<![CDATA[The low IPAS learning outcomes are caused by the limited use of learning models and interactive media in the learning process. This study aimed to analyze the effect of implementing the Problem Based Learning (PBL) model assisted by interactive PowerPoint media on the IPAS learning outcomes of third-grade students at SD Negeri Krandon Lor 01. This research employed a quantitative approach using a Pre-Experimental Design with a One-Group Pretest–Posttest Design. The research subjects consisted of 12 students selected using a saturated sampling technique. Data collection techniques included interviews, documentation, and learning outcome tests. Data analysis was conducted using the Shapiro–Wilk normality test, paired sample t-test, and descriptive analysis. The results showed that the pretest and posttest data were normally distributed, and the paired sample t-test obtained a significance value of 0.001 < 0.05, indicating a significant difference in learning outcomes before and after the treatment. Therefore, the implementation of the Problem Based Learning model assisted by interactive PowerPoint media has a significant effect on improving IPAS learning outcomes of third-grade elementary school students.]]>
