The research data consist of quantitative and qualitative. Quantitative data in the form of the average score of pretest, posttest, and N-Gain as a result of critical thinking skills were analyzed by independent sample t-test (α=0.05) using SPSS 25.0 For Windows. The results showed that there was a significant effect of application of the HOTS-based guided inquiry learning model on students' critical thinking skills during online learning (Sig. 0.010 < 0.05). The experimental class N-gain value of 0.65 is classified as medium category.
