The results of the independent sample t-test (2-tailed) < 0.05, which is 0.000; 2) The SAVI learning model is less effective in improving students' critical thinking skills. The N-Gain result for the experimental class is 59%; 3) There is an influence between the SAVI learning model on students' learning interest, the results of Sig (2-tailed) < 0.05, which is equal to 0.000, while the SAVI learning model has no influence on students' critical thinking skills, the results of Sig (2-tailed) > 0.05, namely of 0.903.
