The method used in this research was quasi-experimental method, which involves two classes, namely class A as an experimental class that was taught with ITG-DiA learning model and class C as a control class that was taught with a guided inquiry model. The purpose of implementing ITG-DiA model is to determine the effect of model on critical thinking skills and learning outcomes. The research instruments consisted of a critical thinking test with five essay question items, an affective assessment questionnaire, and a psychomotoric assessment questionnaire sheet. The instruments were validated by experts before being used. The results of validation of critical thinking tests were obtained test validity from 0.37 to 0.69. The results of the affective and psychomotor assessment questionnaire validation were valid. The results obtained an average value of critical thinking skills in experimental class were 87.11 and 79.44 in control class. The average values of learning outcomes were obtained 87.86 in experimental class and 82.58 in control class. In general, critical thinking skills and learning outcomes have increased. The improvement of learning outcomes and critical thinking skills have significant differences. The non-parametric test result of Mann Withney test was obtained Asymp.sig value ??< 0.05 or, 000 < 0.05, indicating that the critical thinking skills and learning outcomes of the two samples are different. Based on the differences in the results, it can be concluded that the application of ITG-DiA learning model affects the ability of critical thinking and learning outcomes.
