This research aims to test the effect of using the Nearpod educational web based on Problem Based Learning on the critical thinking abilities of class V students at SDN Kembaran. The research method used is quantitative with a one group pretest-posttest research design. The research subjects involved 22 students in class V. The research instruments were an initial test (pretest) and a final test (posttest) which were used to measure critical thinking skills before and after the Nearpod problem-based learning intervention. Data collection was carried out by giving a test in the form of a description of 10 questions which had been tested for validity, reliability, level of difficulty and distinguishing power. Data analysis used descriptive statistical methods and inferential analysis with paired t-test to measure significant differences between pretest and posttest results. The research results showed an increase in the average pretest score of 60.2 while the posttest was 84. Based on the results of the normality test using the Pearson Shapiro Wilk correlation, it can be seen that the Pearson Correlation value obtained a pretest value of 0.527 and a posttest value of 0.548. Both mean they have a strong correlation and mean the data is normally distributed. The results of the correlation test between the pretest and posttest scores show that the probability is 0.000 < 0.50 (5% significance level), so Ho is rejected so it can be concluded that there is a relationship (correlation) between problem-based learning media nearpod and critical thinking skills.
