Abstract
This study was motivated by the low learning outcomes of third-grade students at SDN Klegen 02 regarding the topic of diverse landforms and the associated professions of the local community. The study aimed to improve student learning outcomes through the implementation of the Problem-Based Learning (PBL) model supported by Educaplay media. This research was conducted as Classroom Action Research (CAR) spanning two cycles, with each cycle comprising the stages of planning, implementation, observation, and reflection. The subjects were 18 third-grade students at SDN Klegen 02. Data collection utilized a 20-item multiple-choice test, with a Minimum Mastery Criterion (KKM) set at 75. The results demonstrated a significant improvement: the average score in the pre-test was 54.4, with a classical mastery rate of 11.1%. Following instruction in Cycle I, the average score rose to 70.0, with a classical mastery rate of 55.6%. In Cycle II, the average score further increased to 85.8, achieving a classical mastery rate of 94.4%. Thus, the PBL model supported by Educaplay media proved effective in enhancing the learning outcomes of third-grade students at SDN Klegen 02.
