This correlational research aims to reveal the contribution of critical thinking skills (CTS) toward cognitive learning outcomes (CLO) on the learning using NHT and metacognitive strategies, and to reveal the differences in regression equations between the two learning models. The results revealed that there was a correlation between CTS and CLO in both the NHT and metacognitive strategies. The biggest contribution of CTS toward the students' CLO was found in the NHT + metacognitive strategy learning model, which was 71.4%, and the regression equation of the learning model was Y = 21.66 + 0.72 X. The results of Anova show the significance value of b1, b2 was 0.009 (p <0.05) and the significance value of b1, b2, b3 was 0,000 (p <0.05). Thus, the rate and magnitude of the student CLO as an effect of the CTS are different from each other. These results prove the NHT learning model and metacognitive strategy is more effective in empowering CTS and CLO.
