This study explores the potential of Problem-Based Learning (PBL) in primary school education and investigates its impact on geography skills, learning achievement, and satisfaction. The purpose of the study is to assess the effectiveness of PBL as a student-centered approach in enhancing learning outcomes. The participants consisted of 43 grade 5 students from schools in Thailand, selected through cluster random sampling. The study employed geography skill and learning achievement assessments, along with satisfaction surveys, as research instruments. The results revealed significant improvements in participants' geography skills and learning achievement, with high levels of satisfaction reported. These findings highlight the effectiveness of PBL in primary school education and underscore the importance of implementing student-centered approaches. Further research is recommended to examine the long-term effects and sustainability of PBL implementation in primary school settings, promoting ongoing advancements in educational practices.
