<![CDATA[This study aims to determine the effect of the use of PhET (Physics Education Technology) media on the ability to understand fraction material in grade VI students with mild intellectual disabilities at SLB Negeri 1 Central Lombok. This study uses a quantitative approach with a one-group pretest-posttest design, with five students with mild intellectual disabilities as research subjects. The data collection technique uses a fraction material comprehension ability test, while data analysis is carried out using the nonparametric Wilcoxon Signed Rank Test. The results of the study show an increase in the ability to understand fraction material after being given treatment using PhET media, which is indicated by an average pretest value of 32.00 and an increase to 88.80 in the posttest. The results of the Wilcoxon test show an Asymp. signed value. (2-tailed) of 0.041, which is smaller than the significance level of 0.05, so that H₀ is rejected and Hₐ is accepted. Thus, it can be concluded that the use of PhET media has a significant effect on the ability to understand fraction material in students with mild mental retardation, because PhET media is able to present abstract fraction concepts in a more concrete, visual, and easy to understand way.]]>
