<![CDATA[This study aimed to determine the effect of the Problem-Based Learning (PBL) model assisted by Wordwall media on the Science and Social Studies (IPAS) learning outcomes of fourth-grade students at SD Negeri 065011 Medan Selayang in the 2025/2026 academic year. The study employed a quantitative approach using an experimental method with a pre-experimental One-Group Pretest-Posttest Design. The subjects consisted of 25 fourth-grade students. Data were collected through a learning outcomes test consisting of multiple-choice questions administered before (pretest) and after (posttest) the implementation of the learning model. Prior to use, the research instrument was tested for validity, reliability, item difficulty, and discrimination power. Data analysis involved a normality test and hypothesis testing using a paired-samples t-test. The results showed that the mean pretest score of 60.8 increased to 81.68 on the posttest. Hypothesis testing yielded a significance value (Sig. 2-tailed) of 0.000 < 0.05, with a calculated t-value of 10.921, greater than the critical t-value of 2.069. Therefore, H? was rejected and H? was accepted. Thus, PBL assisted by Wordwall media had a significant effect on the IPAS learning outcomes of fourth-grade students.]]>
