This study aimed to determine the effectiveness of the problem based learning model on the problem solving ability of high school students. This research is a quasy experimental research with the matching only pretest-posttest control group design. The subjects in this study were students of class XI IPA SMA Negeri 1 Ulubelu. The effect size hypothesis test is used to obtain the results of the effectiveness of the PBL model on students’ problem solving abilities.
