In present times, students need to have critical thinking skills. These can be developed through innovative learning models that not only emphasize their active participation but also facilitate the process of assimilating initial knowledge with new ones gained. One of these models developed as a tool in this research is a guided inquiry model combined with an advanced organizer. The purpose of this study, therefore, was to examine the effect of the combined model on improving students' critical thinking skills. The research subjects were divided into two classes, namely experiment, and control. Data on students' critical thinking skills were collected using a descriptive test, and analyzed by calculating normalized gain scores and hypothesis testing using the t-test with a significant level of 0.05. Hypothesis testing indicates that a guided inquiry model combined with advanced organizers influences students' critical thinking skills. Furthermore, the results of the average value of n-gain critical thinking skills of the experimental class students are higher than that of the control class. In general, it can be concluded that the guided inquiry model is effective in improving students' critical thinking skills.
