The subjects of this research are students of class XI MIPA 3 as the experimental and class XI MIPA 4 as the control class at SMAN 10 Pekanbaru. The method uses experimental research with a randomized control group pretest-posttest research design. The data obtained were analyzed using normality test, homogeneity test, hypothesis testing and N-Gain test. The results showed that the KAPRA learning model effectively increased students' critical thinking skills. Based on the hypothesis test, tcount > ttable (5.89 > 1.66) with the N-Gain value in the moderate category of 0.52.
