Efforts to Build Students' Mathematical Problem-solving Ability Through Problem-based Learning Models on Number Operation Materials in Class VII SMPN 25 Malang

Abstract

The background of this research is students’ low mathematical problem-solving ability. The purpose of this study was to determine the efforts to build mathematical problem-solving abilities of junior high school students, especially in the number operations material caused by the lack of attention and involvement of students in the learning process, students’ difficulties in understanding story problems related to contextual problems, and students who were less active and creative. in constructing problem-solving ideas. Therefore, we need a learning model that can build students’ mathematical problem-solving skills, namely the problem-based learning model. This research was conducted at SMPN 25 Malang as classroom action research (CAR) which refers to the MC Taggart learning model which was carried out for two cycles. The study was carried out on 31 students of class VII.C. The results of this study indicate that the test results of students’ mathematical problem-solving abilities have changed for the better from cycle I to cycle II, where in cycle II the average score has reached 76 and the criteria for completeness have exceeded the mastery limit, which is 87.10%. In this case, it can be concluded that the application of the problem-based learning model can build the mathematical solving abilities of students in class VII-C of SMPN 25 Malang.
