This study was motivated by the low critical thinking skills of fifth-grade students of SD Negeri 2 Banjarsari Wetan. The problem that occurs is that when the teacher makes questions with the type of questions to measure critical thinking skills, students still do not understand what to do and many students complain when working on these questions because they are considered difficult. The results of some daily tests are still below the Minimum Completeness Criteria (KKM) which has been set at 70. Of the 19 students, only 31.5% (6 students) have met the KKM, while 68.5% (13 students) have not met the KKM. It was found that there are several questions that contain critical thinking indicators such as making conclusions and formulating problems, but students have not been able to digest questions with these types. The purpose of this study was to determine the improvement of students' critical thinking skills by using the Problem Based Learning model. This study used a class action research method. The subjects of this study were fifth grade students of SD Negeri 2 Banjarsari Wetan, Sumbang District, Banyumas Regency, totaling 19 students. The instruments used were critical thinking skills test sheets and learning observation sheets using the Problem Based Learning model. The results of this study showed an increase in students' critical thinking skills in each learning stage carried out using the Problem Based Learning model. In cycle I, the classical completeness was 62.3% with 12 students who were complete. Then in cycle II the completeness increased to 84.2% with 16 students who were complete, and there were only 3 students who were not complete
