Based on the results and discussion, it concluded that (1) the learning outcomes of students taught by using inquiry training model are higher than students taught by using group investigation model, (2) there is interaction effect between the application of learning model and critical thinking skill towards learning outcomes of science, (3) the learning outcomes of students taught by using inquiry training model are higher than students taught by using group investigation model on group of the students who have high critical thinking skill, and (4) the learning outcomes of students taught by using inquiry training model are lower than students taught by using group investigation model on group of the students who have low critical thinking skill. The result of this research indicates that inquiry training model with critical thinking skill able to improve learning outcomes of science.
