Abstract:
In 21st century learning, students are required to have 4C competencies, namely Critical Thinking, Collaboration, Creative and Communication .The ability to think critically in elementary school students needs to be trained so that students have the ability to make decisions in dealing with problems. Problem-Based Learning (PBL) is an example of a learning model that directs students to participate directly in solving a simple problem. The purpose of this study was to determine whether or not the problem-based learning (PBL) learning model had an effect on students' critical thinking skills at SDN 1 Kalibaru on social studies content. This type of research is a quasi-experimental design using a non-equivalent control group design. In this design, it begins with giving a pretest to the two groups. And given a posttest at the end of the experimental and control groups to see changes for different actions. This research was conducted at SDN 1 Kalibarukulon with the research subjects, namely all students of class IVA and class IVB who previously had homogeneity tests.Data collection techniques include observation, interviews, documentation and tests. The results showed that the posttest results of the control class were 70.2% while the experimental class was 81%. The results of the hypothesis test explain that the t-test value is 4.260, while the t-table value with df 44 is 2.015. The conclusion is that the Problem-Based Learning (PBL) learning model has an effect on improving students'.
