The purpose of the study was to determine the effect of the problem based learning model (pbl) and cooperative two stay two stray (TSTS) on students’ critical thinking skills in elementary school mathematics learning. This type of research is quantitative, using experimental research methods with a population of fifth grade elementary school students in the Nusa Indah cluster. The research samples were taken from 3 elementary schools using random sampling technique. The design used a pretest – posttest. The sample consists of 35 students at SDN Ngawen (experimental class 1), SDN Ruwit 31 students (experimental class 2) and SDN Buko 28 students in the control class. Data collection using tests, hypothesis testing using t test, and F count 0.672 greater than F table 0.5138. Homogeneity and normality test, With experimental results 1, the average value of pre-test normality test results Lcount = 0.197 and experiment 2 obtained L = 0.138, then the data for the two experimental classes is normally distributed. Homogeneity test obtained an average of 0.55> 0.05, meaning that the class variance is the same or homogeneous. In the post-test experimental model 1, students achieved an average of 80.00, learning completeness 87.59% and observation results 87.50. Experimental model 2, class average 82.59, learning completeness 85.59% and observation results 88.9. The results showed that was an effect of treatment of problem based learning models and cooperative two stay two stray on students’ critical thinking skills because they met the criteria for the value obtained the KKM 70, so the hypothesis was accepted. There are differences due to the effect of the PBL and cooperative TSTS models on students’ critical thinking skills, The results of learning mastery of the PBL model are higher than the cooperative TSTS. For this reason, the teacher-centered learning process should be changed to student-centered.
