The low critical thinking ability of students is caused by the lack of students getting a problem that can sharpen their thinking patterns critically through learning models. One learning model that can improve students' critical thinking skills is problem based learning. The problem based learning model is a learning model that uses authentic/real problems to gain knowledge and make decisions by solving problems and requires the ability to think critically. The aim of this research is to determine the effect of the based learning model on students' critical thinking abilities. The method used in this research is experimental.
