<![CDATA[The objectives of mathematics learning have not been achieved by students, the cause of the low ability to solve mathematical problems is that they are not used to answering non-routine questions. The target of the study was to see whether the ability to solve mathematical problems of class VIII students of SMPN 2 Kamang Magek using the PBL model could be improved. The research was in the form of an experiment, namely a quasi-experiment, in the form of Nonequivalent Posttest Only Control Group. The population was all class VIII students of SMPN 2 Kamang Magek in the academic year 2024/2025. The sample was taken using the total sampling technique. The samples taken were the entire population, namely classes VIII.1, and VIII.2. Theiresearchiinstrument was in the form of a final test of mathematical problem-solving ability in the form of a description. The dataiobtained were tested using normality tests, homogeneity of variance, and hypotheses. The results of the mathematical problem-solving ability test using the t-test method obtained P-Value = 0.04 which is smaller than α = 0.05 which means rejecting H0. It was concluded that students who took part in learning using PBL had the best mathematical problem-solving ability of those who took part in learning with the Direct Learning model.Keywords– mathematical problem solving ability, PBL model, direct learning model]]>
