This research aims to know the effect of problem based learning on mathematical critical thinking skills of junior high school students. This research is a quasi-experimental study with a non-equivalent control group design. This research was carried out in class VIII in one of the junior high school in Bandung, West Java Province, academic year 2014/2015 on relations and functions. Determination of the sample was conducted with purposive sampling and two classes were selected as the research sample, namely class VIII.C as the experimental class that received problem based learning and class VIII.F as the control class that received learning with the scientific approach. The results showed that the average post-test for problem based learning was 42.16 and the average posttest of the learning class with a scientific approach was 35.27. Then after being analyzed using the t-test obtained a significance value of 0.024 < 0.05. It can be concluded that there is an effect of problem based learning on mathematical critical thinking skills of junior high school students.
