So that mathematics is mentioned by many scholars as the queen of all sciences. In the world of education mathematics also supports other sciences such as physics, biology and so on. The role of mathematics in life can be very easy to find, starting from very simple things such as buying and selling, money as a means of transacting and socializing in life. One of the compulsory subjects in formal education which has a very important position and role is mathematics. This is in line with Dumciuvience (2015) which states that in terms of future growth a country depends on knowledge. Competition in the future will certainly grow in the framework of the rapid development of one's knowledge. An educated society is expected to be able to compete with countries in a world full of competition. Through effective education the civilization of a nation is built. 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 ) 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.Įducation is a very important aspect for the life of a nation. So that the model is considered more effective in improving the mathematical critical thinking abilities of junior high school students. 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. This type of research is a meta-analysis research with a sample size of 8 journals indexed in Sinta RistekDikti and filtered through coding. This research aims to: Analyzing the effect size of different learning models on mathematical critical thinking abilities.
