<![CDATA[This study aims to determine the significant effect of the Discourse Multi Representation (DMR) learning model on the problem-solving abilities of eighth-grade students at the Yayasan Perguruan Gajah Mada Medan Timur. The sample of this study was 32 eighth-grade students at the Yayasan Perguruan Gajah Mada Medan Timur, in the 2024/2025 academic year. This type of research is Pre-Experimental Research with a One Group Pretest-Posttest design. Quantitative research using one sample group, where measurements are carried out twice: before (pre-test) and after (post-test) treatment is given. The results showed that the average pre-test score was 59.53 and the post-test was 83.36. This indicates that the application of the Discourse Multi Representation (DMR) learning model has a good impact on improving students' abilities in solving mathematical problems. Furthermore, with a hypothesis test of a significance level of 0.001 <0.05, H0 is rejected and Ha is accepted. This means that the Discourse Multi-Representation (DMR) learning model has an effect on the mathematical problem-solving abilities of eighth-grade students at the Yayasan Perguruan Gajah Mada Medan Timur. Based on these results, it can be concluded that the DMR learning model is effective in improving students' mathematical problem-solving abilities.]]>
