level of SETS vision global warming worksheets in improving critical thinking skills. The research method used is quasi experiment with non-equivalent control group design. Test Hypothesis difference in N-Gain control class with experimental class using independent sample T-test statistical test and test the hypothesis of the difference in the average pretest and posttest using paired T-Test samples. The experimental class uses SETS vision worksheets, while the control class uses conventional worksheets. The test subjects were high school students in one of the city districts in Lampung Province. Experimental class N-Gain results are higher than the control class. In the experiment class the average posttest score was higher than the pretest. Learning about global warming using SETS vision worksheets is effective in improving the critical thinking skills of high school students.
