This type of research is quasi-experimental research. The population of this study consisted of students of class X IPA MAS PAB 1 Sampali. The sample of this study consisted of 26 students for the experimental class and 26 for the control class. The data acquisition technique used is testing. The results showed that the creative thinking ability of the students in the experimental class that used the Treffinger learning model was higher than the control class that used traditional learning. This means that the creative thinking ability of the experimental class is 8.46. While the control is 7.77. These data are supported by statistical analysis where t cout = 2.155. Looking at the test criteria for 5% level we get t-table = 2.006 where the t-test criteria are more significant than t-table = 2.155 > 2.006 so H0 is rejected i.e. Ha is accepted.
