<![CDATA[The low learning outcomes in IPAS at the elementary school level indicate the need for learning media capable of increasing student engagement in the learning process. Although various game-based media have been widely developed, media that integrate the Monopoly game with pop-up visualizations for IPAS learning are still rarely used. This study aims to determine the effect of the Monopop (Monopoly Pop-Up) media on the IPAS learning outcomes of fifth-grade students at SD Negeri 1 Kasugengan Kidul. The study employed a quantitative approach using a pre-experimental one-group pretest-posttest design involving 29 students. Data were collected using multiple-choice tests that met validity and reliability criteria and were then analyzed using the Shapiro-Wilk test, the paired-sample t-test, and the N-Gain measure. The results showed a significant difference between learning outcomes before and after the use of the Monopop medium (Sig. = 0.000 < 0.05), with an average N-Gain of 0.6356, which falls into the moderate category. These findings indicate that the Monopop (Monopoly Pop-Up) medium is effective in improving IPAS learning outcomes through more active, interactive, and collaborative learning. The contribution of this study lies in the development of a Game-Based Learning medium that integrates elements of the Monopoly game and pop-up visualizations into a single learning medium. In practice, the Monopop (Monopoly Pop-Up) medium can serve as an alternative for elementary school teachers to support student-centered IPAS learning and create more meaningful learning experiences.]]>
