This research aims to examine the effectiveness guided inquiry learning model based on blended learning on reaction rate material to improve students' critical thinking skills. The design in this research is the One Group Pretest and Posttest Design. The subjects in this research were students of SMAN 1 Kalitidu Bojonegoro in class XI IPA 1. The method used to collect data was the test, observation, and student response questionnaires. Data analysis used the percentage, mean, N-Gain, and Paired sample t-test. The results showed that the guided inquiry learning model based on blended learning was carried out well with an average percentage of the implementation of phase 1 was 98%, phase 2 was 93.76%, phase 3 was 100%, phase 4 was 93.75%, phase 5 was 100%. The average score of the N-gain critical thinking skills is 0.73 with the high category. There is a significant difference in the results of critical thinking skills between before and after being given a guided inquiry learning model based on blended learning. The results showed the guided inquiry learning model based on blended learning effectively improving students' critical thinking skills.
