Abstract
Critical thinking is a part of higher order thinking ability that require students to develop the process of analyzing or evaluating information on a problem based on logical thinking to determine decissions. But the fact in learning mathemathics, this ability is still not developed well, so that the aplication of problem based learning is expected to be a solution to increase students mathematics critical thinking ability. The purpose of this study is to identity the increasing of students mathematics critical thinking ability as an impact of problem based learning approach. This study was an quasi experimental research. The population of this research is all students in Junior High School of Dwitunggal Tanjung Morawa. The students in VII-1 is choosen as the experimental class and students in VII-2 is choosen as the control class by purposive sampling technique. The data in this study were analyzed using Two Ways ANOVA. The result of this research are the increasing of students mathematics critical thinking ability using problem based learning is higher than regular learning and there is no interaction between mathematics prerequsite ability and learning on students mathematics critical thinking ability.
