Abstract

This study was conducted to describe the implementation of the Problem-Based Learning (PBL) model as an effort to improve the understanding of the concept of living things' life cycles among third-grade students at SDN Pabelan 02 during the 2025/2026 academic year. The study employed the Classroom Action Research (CAR) method, based on the Kemmis and McTaggart model, and was carried out over two learning cycles. Thirty-six students served as the research subjects. Data were collected through observation, interviews, testing, and documentation. Data validity was verified using source and technique triangulation. The findings reveal that the implementation of PBL successfully improved students' understanding of the concepts being studied. The average learning outcome score rose from 70.42 at the initial stage to 76.31 in Cycle I, and further increased to 80.49 in Cycle II. The percentage of classical learning mastery also increased from 44.44% to 66.66%, eventually reaching 83.33%. This improvement occurred because students were actively engaged in learning activities involving problem-solving, group discussions, inquiry, and the presentation of their findings. Therefore, the PBL model proved effective in enhancing elementary school students' understanding of the concept of living things' life cycles.
