This study aims to analyze the effectiveness of the Project Based Learning (PjBL) model on student learning outcomes and skills at the elementary school level. The method used is a Systematic Literature Review (SLR) by reviewing and synthesizing 10 reputable journal articles published in the last three years from 2024-2025. The results of the study indicate that the implementation of PjBL can significantly improve students' conceptual understanding, independence, and problem-solving skills due to its relevance to real-life everyday experiences. Although proven effective, the success of this model is highly dependent on the role of the teacher as a facilitator and the readiness of supporting devices. Thus, PjBL is a very potential alternative learning strategy in elementary schools, as long as it is carefully planned according to the stage of students' cognitive development.
