While the mastery of the concept of the experimental group is 81% with high criteria and the control class is 33% with medium criteria. The results of the t-test for mastery of concepts and critical thinking skills show that the experimental class is significantly higher than the control class with a value of tcount = 4.28 > ttable = 1.671 then Ho or the hypothesis is rejected.
