The purpose of this study was to determine the effect of learning models Double Loop Problem Solving (DLPS) to the ability problem solvimg mathematical students. This research was a quantitative research type of quasi experiment. The sampling technique that used was random class technique. The sampel in this research was the VII B grade as a experimental class and the VII E grade as a control class. Data analysis technique of this research was normality test, homogeneity test and hypothesis test by using one-party t-test. Based on the result of t-test analysis of one party with significant level 5% with description , So the result of the research can be concluded that there was influence of learning models Double Loop Problem Solving (DLPS) to the ability problem solving of mathematically.
