<![CDATA[The purpose of this study is to ascertain how the use of visual aids, such as refusi boards, affects the learning outcomes of mathematics students at Al-Munir Islamic Junior High School when studying Relations and Functions. The study employed a posttest-only control group design and a quasi-experimental research methodology. Two classes made up the research sample: the experimental class, which learned using a refusi board as a visual aid, and the control group, which learned using traditional techniques devoid of visual aids. A post-treatment mathematics learning outcome test was used to collect data. The two groups' learning outcomes differed significantly, as indicated by the Asymp. signature value (2-tailed) of 0.033 (<0.05), which was obtained from data analysis using the Mann-Whitney U test. In comparison to the control class, which had an average rank of 21.14 for student learning outcomes, the experimental class had an average rank of 29.86. These findings suggest that using a refusion board as a visual aid improves students' learning outcomes in mathematics when it comes to Relations and Functions. As a result, this media is suggested as a different but equally effective learning method for enhancing comprehension of mathematical ideas.]]>
