The Effect of the Problem-Based Learning Model on Students’ Problem-Solving Skills in the Topic of Prims in Eight Grade Junior High School

One of the objectives of mathematics learning in merdeka curriculum that is currently implemented is problem solving ability. Problem solving ability is an important ability and must be possessed by students, especially in learning mathematics. The learning process at school can be carried out using a learning model. One of the learning models that can be applied is the Problem Based Learning (PBL) learning model. This study aims to analyze the effect of using the Problem Based Learning (PBL) learning model in prism falt-sided space building material on the mathematical problem solving skills of 8th grade student. The research method used is an experiment with a one-group pretest-posttest design. The research subjects were students of class VIII A SMP Muhammadiyah 3 Yogyakarta. Data were obtained through problem solving ability tests before and after using the Problem Based Learning (PBL) learning model. The results showed that the n-gain core was in the high category of 0,83, while the results of hypothesis testing obtained tcalculated = 40,396 more than ttable = 2,086 which means is rejected and is accepted. So it can be concluded that there is an effect of problem-based learning (PBL) learning model on the mathematical problem solving ability of 8th grade students of SMP Muhammadiyah 3 Yogyakarta.One of the objectives of mathematics learning in merdeka curriculum that is currently implemented is problem solving ability.
