The Implementation of the Problem-Based Learning (Pbl) Model to Enhance Mathematical Problem-Solving Skills of Grade Viii Students in Junior High School

The improvement of students' mathematical problem-solving skills (KPMM) is a significant aspect of this research, which also aims to enhance the quality of the learning process. This research is a classroom action research conducted in two cycles during the odd semester of the 2023/2024 academic year, with students in class VIII3 as the research subjects. The learning tools developed include a syllabus, lesson plans (RPP), and learner worksheets (LKPD), while data collection instruments were obtained from teacher and student activity sheets and KPMM tests. The results of this study show that the learning process improved after the implementation of the PBL model in each meeting. The KPMM tests conducted showed an increase in each cycle after the implementation of the PBL model, with the average KPMM test scores in cycle I being 59.8 and in cycle II being 81, higher than the initial test score of 40.6. Based on the results presented, the implementation of the PBL model can enhance the learning process towards a more effective direction and improve the KPMM of students in class VIII3 at SMP Negeri 20 Pekanbaru.
