The n-gain test results obtained in the experimental class 0, 12 and the control class -0.044 and based on the results of the hypothesis test using the independent sample t-test test that has been carried out obtained a value of 0.000. Based on the results of the n-gain test and hypothesis testing that the thinking ability of students is more improved in the experimental class so that there is an effect of using theproblem-based learning  modelon the thinking ability of students on substance pressure material.
