This research is motivated by the low learning outcomes in IPAS (Integrated Science and Social Studies) among students. Therefore, this study aims to determine the effect of implementing the Problem-Based Learning (PBL) model with the help of Wordwall media in IPAS learning on the learning outcomes of fifth-grade students. This research uses a quantitative approach with a quasi-experimental type and a one-group pretest-posttest design. The population of this study consists of all fifth-grade students. The sample was taken using a saturated sampling technique. Data collection was carried out using tests with question instruments. After applying the Problem-Based Learning (PBL) model, the average pretest score was 56, and the posttest score was 72, indicating a higher posttest score. Based on non-parametric statistical analysis, it was found that the asymptotic significance (2-tailed) value was 0.000, which is smaller than 0.50, thus the hypothesis is accepted. This means there is a difference between the pretest and posttest results. Therefore, it can be concluded that the hypothesis stating the influence of applying the Problem-Based Learning (PBL) model with the help of Wordwall media in IPAS learning on the learning outcomes of fifth-grade students is accepted.
