<![CDATA[This study aims to determine the influence of using the Problem-Based Learning (PBL) model assisted by Wordwall media on the improvement of IPAS (Science and Social Studies) learning outcomes of fourth-grade students at SD Negeri 50 Kota Bengkulu. The research used a quantitative approach with a quasi-experimental design. The sampling technique applied was saturated sampling, involving class IV A as the experimental group with 20 students and class IV B as the control group, also with 20 students. Data were collected through observation, interviews, documentation, and tests consisting of 10 multiple-choice questions. The test results were analyzed using the Independent Samples T-Test with the aid of SPSS version 25. Based on the findings, it can be concluded that the Problem-Based Learning model assisted by Wordwall media is effective in improving IPAS learning outcomes. This is evidenced by the statistical test results showing a significance value (Sig. 2-tailed) < 0.05, with a pre-test significance value of 0.040 and a mean difference of 7.500, as well as a post-test significance value of 0.000 and a mean difference of 42.000. Since these significance values are smaller than α = 0.05, the null hypothesis (H₀) is rejected and the alternative hypothesis (H₁) is accepted, indicating a significant difference in learning outcomes between the experimental and control classes. Therefore, it can be concluded that the use of the Problem-Based Learning model assisted by Wordwall media is effective in improving the IPAS learning outcomes of fourth-grade students at SD Negeri 50 Kota Bengkulu.]]>
