<![CDATA[This research is motivated by the low mathematics learning outcomes of grade IV A students on the topic of fractions at SD Negeri 2 Penedagandor, as well as the insufficient use of learning media in the teaching process. This study aims to determine the effect of the deep learning approach through PhET simulation media on the mathematics learning outcomes of fourth-grade students on the topic of fractions at SD Negeri 2 Penedagandor for the 2026 academic year. The type of research used is a pre-experimental type with a one-group pretest-posttest design. The population in this study was all students in class IV A at SD Negeri 2 Penedagandor, totaling 21 students, with a sample of 21 students from class IV A. The instrument used is a mathematics learning achievement test on the topic of fractions, which includes the introduction of fractions, comparing and ordering fractions, and connecting fractions with decimal and percentage forms, in the form of essay questions. The research results showed a significance value of 0.000 < 0.05, thus Hâ‚€ was rejected, meaning there is a significant effect of applying the deep learning approach through PhET simulation media on the mathematics learning outcomes of fraction material for fourth-grade students at SD Negeri 2 Penedagandor. The results of the Normalized Gain (N-Gain) analysis showed an average value of 0.2849, which falls into the low category. Thus, the deep learning approach through PhET simulation media has a significant impact on students' learning outcomes, although the improvement in learning outcomes is in the low category.]]>
