<![CDATA[Young children’s knowledge of dengue prevention remains low due to the limited use of concrete and interactive learning media. This study aims to analyze the effectiveness of behavior board media in enhancing children’s knowledge of dengue prevention in Early Childhood Education. The study employed a Classroom Action Research (CAR) design based on Kurt Lewin’s model, consisting of two cycles, involving 14 children aged 5–6 years in group B at RA Al Munawarah. Data were collected through observation, checklist-based knowledge tests, interviews, and documentation, and analyzed using descriptive quantitative methods based on the percentage of learning achievement. The results showed a significant improvement in children’s knowledge, increasing from 29.04% in the pre-cycle to 62.01% in the first cycle and reaching 86.06% in the second cycle. Improvements were observed in indicators such as recognizing the causes of dengue, understanding preventive measures (3M), maintaining environmental cleanliness, and avoiding mosquito bites. The findings indicate that behavior board media is effective as a visual-interactive stimulus that enhances conceptual understanding and promotes healthy behavior through positive reinforcement and active child engagement. The novelty of this study lies in integrating visual media with a behavioral approach in early childhood health education. Practically, this media can be used as a contextual learning strategy to improve children’s health literacy from an early age.]]>
