Improving the Students’ Mathematics Learning Outcomes of SMPN 23 Pekanbaru by Implementing a Problem-Based Learning Model

This study aims to determine the results of learning mathematics for class VIII students of SMP Negeri 23 Pekanbaru in the odd semester of 2022/2023 by applying a problem-based learning paradigm. This particular study is a classroom action study (CAR) focusing on Kemmis and McTaggart's design. The subject of this study was a group of 36 grade VIII students. This research was conducted in two cycles, and each was carried out in 4 meetings. The results of the study show that the development of a problem-based learning model can improve student learning outcomes by doing the following: 1) student organization on problems, namely the teacher will provide the necessary material; 2) guide students to learn, namely the teacher presents math problems; 3) investigate independent, or group investigations, namely students independently or in groups looking for solutions to the questions asked; 4) presentation or presentation of the results obtained; 5) Evaluation requires teachers and students to assess the results of group discussions.
