<![CDATA[This research was motivated by the low learning outcomes in Natural and Social Sciences (IPAS) among elementary school students, resulting from instruction that was still dominated by the lecture method and a lack of engaging learning media. This condition caused students to be less actively involved and to have limited understanding of the material being taught. This study aimed to determine the effect of the Read Answer Discuss Explain Create (RADEC) learning model assisted by diorama media on elementary school students' IPAS learning outcomes. This research employed a quantitative approach with a quasi-experimental method, using a pretest-posttest control group design. The population consisted of all third-grade students of SDN Jiwan 01, Madiun Regency, in the 2025/2026 academic year. The research sample comprised 42 students, divided into an experimental class and a control class. Data were collected through pretest and posttest. The research instrument consisted of multiple-choice questions that had been tested for validity and reliability. Data analysis techniques included normality tests, homogeneity tests, and hypothesis testing using IBM SPSS version 25. The results showed that the average posttest score of the experimental class was 88.86, higher than that of the control class at 68.67. The hypothesis test results obtained a significance value of 0.000 < 0.05, leading to the rejection of H0 and the acceptance of H1. Thus, it can be concluded that the RADEC learning model assisted by diorama media has a significant effect on elementary school students' IPAS learning outcomes.]]>
