This research aims to determine the effect of the Problem Based Learning (PBL) model assisted by Wordwall interactive media on the science and social studies (IPAS) learning outcomes of fifth-grade students at SD Inpres 3/77 Bune. The study addresses the low science literacy and suboptimal learning processes observed at the school. This quantitative research used a pre-experimental method with a one-group pretest-posttest design. The sample consisted of 17 students selected through total sampling. Data collection techniques included multiple-choice tests and observation sheets. Data were analyzed using descriptive and inferential statistics, specifically the Paired Sample T-Test. The results showed that the average pretest score of 68.24 increased to 87.06 in the posttest, indicating an increase of 18.82 points. Hypothesis testing obtained a significance value (Sig. 2-tailed) of <0.001, which is smaller than 0.05. It can be concluded that the application of the PBL model assisted by Wordwall interactive media has a significant positive influence on the IPAS learning outcomes of fifth-grade students at SD Inpres 3/77 Bune.
