Application of the Problem-Based Learning (PBL) Model to Enhance Students' Mathematics Learning Outcomes

Abstract

This research started with the problem of low Mathematics learning outcomes for first graders of SDN in Yogyakar under the Minimum Completeness Criteria (KKM), namely 65. Out of 28 students only 25 students who achieve KKM is about 50%. The aim of the research is to improve the results learning Mathematics first grade students of SDN in Yogyakarta. This research is an action research class (CAR) which was carried out in 5 cycles. This research was carried out in class 1 at a public elementary school in Yogyakarta for the 2022/2023 academic year with a total of 28 students. Based on the results of the discussion and the analysis concluded through the application of problem based learning (PBL) learning models can improve students' Mathematics learning outcomes in the materials of Spatial and Flat Shapes. The increase in teacher activity in the learning process is due to the fact that the teacher is used to it using the problem based learning (PBL) learning model. Student learning outcomes experience improvement from cycle II to cycle V. Student learning outcomes before the action reached KKM only 25 students with a classical average of 50%. Then in cycle II students who achieve KKM is only 26 students with a classical average of 70%. Cycle III-V students who achieve KKM 27 students with a classical average of 98%.
