<![CDATA[This study aimed to determine the effect of the Problem-Based Learning (PBL) model based on a deep learning approach on the IPAS learning outcomes of fifth-grade elementary school students, particularly on the "Bumi Berubah" topic. The research method used was quantitative with a Pre-Experimental Design approach in the form of a One Group Pretest-Posttest Design. The research population included all fifth-grade students totaling 26 learners, with the sampling technique using saturated sampling. The data collection instrument was a multiple-choice learning outcome test consisting of 20 valid and reliable items. Quantitative data analysis was performed using the Paired Sample t-test parametric statistical test assisted by IBM SPSS Statistics version 25. The results showed a significant increase in the mean score of students' learning outcomes, from 62.69 in the pretest to 80.77 in the posttest. Based on the hypothesis testing, the significance value (Sig. 2-tailed) obtained was 0.000, which is smaller than the significance level of 0.05 (0.000 < 0.05), meaning H0 was rejected and Ha was accepted. Therefore, it can be concluded that the implementation of the Problem-Based Learning model based on a deep learning approach has a significant effect on improving the IPAS learning outcomes of fifth-grade elementary school students. This integration model is recommended as an effective alternative learning model for teachers to create an active, meaningful, and enjoyable learning process.]]>
