Application of the Problem Based Learning (PBL) Learning Model to Improve Mathematics Learning Outcomes in Rational Numbers

Abstract

This study aims to improve mathematics learning outcomes on rational number material for students in class VII-B of Tri Sakti 1 Catholic Middle School Medan by implementing the Problem Based Learning (PBL) learning model. This research is a collaborative classroom action research carried out in 2 cycles. The subjects of this study were students of class VII-B of Tri Sakti 1 Catholic Middle School Medan in the 2023/2024 academic year. The data collection technique used was the test technique. The results of the study showed that the percentage of student learning completion increased from cycle 1 to cycle 2. In cycle 1, the percentage of learning completion was 41% with an average score of 63.5, while in cycle 2, the percentage increased to 75% with an average score of 80.2. Thus, it can be concluded that the Problem Based Learning (PBL) learning model is effective in improving student learning outcomes in mathematics learning on rational number material. For further research, it can be considered to conduct a more in-depth analysis of the factors that influence the improvement of learning outcomes, such as interaction between teachers and students, and the influence of the learning environment.
