<![CDATA[Fractions are one of the mathematics topics that are still difficult for junior high school students to understand, especially in mixed fraction addition operations. These difficulties affect students’ learning outcomes. This study aimed to determine the effect of interactive learning media based on KineMaster on the learning outcomes of seventh-grade students at SMP PGRI Pagaralam. The research method used was an experimental method with a Pretest-Posttest Control Group Design. The population consisted of all seventh-grade students of SMP PGRI Pagaralam in the 2025/2026 academic year. The sample consisted of class VII.4 as the experimental class and class VII.3 as the control class. Data collection techniques used essay tests on mixed fraction addition material. The data analysis techniques employed include a normality test, a homogeneity test, and hypothesis testing using an independent sample t-test. The research results indicate that the post-test data for both the experimental and control groups are normally distributed and homogeneous. Based on the hypothesis test, the significance value is less than 0.05; therefore, the null hypothesis H0 is rejected, and H1 is accepted. The mean post-test score for students in the experimental group is higher than that of the control group 81.15 for the experimental group compared to 66.08 for the control group. Interactive learning media based on KineMaster provided videos, animations, audio, and contextual examples that helped students understand fraction concepts in a more interesting and meaningful way. Therefore, KineMaster-based interactive learning media had an effect on students’ learning outcomes in fraction material.]]>
