Application of the Problem Based Learning Model in Mathematics Learning to Improve Critical Thinking Skills for Class III Students of SD Tamansiswa Jetis

Abstract

Mathematics is a field of science that has abstract objects and can improve thinking skills and provide assistance in solving everyday problems. The Problem Based Learning model is a learning model that presents problems for students to solve both individually and in groups by understanding the concepts of existing problems in order to stimulate students' critical thinking to solve problems in a way that they understand. This study aims to improve students' critical thinking skills through the application of the Problem Based Learning model at Tamansiswa Jetis Elementary School. This type of research is collaborative classroom action research which consists of two cycles. The participants in this study were grade III SD Tamansiswa Jetis semester 2 of the 2022/2023 academic year, with a total of 16 students. The data collection technique used consists of test and non-test techniques which involve observation and documentation. The results of this study indicate that the application of learning models can improve students' critical thinking skills in learning mathematics. The average students' ability to think critically increased from pre-cycle by 53.4%, cycle I by 63%, and cycle II by 79.7%. This shows that students' critical thinking skills increased from cycle I to cycle II by 16.7%. So it can be concluded that the problem-based learning model can improve critical thinking skills in learning mathematics for third grade students at Tamansiswa Jetis Elementary School.
