Penggunaan Model Problem Based Learning Untuk Meningkatkan Proses Dan Hasil Belajar IPAS

Abstract

This study was motivated by the low level of student engagement in the learning process and the learning outcomes of Natural and Social Sciences (IPAS) that have not yet reached the Minimum Completion Criteria (KKM). The purpose of this study was to improve the IPAS learning process and outcomes through the application of the Problem-Based Learning (PBL) model. This study was a Classroom Action Research (CAR) conducted in two cycles. The research subjects were 17 fourth-grade students at SDN 71/II Sungai Gambir in the second semester of the 2024/2025 academic year, consisting of 8 male students and 9 female students. Each cycle consisted of the planning, implementation, observation, and reflection stages. Data was collected through observations of teacher and student activities, as well as learning outcome tests. The research results indicate that the implementation of PBL effectively improved the quality of the learning process and student learning outcomes. Teacher activities improved from the “good” category in Cycle I to “very good” in Cycle II. Student activities also showed improvement, shifting from passive in Cycle I to more active, creative, and collaborative in Cycle II. In addition, the percentage of student learning achievement increased significantly from 64.7% in cycle I to 88.2% in cycle II. Thus, it can be concluded that the use of the Problem Based Learning model is effective in improving the IPAS learning process and outcomes for fourth-grade students at SDN 71/II Sungai Gambir. PBL can be used as an alternative student-centered learning strategy, encouraging critical thinking skills and creating more meaningful learning.
