This study aims to determine the effect of the PADI (Diagram Board) learning media on the mathematics learning outcomes of Grade III students at SD Cinta Kasih, Sorong City, particularly on fraction material. A pre-experimental research design with a one-group pretest-posttest design was adopted to obtain objective data. The research sample comprised 22 Grade III students selected through total sampling. Data collection was carried out using multiple-choice pretest and posttest instruments. Data analysis included validity testing, reliability testing, normality testing using the Shapiro-Wilk test (SPSS version 27), and hypothesis testing through the paired sample t-test. Reliability analysis yielded a Cronbach's alpha of 0.679 for the pretest and 0.70 for the posttest, both exceeding the minimum threshold of 0.6. Normality test results showed Shapiro-Wilk significance values of 0.549 and 0.664 for the pretest and posttest, respectively, both greater than 0.05, indicating normal data distribution. Hypothesis testing produced a t-count of 9.988 with degrees of freedom n-1 (22-1 = 21), yielding a t-table of 1.721. Based on a significance level of 0.05 (Sig. = .000 < 0.05), H₂ is accepted and H₁ is rejected, confirming that the PADI (Diagram Board) learning media has a significant positive effect on the mathematics learning outcomes of Grade III students at SD Cinta Kasih, Sorong City.
