This research aims to: Analyzing the effect size of different learning models on mathematical critical thinking abilities. This type of research is a meta-analysis research with a sample size of 8 journals indexed in Sinta RistekDikti and filtered through coding. The results showed that: Of the eight studies that met the criteria for a meta-analysis of different mathematics learning models in improving junior high school students' mathematical critical thinking abilities, the highest effect size with a value of 0,8247 was a problem-based learning model. So that the model is considered more effective in improving the mathematical critical thinking abilities of junior high school students. The results of the analysis with the random effect model show that there is a significant positive correlation between the learning model and the students' mathematical critical thinking abilities (z = 5,785 < 0,001; 95% CI [0.480; 0.971]) with the mean effect size of the effect of the learning model on mathematical critical thinking abilities, included in the large category with r _RE = 0.725.
