This study aims to determine the effect of the Accelerated Learning model based on the Truth or Dare game on the critical thinking skills of students in class XI Mas Ulumuddin. This type of research is Quasi Eksperiment with nonequivalent control group design research design. Sampling technique with purposive sampling technique, the sample of this study is class XI-D students as an experimental class and class XI-C as a control class. Data collection techniques in this research use test and non-test techniques (questionnaires). Meanwhile, data analysis uses prerequisite tests which include normality and homogeneity tests, hypothesis tests, and student response lift analysis. In the results of the student response questionnaire, there was an average percentage of about 71% who had attractive criteria. The results showed that the average value of the experimental pretest was 30.375 and the value of the control pretest was 28, while the average value of the experimental posttest was 74.625 and the value of the control posttest was 66.500. Based on the hypothesis test using an independent sample test on the pretest, a sig (2-tailed) result of 0.046 is smaller than the significance level of 0.05, meaning that H₀ is accepted. The results of this study show that the application of the Truth or Dare game-based Accelerated Learning model on static fluid material affects students' critical thinking skills.
