Effect of Problem Based Learning Model on Science Critical Thinking Ability of Elementary Students

This study aims to describe the effect of the Problem Based Learning model on the thinking skills of elementary school students. The research used is quantitative research with pre-experimental methods in the form of One Group Pretest Posttest Design, which uses one experimental class at SDN Kalisampurno 3. The data analysis technique in this study used the N - Gain test and the paired sample t - test. Based on the results of the t test that the sig. 2 tailed of 0.000 <0.05, meaning that there is an effect of the Problem Based Learning model on the critical thinking skills of grade V elementary school students and obtained the average N Gain score of 0.49 with a moderate category that there is an effect of the Problem Based Learning model on the critical thinking skills of grade V elementary school students SDN Kalisampurno 3 in the moderate category.
