ABSTRACT
Based on a preliminary study at SDN Karangsono 1 that students had difficulty to solve problem-solving questions or questions presented in the form of stories, especially geometric material. The purpose of this study was to determine the ability to solve mathematical problems with the PBL model with the RME approach better than the PBL learning model. This study used a quantitative design with an experimental class and a control class. Data collection techniques used are tests and non-tes. The data analysis technique in this research is prerequisite test and hypothesis test. The results of this study were that the average mathematical solving ability of students using the PBL model with the RME approach is better than using the PBL model alone. This can be proved from the experimental class, the average indicator 1 during the pretest is 70 and when the posttest becomes 77, in indicator 2 during the pretest the average is 60 and becomes 73 during the posttest, in indicator 3 during the pretest the average is 50 and becomes 80 during the posttest, on the other hand in indicator 4 during the pretest the average is 53 and becomes 73 during the posttest. Meanwhile, in the control class in indicator 1 the average pretest was 50 and it became 65 during the posttest, in indicator 2 the average during the pretest was 60 and it became 70 during the posttest, in indicator 3 the average was 50 and it became 60 when posttest, and on indicator 4 the average is 55 to 60 during the posttest. This shows that students' mathematical problem-solving skills in the experimental class are better than those in the control class.
