Peningkatan Hasil Belajar IPAS pada Siswa Kelas IV melalui Pembelajaran Berbasis Masalah di SD Negeri Perintis B

This study aims to improve the learning outcomes of fourth grade students in the subject of Natural and Social Sciences (IPAS) through the application of problem-based learning (PBL) models at SD Perintis B. The method used is classroom action research (PTK) which is carried out in two cycles. Data were collected through pre-test, post-test, observation of student activities, and motivation questionnaires. The results of the study showed that the application of PBL can improve student learning outcomes, with the average post-test score increasing significantly compared to the pre-test. In addition, student involvement in the learning process also increased, with 80% of students actively participating in group discussions. This study provides empirical evidence that the problem-based learning model is effective in improving students' understanding of the IPAS material and can be used as an alternative to a more interactive teaching method. These findings are expected to provide a positive contribution to the development of learning methods in elementary schools.
